MAX 7000A devices use CMOS EEPROM cells to implement logic
functions. The user-configurable MAX 7000A architecture accommodates
a variety of independent combinatorial and sequential logic functions.
The devices can be reprogrammed for quick and efficient iterations
during design development and debug cycles, and can be programmed
and erased up to 100 times.
MAX 7000A devices contain from 32 to 512 macrocells that are combined
into groups of 16 macrocells, called logic array blocks (LABs). Each
macrocell has a programmable-
AND
/fixed-
OR
array and a configurable
register with independently programmable clock, clock enable, clear, and
preset functions. To build complex logic functions, each macrocell can be
supplemented with both shareable expander product terms and high-
speed parallel expander product terms, providing up to 32 product terms
per macrocell.

MAX 7000A Programmable Logic Device Data Sheet
MAX 7000A devices provide programmable speed/power optimization.
Speed-critical portions of a design can run at high speed/full power,
while the remaining portions run at reduced speed/low power. This
speed/power optimization feature enables the designer to configure one
or more macrocells to operate at 50
%
or lower power while adding only a
nominal timing delay. MAX 7000A devices also provide an option that
reduces the slew rate of the output buffers, minimizing noise transients
when non-speed-critical signals are switching. The output drivers of all
MAX 7000A devices can be set for 2.5 V or 3.3 V, and all input pins are
2.5-V, 3.3-V, and 5.0-V tolerant, allowing MAX 7000A devices to be used
in mixed-voltage systems.
MAX 7000A devices are supported by Altera development systems,
which are integrated packages that offer schematic, text—including
VHDL, Verilog HDL, and the Altera Hardware Description Language
(AHDL)—and waveform design entry, compilation and logic synthesis,
simulation and timing analysis, and device programming. The software
provides EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL, and other
interfaces for additional design entry and simulation support from other
industry-standard PC- and UNIX-workstation-based EDA tools. The
software runs on Windows-based PCs, as well as Sun SPARCstation, and
HP 9000 Series 700/800 workstations.

Macrocells
MAX 7000A macrocells can be individually configