General
Description
Altera FLEX 10 KE devices are enhanced versions of FLEX 10K devices.
Based on reconfigurable CMOS SRAM elements, the FLEX architectur e
incorporates all features necessary to implement common gate array
megafunctions. With up to 200,000 typical gates, FLEX 10KE devices
provide the density, speed, and features to integrate entire systems,
including multiple 32-bit buses, into a single device.
The ability to reconfigure FLEX 10KE devices enables 100% testing prior
to shipment and allows the designer to focus on simulation and design
verification. FLEX 10KE reconfigurability eliminates inventory
manag ement for gate arr ay designs a nd gener ation of te st vector s for fault
coverage.
Table 5 shows FLEX 10KE performance for some common designs. All
performance values were obtained with Synopsys DesignWare or LPM
functions. Special design techniques are not requir ed to implement the
applications; the designer simply infers or instantiates a function in a
Verilog HDL, VHDL, Altera Hardware Description Language (AHDL), or
schematic design file.

Similar to the FLEX 10KE architecture, embedded gate arrays are the
fastest- g row ing segment of th e g ate array mar k et . As with stand ard gat e
arrays, embedded gate arrays implement general logic in a conventional
“sea-of-gates” architecture. Additionally, embedded gate arrays have
dedicated die areas for implementing large, specialized functions. By
embedding functions in silicon, embedded gate arrays reduce die area
and increase speed when compare d to standard gate arrays. While
embedded megafunctions typically cannot be customized, FLEX 10KE
devices are programmable, providing the designer with full control over
embedded megafunctions a nd general logic, while facilitating iterative
desig n c hanges during debuggi ng.
Each FLEX 10KE device contains an embedded array and a logi c ar ray.
The em be dded array i s used to impl ement a var iety of memor y fu nctio ns
or complex logic functions, such as digital signal processing (DSP), wide
data-path manipulation, microcontroller applications, and data-
transformation functions. The logic array performs the same function as
the sea-of-gates in the gate array and is us ed to implemen t general logi c
such as counters, adders, state machine s, and multiplexers. The
combination of embedded and logic arrays provides the high
performan ce and hi gh densit y of emb edded gate arrays, enablin g
desi gn ers to implem e nt an ent i re sys te m on a single devic e.
FLEX 10KE devices are configured at system power-up with data stored
in an Altera serial configuration device or provided by a system
controller. Altera offers the EPC1, EPC2, and EPC16 configuration
devi ce s, whi ch configur e FLEX 10KE devices via a serial data stream.
Configurat ion d ata ca n a lso b e dow nloa ded fr om syste m RAM or via th e
Altera B it Bla st er TM, ByteB lasterMVTM, or MasterBlas te r dow nloa d cabl e s.
After a FLEX 10KE device has been configured, it can be reconfigured
in-circuit by resetting the device and loading new data. Because
reconfiguration requires less than 85 ms, real-time changes can be made
during system operation.
FLEX 10KE devices contain an interface that permits microprocessors to
configure FLEX 10KE d evices se ri ally or in-parallel, a nd synchrono usly or
asynchronously. The interface also enables microprocessors to treat a
FLEX 10KE device as memory and configure it by writing to a virtual
memory location, making it easy to reconfigure the device.

FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces D ata Sheet
Functional
Description
Each FLEX 10KE device contains an enhanced embedded array to
implement memory and specialized logic functions, and a logic array to
implement general logic.
The embedded array consists of a series of EABs. When implementing
memory functions, each EAB provides 4,096 bits, which can be used to
create RAM, ROM, dual-port RAM, or first-in first-out (FIFO) functions.
When implementing logic, each EAB can contribute 100 to 600 gates
towards complex logic functions, such as mult ipliers, microcontrollers,
state machines, and DSP functions. EABs can be used independently, or
multiple EABs can be combined to implement larger functions.
The logic array consists of logic array blocks (LABs). Each LAB contains
eight LEs and a local int erconnec t. An LE consists of a four-input look-up
table (LUT), a programmable flipflop, and dedicated signal paths for carry
and cascade functions. The eight LEs can be used to create medium-sized
blocks of logic—such as 8-bit counters, address decoders, or state
machines—or combined across LABs to create larger logic blocks. Each
LAB represents about 96 usable gates of logic.
Signal inte rconnect ions within FLEX 10KE devices (as well as to and from
device pin s) ar e provided by the Fas tT rac k Intercon nect routin g structur e,
which is a serie s of fast, continuous r ow and column ch annels that run th e
entire length and width of the dev ice.
Each I/O pin is fed by an I/O element (IOE) located at the end of each row
and column of the FastTrack Interconnect routing structure. Each IOE
contains a bidirectional I/O buffer and a flipflop that can be used as either
an output or input register to feed input, output, or bidirectional signals.
When used with a dedicated clock pin, these registers provide exceptional
performance. As inputs, they provide setup times as low as 0.9 ns and
hold times of 0 ns. As outputs, these registers provide clock-to-output
times as low as 3.0 ns. IOEs provide a variety of features, such as JTAG
BST support, sle w-rat e cont ro l, tri-s tate buf fers, and open-drain outp uts .

device.

Embed ded A rray Bloc k
The EAB is a flexible block of RAM, wit h registers on the inpu t and output
ports, that is used to implement common gate array megafunctions.
Because it is large and flexible, the EAB is suitable for functions such as
multipliers, vector scalars, and error correction circuits. These functions
can be combined in applications such as digital filters and
microcontrollers.
Logic functions are implemented by programming the EAB with a read-
only patte rn during configuration, thereby creating a large LUT. With
LUTs, combinatorial functions are implemented by looking up the results,
rather than by computing them. This implementation of combinatorial
functions can be faster than using algorithms implemented in general
logic, a performan ce advanta ge that is furt her enhanc ed by the fast a ccess
times of EABs. The large capacity of EABs enables designers to implement
complex fun ctions in on e logic leve l without t he routin g delays as sociated
with linked LEs or field-programmable gate array (FPGA) RAM blocks.
For exam ple, a single EA B can imple ment any function with 8 inp uts an d
16 outputs. Parameterized functions such as LPM functions can take
advantage of the EAB automatically.
The FLEX 10KE EAB provides adva ntages over FPGAs, which implement
on-board RAM as arrays of small, distributed RAM blocks. These small
FPGA RAM blocks must be connected together to make RAM blocks of
manageable size. The RA M blocks ar e conne cted together us ing
multiplexers implemented with more logic blocks. These extra
multiple xers cause extra del ay, which slo ws down the RAM block . FPGA
RAM blocks are also prone to routing problems because small blocks of
RAM m ust be connec ted tog ether to m ake larger bl ocks. In co ntrast, E ABs
can be used to implement large, dedicated blocks of RAM that eliminate
th ese timing and routing con cerns.
The FLEX 10KE e nhanced EAB adds dual-p o rt capability to the existing
EAB structure. The dual-port structure is ideal for FIFO buffers with one
or two clocks. The FLEX 10KE EAB can also support up to 16-bit-wide
RAM blocks and is backward-compatible with any design containing
FLEX 10K EABs. The FLEX 10KE EAB can act in dual-port or single-port
mode. When in dual-port mode, separate clocks may be used for EAB read
and write sections, which allows the EAB to be written and read at
differ e nt rate s. It also has sep ar a te sy nch ro nous cloc k ena b le sig nals for
the EAB read and write sections, which allow independent control of
these s ections.
Altera Corporation 11
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces D ata Sheet
The EAB can also be used for bidirectional, dual-port memory
applications where two ports read or write simultaneously. To implement
this type of dual-port memory, two EABs are used to support two
simulta neous r ead or writes.
Alte rnat ivel y, one clock and clock en able ca n b e use d to con tr ol t he inp ut

write enable s ignal. I n contr ast, t he EAB’ s synchron ous RAM g enerates its
own write enable signal and is self-timed with respect to the input or write

EABs provide flexible options for driving and controlling clock signals.
Different clocks an d clock enables can be used for r ead ing and writing to
the EAB. Registers can be independently inserted on the data input, EAB
output, write address, write enable signals, read address, and read enable
sign als. The glo bal signal s and the EAB loc al intercon nect ca n drive write
enable, read enable, and clock enable signals. The global signals,
dedicated clock pins, and EAB local interconnect can drive the EAB clock
signals. Because the LEs driv e t he EAB local interconn ec t, the LEs can
control write enable, read enable, clear, clock, and clock enable signals.
An EAB is fed by a row in terconnect and can drive out to row and colu mn
inte rconnect s. Ea ch EAB ou tput ca n drive u p to two row channe ls and up
to two column channels; the unused row channe l can be driven by other
LEs. This feature increases the routing resources available for EAB
outpu ts (see Figures 2 and 4). T he c olumn int erc onne ct, which is adjac en t
to the EAB, has twice as many channels a s other columns in the device.
Logic Array Bloc k
An LAB consists of eight LEs, their associated ca rry and cascade chains,
LAB contr ol s i gnals, and the LA B l ocal interconnect. The LA B provides
the coarse-grained structure to the FLEX 10KE architecture, facilitating
efficient routing with optimum device utilization and high performance
(see Figure 7).

Each LAB provides four control signals with programmable inversion
that can be used in all eight LEs. Two of these signals can be used as clocks,
the oth er t wo ca n b e use d for c lea r /pre set control. The L AB clocks can b e
driven by the dedicated clock input pins, global signals, I/O signals, or
internal signals via the LAB local interconnect. The LAB preset and clear
control signals can be driven by the global signals, I/O signals, or internal
signals via the LAB local interconnect. The global control signals are
typi ca lly used for global clock, clear , or preset signa ls because they
provide asynchronous control with very low skew across the device. If
logic is require d on a contr ol sig nal, it can b e genera ted in one or more LE
in any LAB and driven into the local inte rconnect of the target LAB. In
addition, the global control signals can be generated from LE outputs.
Logic Element
The LE, the smallest unit of logic in the FLEX 10KE architecture, has a
compact size that provides efficient logic utilization. Each LE contains a
four-input LUT, which is a function generator that can quickly compute
any function of four variables. In addition, each LE contains a
programmable flipflop with a synchronous clock enable, a carry chain,
and a cascade chain . Each LE dr ives b oth th e loc al and the FastTrack
Interconnect routing structure (see Figure 8).

The programmabl e flipflop in the LE can be config ured for D, T, JK, or SR
operation. The clock, clear, and preset control signals on the flipflop can
be driven by global signals, general-purpose I/O pins, or any internal
logic. For combina toria l funct ions, the flipflop is bypa ssed and the output
of the LUT drives the output of the LE.
The LE has two outputs that drive the interconnect: one drives the local
interconnect and the other drives either the row or column FastTrack
Interconnect routing structure. The two outputs can be controlled
independently. For example, the LUT can drive one output while the
regist er driv es th e oth er outp ut. T his fe atu re, ca lled r egister pac ki ng, can
improve LE utilization because the register and the LUT can be used for
unrelated functions.
The FLEX 10KE arc hitecture provides two ty pe s of ded ica te d h igh -spe ed
data paths that connect adjacent LEs without using local interconnect
paths: carry chains and ca scade chains. The carry chain supports
hi gh-speed counters and ad d e rs and the cascade chain implements
wide-inp ut fu nct ions wit h min i mum del ay . Carry and cascade chains
connect all LEs in a LAB as well as all LABs in the same row. Inte nsive use
of carry and cascade chains can reduce routing flexibility. Therefore, the
use of these chains should be limit ed to speed- critica l portion s o f a des ign.
Carry Chain
The carry chain provides a very fast (as low as 0.2 ns) carry-forward
function be tween LEs. The ca rry-i n signal from a lower - or der bit drives
forward into the higher-order bit via the carry chain, and feeds into both
the LUT and the next portion of the carry chain. This fe ature allows the
FLEX 10KE architecture to implement high-speed counters, adders, and
comparators of arbitrary width efficiently. Carry chain logic can be
creat e d aut omatic ally b y th e Altera Compiler d uri ng design processing,
or manually by the designer during design entry. Parameterized functions
such as LPM and Design Ware function s aut omat ica lly take advan ta ge of
carry chains.
Carry chains longer than eight LEs are automatically implemented by
linking LABs together. For enhanced fitting, a long carry chain skips
al ternate LABs in a r ow. A carry chain longer than one LA B skips either
from even-numbered LAB to even-numbered LAB, or from odd-
nu mbered LAB to odd-number ed LAB. For example, the last LE of the
first LAB in a row carries to the first LE of the third LAB in the row. The
carry c hain does no t c ro ss the EAB at the mi dd le of the r ow. For instance,
in the E PF10 K50E de vice, th e car ry chain stop s at the eight eenth LAB and
a new one beg ins at the nin e tee nth LAB.

Figure 9 shows how an n- bit full adde r can be impleme nte d in n+1 LEs
with the car ry chain. One port ion of th e LUT gene rates the sum of t wo bits
using the input signals and the carry-in signal; the sum is routed to the
output of the LE. The register can be bypassed for simple adders or used
for an accumulator function. Another portion of the LUT and th e carry
chain logic generates th e carry-out signal, which is routed directly to the
carry-in signal of the next-higher-order bit. The final carry-out signal is
routed to an LE, where it can be used as a general-purpose signal.

Cascade Chain
With the cascade chain, the FLEX 10KE architecture can implement
functions that have a very wide fan-in. Adjacent LUTs can be used to
compute portions of the function in parallel; the cascade chain serially
connec ts the i ntermediat e value s. The ca scade ch ain can use a logica l AND
or logical OR (via De Morgan’s inversion) to connect the outputs of
adjace nt LEs. An a delay as low as 0.6 ns per LE, each additional LE
provides four more inputs to the effective width of a function. Cascade
chain logic can be created automatically by the Altera Compiler during
design processing, or manually by the designer during design entry.
Cascade chains longer than eight bits are implemented automatically by
linking se veral LABs together. For easier routing, a long cascade chain
skips every other LAB in a row. A cascade chain longer than one LAB
skips ei ther from even-numbere d LAB to even-n umbered LAB, or fro m
odd-numbe red LAB to odd-numbered LA B (e.g., the last LE of the first
LAB in a row cascades to the first LE of the third LAB). The cascade chain
does not cross the center of the row (e.g., in the EPF10K50E device, the
cascade chain stops at the eighteenth LAB and a new one begins at the
ninet eenth LAB). This break is du e to the EAB’s placement in the middl e
of the row.
Figure 10 shows how the cascade function can connect adjacent LEs to
form functions with a wide fan-in. These examples show functions of
4n variables implemented with n LEs. The LE del ay is 0.9 ns ; th e c as cade
chain delay is 0.6 ns. Wi th the cascade chain, 2. 7 ns are needed to dec ode
a 16-bit address.

LE Operat ing M ode s
The FLEX 10KE LE can operate in the follow ing four modes:
■Normal mode
■Arithmet ic mode
■Up/down counter mo de
■Clea r able cou nter mo d e
Each of these modes u ses LE resources differently . In ea ch mode, seven
available inputs to the LE—the four data inputs from the LAB local
interconnect, the feedback from the programmable register, and the
carry-in and casc ade- i n from t he previous LE—are directed to different
destinations to implement the desired logic function. Three inputs to the
LE provide clock, clear, and preset control for the register. The Altera
software, in conjunction with parameterized functions such as LPM and
DesignWare functions, automatically chooses the appropriate mode for
common functions such as counters, adders, and multipliers. If required,
the designer can also create special-purpose functions that use a specific
LE operating mode for optimal performance.
The a rchitect ure provid es a sy nchro nous cloc k enable t o the register in all
four modes. The Altera software can set DATA1 to enable the register
synchronously, providing easy implementation of fully synchronous
designs.

Normal Mode
The normal mode is suitable for general logic applica tions and wide
de cod ing f un ctions that can take adv a nt ag e of a cas ca de chain. In normal
mode, four data inputs from the LAB local interconnect and th e carry-in
are inpu ts to a fou r-input LUT . The A lte ra Com piler aut omati cally select s
the ca rry-in or the DATA3 signal as one of the inputs to the LUT. The LUT
output can be combined with the cascade-in signal to form a cascade chain
thr ough th e casc ade -out sign al. Either the reg ister or th e LUT ca n be used
to drive both the local interconnect and the FastTrack Interconnect routing
str uct ur e at the same time .
The LUT and the regist er in the LE can be used indep endently (regi ster
packin g). To suppor t regi ster pa cking , the LE h as tw o outputs ; one dr ives
the local interconnect, and the other drives the FastTrack Interconnect
routing st ructure. The DATA4 si gnal can drive the reg ister dir ectly,
allowing the LUT to compute a function that is independent of the
regis tered s ignal; a thre e-input function can be compute d in the LUT, and
a fourth independent signal can be registered. Alternatively, a four-input
function can be generated, and one of the in puts to this function can be
used to drive the register. The register in a packed LE can still use the clock
enable, clear, and preset signals in the LE. In a packed LE, the register can
drive the FastTrack Interconnect routing structure while the LUT drives
the local interconnect, or vice versa.
Arithmetic Mode
The arithmetic mode offers 2 three-input L UTs th at are ideal for
implementing adders, accumulators, and comparators. One LUT
computes a three-input function; the other generates a carr y output. As
shown in Figure 11 on page 22, the first LUT uses the car r y-in si gnal and
two data inputs from the LAB local interconnect to generate a
combi nator ial o r regi ste r ed out put. For e xample , in a n a dde r, th is output
is the sum of three signals: a, b, and carry-in. The second LUT uses the
same thr e e signals to ge ne rate a carry-out signal, th er eb y cre ating a carr y
chai n. The ar ithmetic m ode al so support s simultane ous use of the casc ade
chain.
Up/Down Counter Mode
The up/down counter mode offers counter enable, clock enable,
synchronous up/down control, and data loading options. These control
sign als ar e g e ner a te d by the da ta inpu ts f rom th e L AB loca l int er co nne ct,
the carry-in signal, and output feedback from the programmable register.
Use 2 three-input LUTs: one generates the counter data, and the other
generates the fast carry bit. A 2-to-1 multiplexer provides synchronous
loading. Data can also be loaded asynchronously with the clear and preset
regist er co ntrol signals wi thout using t he LU T reso urc e s.
24 Altera Corporation
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces D ata Sheet
Cleara ble Counter Mode
The clearable counter mode is similar to the up/down counter mode, but
supports a synchronous clear instead of the up/down control. The clear
function is substituted for the cascade-in signal in the up/down counter
mode. Use 2 three-input LUTs: one generates the counter data, and the
other generates the fast carry bit. Synchronous loading is provided by a
2-to-1 multiplexer. The output of this multiplexer is AND ed with a
synchronou s clear signal.
Internal Tri-State Emulation
Inter nal tri- st at e emulation provide s intern al tr i-st ate s with out the
limitations of a physical tri-state bus. In a physica l tri-state bus, the
tri-st at e bu f fer s’ output enable (OE) signals se lec t whic h sig nal drive s the
bus. Howeve r, if multiple OE sig nals a re ac tive, c ontendi ng si gnals c an be
driven onto the bus. Conversely, if no OE signals are act i ve , the bus will
float. Int ernal tri-st ate em ulation resolve s conte nding tri-s tate buffe rs to a
low value and floating buses to a high value, thereby eliminating these
problems. The Altera software automatically implements tri-state bus
functionality with a multiplexer.
Clear & Preset Logic Control
Logic for the programmable register’s clear and preset functions is
controlled by the DATA3, LABCTRL1, and LABCTRL2 inputs to the LE. The
clear and pres et control str uc ture of the LE asynch r onous ly loads signals
into a register. Either LABCTRL1 or LABCTRL2 can control the
asynchronous clear. Alternatively, the registe r can be set up so that
LABCTRL1 implements an asynchronous load. The data to be loaded is
driven t o DATA3; w hen LABCTRL1 is asserte d , DATA3 is loaded into the
register.
During compil ati on, the Altera Compile r automat ica lly se lects the best
control s i gnal imple m entat ion. Because the c lea r an d pre set fun cti ons are
active-low, the Compiler automatically assigns a logic high to an unused
clear or preset.
The clear and preset logic is implemented in one of the following six
modes ch osen during design entry:
■Asynchronous clear
■Asynchronous preset
■As ynchronou s clear and p r eset
■Asynchronous load with cle ar
■Asynchronous load with preset
■Asynchronous load without clear or preset
Altera Corporation 25
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces Data Shee t
In ad dition t o the six cle ar an d prese t mode s, FLEX 10KE device s provide
a chip-wide reset pin that can reset all registers in the device. Use of this
feature is set during design entry. In any of the clear and preset modes, the
chip-w ide reset overrides all other si gna ls. R e gisters with asynchronous
presets may be preset when the chip-wide reset is asserted. Inversion can
be used to implement the asynchronous preset. Figure 12 shows examples
of how to setup the p reset and c lear inputs fo r the de sire d func tionality.

Asynchronous Clear
The flipflop can be cleared by either LABCTRL1 or LABCTRL2. In this
mod e, the preset signal is tied to VCC to de activate it.
Async hronous Pres et
An asynchronous preset is implemented as an asynchronous load, or with
an asynchronous clear. If DATA3 is tied to VCC, asserting LABCTRL1
asynchronously loads a one into the register. Alternatively, the Altera
software can provide preset control by using the clear and inverting the
input and output of the register. Inve rsion control is available for the
inputs to both LEs and IOEs. Therefore, if a register is preset by only one
of the two LABCTRL signa ls, the DATA3 input is not needed and can be
used for one of the LE operating modes.
Async hronous Pres et & Clear
When implementing asynchronous clear and preset , LABCTRL1 controls
the pr es et an d LABCTRL2 controls the clear. DATA3 is t ied to VCC, so that
asserting LABCTRL1 asynchronously loads a one into the register,
effectively presetting the register. Asserting LABCTRL2 clear s th e reg iste r.
Async hr onous Load with Clear
When implem enting an async hr onou s loa d in conjunction with t he clea r ,
LABCTRL1 implements the asynchronous load of DATA3 by controlling
th e regi ster pr eset and cl ear. LABCTRL2 imple ments the clear by
controlling the register clear; LABCTRL2 do es not hav e to fe ed the pres et
circuits.
Async hr onous Load with Preset
When implementing an asynchronous load in conjunction with preset, the
Altera software provides preset control by using the clear and inverting
the input and output of the regist er. Asserting LABCTRL2 presets the
register, while assertin g LABCTRL1 loads the register. The Altera software
inverts the signal that drives DATA3 to account for the inversion of the
register’s output.
Async hr onous Load without Pr es et or Clear
When implementing an asynchronous load without preset or clear,
LABCTRL1 implements the asynchronous load of DATA3 by controlling
th e regi ster pr eset and cl ear.

FastTrack Int er co nnec t Rout ing Structure
In the FLEX 10KE architecture, connections between LEs, EABs, and
device I/O pins are provided by the FastTrack Interconnect routing
structure, which is a series of continuous horizontal and vertical routing
chan ne ls t hat trav er se s t he devic e. This global routing st r uctu r e prov id es
pred icta ble perf orm ance, even in complex designs. In contrast, the
segmented routing in FPGAs requires switch matrices to connect a
variable number of routing paths, increasing the delays between logic
resour c es and re ducing perfor ma nce .
The F ast Tra ck I nte rconn ec t r outing structure cons ist s of ro w an d colum n
interconnect channe ls that span the entire device . Each row of LABs is
served by a de di ca te d ro w interconnect . The ro w interconnect ca n drive
I/O pi ns and feed ot her LA Bs in the row. The c olumn inte rconnect routes
signals be twee n row s and can dri ve I/O pin s.
Row channels drive into the LAB or EAB local interconnect. The row
signal is buffered at every LAB or EAB to reduce t he effect of fan-out on
delay. A row channel can be driven by an LE or by one of three column
chan ne ls. T he se fo ur sig nals feed dual 4- to-1 mu ltip lex e rs tha t con ne ct t o
two specific row channels. T hese multiplexers, which are connected to
each LE, allow column channels to drive row channels even when all eight
LEs in a LAB drive the row interconnec t.
Each column of LABs or EABs is served by a dedicated c o l umn
interconnect. The column interconnect that serves the EABs has twice as
many channels as other column interconnects. The column interconnect
can t hen drive I/O pins or anoth er row’s int erconnect t o route the signals
to other LABs or EABs in the device. A signal from the column
interconnect, which can be either the output of a LE or an input from an
I/O pin, must be routed to the row interconnect before it can enter a LAB
or EAB. Each row channel that is driven by an IOE or EAB can drive one
specific column channel.
Access to row and column channels can be switched between LEs in
adjacent pairs of LABs. For example, a LE in one LAB can drive the row
and column channels normally driven by a particular LE in the adjacent
LAB in the same row, and vice versa. This flexibility enables routing
resource s to be used more efficiently (see Figure 13).

For improved routing, the row interconnect consists of a combination of
full-length and half-length channels. The full-length channels connect to
all LABs in a row; the half-length channels connect to the LABs in half of
the r ow. The EAB c an be driven by the h alf-length channels in th e left ha lf
of the row and b y th e fu ll-lengt h c hannel s. T he E AB d rive s out to the full-
length channels. In addition to providing a predictable, row-wide
inte r conn ect , t his architecture pro vid es inc reas ed r ou ting r e sourc es. T wo
neighboring LABs can be connected us ing a half-row channel, thereby
saving the other half of the channel for the other half of the row.
Table 7 summarizes the FastTrack Interconnect routing structure
resource s available in each FLEX 10KE device.
In addition t o gen eral-purpos e I/O pins, FLEX 10KE devices have six
ded icated in put pin s that pr ovide low -skew sig nal distr ibution across t he
device. These six inputs can be used for global clock, clear, preset, and
peripheral output enable and clock enable control signals. These signals
are available as control signals for all LABs and IOEs in the device. The
dedicated inputs can also be used as general-purpose data inputs because
they can feed the local interconnect of each LAB in the device.

An IOE contains a bidirectional I/O buffer and a register that can be used

or as an output registe r for data that requires fast clock-to-output

On a ll F LEX 10K E d e v ice s (except EPF 1 0K 50 E an d E PF10K200E de vices),
the input path from the I/O pad to the FastTrack Interconnect has a
programmable delay element that can be used to guarantee a zero hold
ti me. EPF10K50S and EPF10 K200S devices also support th is fe ature.
Depending on the placement of the IOE relative to what it is driving, the
desi gner may choo se to turn on the programm abl e delay to ens ure a zero
hold time or turn it off to minimize setup time. This feature is used to
reduc e setup time fo r complex pin-to-r e gis te r paths (e.g ., PCI desi gns ).
Each I OE se lects the clock, cle ar, clock enable, an d out put enable controls
from a network of I/O control signals called the periph e ral control bus.
The peripheral control bus uses high-speed drivers to minimize signal
skew across the device and provides up to 12 peripheral control signals
that can be allocated as follows:
■Up to eight output enable signals
■Up to six clock enable signals
■Up to two clock signals
■Up to two clear signals
If more than six clock enable or eight output enable signals are required,
each IOE on the device can be controlled by clock enable and output
enable signals drive n b y spec ific L Es. I n addi ti on to th e tw o clock sig na ls
available on the peripheral control bus, each IOE can use one of two
dedica te d clock pins . Ea ch perip her a l control signal can be driven by any
of the de dicated inp ut pins or the fir st LE of eac h LAB in a particular row.
In addition, a LE in a different row can drive a column interconnect, which
cause s a row interco nne ct to driv e t he pe riphe r al con tr ol s ign al. T he ch ip-
wide reset signal resets all IOE registers, overriding any other control
signals.
When a dedicated clock pin drives IOE registers, it can be inverted for all
IOEs in the device. All IOEs must use the same sense of the clock. For
example, if any IOE us es the inve rted clock, all IOEs must use the inverted
clock and no IOE can use the non-inverted clock. However, LEs can still
use the true or complement of the clock on a LAB-by-LAB basis.
The incoming signal may be inverted at the dedicated clock pin and will
drive all IOE s. For the t rue a nd c omple ment of a cl ock to be us ed t o drive
IOEs, dr ive it in to both globa l clock p ins. One global clo ck pin w ill supp ly
the true, and the other will supply the complement.
When the true and complement of a dedicated input drives IOE clocks,
two signals on the peripheral control bus are consumed, one for each
sense of th e clock.
Altera Corporation 33
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces Data Shee t
When dedicated inputs drive non-inverted and inverted peripheral clears,
clock enables, and output enables, two signals on the peripheral control
bus will be used.
Tables 8 and 9 lis t the sou rces for each p eriphera l control signal, a nd show
how the output enable, clock enable, clock, and clear signals share
12 peripheral control signals. The tables also show the rows that can drive
global signals.

Signals on the peripheral c ontrol bus can also drive the four global signals,
referred to as GLOBAL0 through GLOBAL3 in Tables 8 and 9. An intern ally
gener ated sig na l ca n d ri ve a gl obal signal , p ro viding the sa m e low -sk ew,
low-delay characteristics a s a s i gnal d riven b y an input pin. An LE driv es
the global signal by driving a row line that drives the peripheral bus,
which then drives the global signal. This feature is ideal for internally
generated clear or clock signals with high fan-out. However, internally
driven global signals offer no advantage over the general-purpose
interconnect for routing data signals. The dedicated input pin should be
driven to a know n logic state (such as ground) a nd no t be al lowed to float.
The chip-wide output enable pin is an active-high pin (DEV_OE) that can
be used to tri-state all pins on the device. This option can be set in the
Altera software. On EPF10K50E and EPF10K200E devices, the built-in I/O
pin pull-up resistors (which are active during configuration) are active
when the c hip-wide outpu t enable pin is assert ed. The reg isters in the IOE
can also be r eset by the chip-wi de re set pin.

SameFrame
Pin-Outs
FLEX 10KE devices support the SameFrame pin-out feature for
FineLine B GA pa ckages. Th e Same Fr ame p in-ou t feat ure is the
arrangement of balls on FineLine BGA packages such that the lower-ball-
count packages form a subset of the higher-ball-count packages.
SameFrame pin-outs provide the flexibility to migrate not only from
device to device within the same package, but also from one package to
anot her. A given printed cir cuit board (PCB) layout can support multipl e
device density/package combinations. For example, a single board layout
can support a ra nge of devices from an EPF10K30 E device in a 256-pin
FineLine BGA package to an EPF10K200S device in a 672-pin
FineLine BGA package.
The Altera software provides support to design PCBs with SameFrame
pin-out devices. De vices can be defined for present a nd fut ur e use . The
Altera software generates pin-outs describing how to lay out a board to
take advantage of this migration (see Figure 18).

C lockLock &
ClockBoost
Features
To support hig h-sp ee d desi gns, FL EX 10K E devices off er option al
ClockLock and ClockBoost circuitry containing a phase-locked loop (PLL)
used to increase design speed and reduce resource usage. The ClockLock
circu itry uses a sync hr oniz ing PL L that reduce s the clock d e lay a nd skew
within a device. This reduction minimizes clock-to-output and setup
times while main taining zero hold times . The Clock Boost circuitry, wh ich
provides a clock multiplier, allows the designer to enhance device area
efficiency by resource sharing within the device. The ClockBoost feature
allows the designer to distribute a low-speed clock and multiply that clock
on-device. Combined, the ClockLock and ClockBoost features provide
significant improvements in system performance and bandwidth.
All FLEX 10KE devices, except EPF10K50E and EPF10K200E devices,
support Clo ckLoc k and ClockBoos t circuit r y. EPF10K5 0S and
EPF10K200S devices support this circuitry. Devices that support Clock-
Lock a nd C loc kBoos t circuitry are distinguished with a n “ X ” suffix in the
ordering code; for instance, the EPF10K200SFC672-1X device supports
this circuit.
The ClockLock and ClockBoost features in FLEX 10 KE devices are
enabled through the Altera software. External devices are not required to
use these featur es. The output of the ClockLoc k and ClockB oost circuits is
no t available at any of the de vice pins.
The ClockL ock and Clock B oost ci rc uitry lock s ont o the rising edge of the
incoming clock. The circuit output can drive the clock inputs of registers
only; the generated clock cannot be gated or inverted.
The dedicated clock pin (GCLK1) supplies the cl ock to t he Clo ckLoc k a nd
ClockBoost circuitry. When the dedicated clock pin is driving the
ClockLock or ClockBoos t circuitr y, it c annot driv e elsewhere in the de vice.
For designs that require both a multiplied and non-multiplied clock, the
clock trace on the board can be connected to the GCLK1 pin. In th e
Altera software, the GCLK1 pin can feed both the ClockLock and
ClockBoost circuitry in the FLEX 10KE device. However, when both
circuits are used, the other clock pin cannot be used.

For the ClockLock and Cloc k Boost circuitry to function properly, the
incoming clock must meet certain requirements. If these specifications are
not met, the circuitry may not lock onto the incoming clock, which
generates an erroneous clock within the device. The clock generated by
the ClockLock and ClockBoost circuitry must also meet certain

Notes to table s:

PCI Pull-Up C lam ping Diode Option
FLEX 10KE devices have a pull-up clamping diode on every I/O,
dedicated input, and dedicated clock pin. PCI clamping diodes clamp the
signal to the VCCIO value and are required for 3.3-V PC I compliance.
Clamping diodes can also be used to limit overshoot in other systems.
Clamping diodes are controlled on a pin-by-pin basis. When VCCIO is
3.3 V, a pi n that has the c lamping diode option turned on can be driven b y
a 2.5-V or 3.3-V si gnal, but not a 5.0-V sign al. When VCCIO is 2.5 V, a pi n
that has the clamping diode option turned on can be driven by a 2.5-V
signal, but not a 3.3-V or 5.0-V signal. Additionally, a clamping diode can
be activated for a subset of pins, which would allow a device to bridge
between a 3.3-V PCI bus and a 5 .0-V d evic e.
Slew-Rate Control
The outp ut buffer in each IOE has an adjustab le output sle w rate tha t can
be configured for low-noise or high-speed performance. A slower slew
rate reduces system noise and adds a maximum delay of 4.3 ns. The fast
slew rate should be used for speed-critical outputs in systems that are
adequately protected against noise. Designers can specify the slew rate
pin-by-pin or ass ign a d e faul t sle w rate t o a ll pins on a device-wide b asi s.
The slow slew rate setting affects the falling edge of the output.
Open-Dr ain Out put Option
FLEX 10KE devices provide an optional open-drain output (electrically
equivalent to open-collector output ) for each I/O pin. This open-drain
output enables the device to provide system-level control signals (e.g.,
interrupt and write enable signals) that can be asserted by any of several
devices. It can also provide an additional wired-OR plane.
MultiVolt I/O Interface
The FLEX 10KE device architecture supports the MultiVolt I/O interface
feature, w hich a llows F LEX 10KE device s in a ll packa ges to i nter face with
systems of differing supply voltages. These devices have one set of VCC
pins for internal operation and input buffers (VCCINT), and another set for
I/O output drivers (VCCIO).
Altera Corporation 43
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces Data Shee t
The VCCINT pins must always be connected to a 2.5-V power supply.
With a 2.5-V VCCINT level, input voltages are compatible with 2.5-V, 3.3-
V, and 5.0-V in put s. T he VCCIO pins can be connect ed t o e ither a 2.5-V or
3.3-V power supply, depending on the output requirements. When the
VCCIO pins are connected to a 2.5-V power supply, the output leve ls are
com pa tib le wit h 2.5-V sy ste m s. When the VCCIO pins are connected to a
3.3-V power supply, the output high is at 3.3 V and is therefore compatible
with 3.3-V or 5.0-V systems. Device s operating with VCCIO levels higher
than 3.0 V achieve a faster timing delay of tOD2 instead of tOD1.
Table 14 summarizes FLEX 10KE MultiVolt I/O support.
Notes:
(1) T h e PCI clam pi ng diode mu s t be d isabled to drive an inp u t wit h vo lt ag es h igher
than VCCIO.
(2) Wh e n V CCIO = 3.3 V, a FLEX 10KE device can drive a 2.5-V device that has 3.3-V
tolerant inputs .
Open-drain output pins on FLEX 10KE devices (with a pull-up resistor to
the 5.0-V supply ) can drive 5.0-V CMOS input pins that req uire a VIH of
3.5 V. When the open-drain pin is active, it will drive low. When the pin is
inactive, the trace will be pulled up to 5.0 V by the resistor. The open-drain
pin will only drive low or tri-state; it will never drive high. The rise time
is depe ndent on the valu e of the pull-up re sistor and load impe dance . The
IOL current specification should be considered when selecting a pull-up
resistor.
Power Sequencing & Hot-Soc k eti ng
Beca use F LEX 10K E de vices can be used in a mixed -voltag e envi ronmen t,
they have been designed specifically to tolerate any possible power-up
sequence. The VCCIO and VCCINT power planes can be powered in any
order.
Signals can be dri ven into FLEX 10KE devices before and during power
up without damaging the device. Additionally, FLEX 10KE devices do not
drive out during power up. Once operating conditions are reached,
FLEX 10KE devices operate as specified by the user.

Generic Testing Each FLEX 10KE device is functionally tested. Complete testing of each
configurable static random access memory (SRAM) bit and all logic
functionality ensures 100% yield. AC test measurements for FLEX 10KE
device s ar e mad e under co nditions equivalen t to those shown in
Figure 21. Multiple test patterns can be used to configure devices during
all stages of the production flow .

Power supply transients can affect AC
measurements. Simultaneous transitions of
mu ltiple outputs should be av oided for
accurate measurement. Threshold tests
must not be performed under AC
conditions. Large-amplitude, fast-ground-
current transients normally occur as the
device outputs discharge the load
capa citanc es. When these tra nsients flow
throu gh the para sitic inductance betwee n
the device ground pin and the test system
groun d, signif icant reductions in
observable noise immunity can result.

Tim ing Model The continuous, high-performance FastTrack Interconnect routing
resources ensur e predictable performance and accurate simulation and
timing analysis. This predictable performance contrasts with that of
FPGAs, which use a seg mented connection scheme and ther ef ore have
un predi ctabl e per formance.
Device perf orm a nce c an b e e stima te d b y following the sig na l path fr om a
source, through the interconnect, to the destination. For example, the
registered perfo r mance between two LEs on the same r ow can b e
calculated by adding the following parameters:
■LE register clock-to-output delay (tCO)
■Interconnect delay (tSAMEROW)
■LE look-up table delay (tLUT)
■LE register setup time (tSU)
The rout ing delay depends on the placement of the source and destination
LEs. A more comp lex registered pat h may involve multiple combinatorial
LEs betwe en the sour ce and de st inat ion LEs.

(4) Operating conditions: VCCIO = 3.3 V.
(5) Because the RAM in the EAB is self-timed, this parameter can be ignored when the WE si gnal is regis tered .
(6) EAB macroparameters are internal parameters that can simplify predicting the behavior of an EAB at its boundary;
these parameters ar e c alcula t ed by summing sel ec t ed microparame t er s .
(7) These parameters are worst-case values for ty pical applications. Post-compilation timing simulation and timing
analysis are req ui r ed to de t ermine actual worst-case perfo r man c e.
(8) Contact Altera Applications for test circuit specifications and test conditions.
(9) This timing parameter is sample-tested only.
(10) This parameter is measured with the measurement and test conditions, including load, specified in the PCI Local
Bus Specification, revision 2.2.

Power
Consumption
The supply powe r (P) for FLEX 10KE devices can be calculated with the
following equation:
P = PINT + PIO = (ICCSTANDBY + ICCACTIVE) × VCC + PIO
The ICCACTIVE value depends on the switching frequency and the
application logic. This valu e i s ca lcu lat ed b ased on the amount of c ur rent
that each LE typically consumes. The PIO value, which depends on the
device output load characteristics and switching frequency, can be
calculated using the guidelines given in Application Note 7 4 (Ev aluating
Power for Altera Devices).
Compar ed to the r est of the device, the embed d ed array co nsumes a
negligible amount of power. Therefore, the embedded array can be
ignored when calculating supply current.
The ICCACTIVE value can be calculated with the following equation:
ICCACTIVE = K × fMAX × N × togLC ×
Where:
fMAX = Maximum operating frequency in MHz
N = Total number of LEs used in the device
togLC = Average percent of LEs toggling at each clock
(typically 12.5%)
K=Constant
Table 80 provides the constant (K) values for FLEX 10KE devices.
This calcul ation provides an ICC e stimate b ased on t ypi cal condit ions with
no output load. The actual ICC should be verified during operation
because this measurement is sensitive to the actual pattern in the device
and the environmental operating conditions.

To better reflect actual designs, the power model (and the constant K in
the power calculation equations) for continuous interconnect FLEX
devices assumes that LEs drive FastTrack Interconnect channels. In
contrast, the power model of segmented FPGAs assumes that all LEs drive
only one short interconnect segment. This assumption may lead to
inac cur at e resu lts whe n com pa red to measure d power consumption for
act ual de signs in segme nte d FPGAs.

frequency of FLEX 10KE devices.

Configuration &
Operation
The FLEX 10KE architecture supports several configuration schemes. This
section summarizes the device operating modes and available device
configuration schemes.
Operating Modes
The FLEX 10KE architecture uses SRAM configuration elements that
require configuration data to be loaded every time the circuit powers up.
The pr ocess of physically l oading the SRAM data in to the device is ca lle d
configuration. Before configuration, as VCC rise s, the device initiates a
Power-On Reset ( POR). This POR ev ent cl ears the de vice and prepar es it
for configuration. The FLEX 10KE POR time does not exceed 50 µs.
When configuring with a configuration device, refer to the respective
configurat ion device data sheet for POR timing information.

During initialization, which occurs immediately after configuration, the
device resets registers, enab les I/O pin s, and b egins to operate as a l ogic
device. The I/O pins are tri-stated during power-up, and before and
during configuration. Together, the configuration and initialization
pr ocesses ar e called comman d mode; nor mal device operation is called user
mode.
SRA M confi gura tion elem en ts allo w FL EX 10KE devices to be
reconfi gured in-circu it by loading new co nfiguration data into t he device.
Real-time reconfiguration is performed by forcing the device into
command mode with a device pin, loading different configuration data,
reinit iali zing the devic e, and resuming use r-mode operat ion. The entire
reconfiguration process requires less than 85 ms and can be used to
reconfig ure an entire system dynamically. In-field upgrades can be
performed by distributing new configuration files.
Before and during con fi gu ration, all I/O pins (excep t de di cated inputs,
clock, or configuration pins) are pulled high by a weak pull-up resistor.
Progra mming Files
Despite being function- and pin-compatible, FLEX 10KE devices are not
programming- or configuration file-compatible with FLEX 10K or
FLEX 10KA devices. A design therefo re must be recompil ed before it is
transfe rred from a FLEX 10K or FLEX 10KA device to an equivalent
FLEX 10KE device. This recompilation should be performed both to create
a new programming or configuration file and to check design timing in
FLEX 10K E devices, which ha s differ e nt timing character istics than
FLEX 1 0K or FLEX 10KA device s.
FLEX 10KE devices are generally pin-compatible with equivalent
FLEX 10KA devices. In some cases, FLEX 10KE device s have fewer I/O
pins than the equivalent FLEX 10KA devices. Table 81 shows which
FLEX 10KE devices have fewer I/O pins than equivalent FLEX 10KA
devices. However, power, ground, JTAG, and configuration pins are the
same on FLEX 10KA and FLEX 10KE devices, enabling migration from a
FLEX 10KA de sign to a FLEX 10KE design.
98 Altera Corporation
FLEX 10KE Embed d ed Prog ra mmable Logic De vi ces D ata Sheet
Addition ally, the Alte ra software offer s several feat ures that help pla n for
future device migration by preventing the use of conflicting I/O pins.
Configuration Schemes
The configu ration data for a FLEX 10KE device can be loaded with one of
five conf iguration schemes (s ee Table 82), ch osen on the basis of t he target
application. An EPC1, EPC2, or EPC16 configuration device, intelligent
controller, or the JTAG port can be used to control the configuration of a
FLEX 10KE device, allowing automatic configuration on system
power-up.
Multiple FLEX 10KE devices can be configured in any of the five
configuration schemes by connecting the configuration enable (nCE) and
configuration enable output (nCEO) pins on each device. Additional
FLEX 10K, FLEX 10KA, FLEX 10KE, an d FLEX 6000 devic es can be
configured in the same serial chain.
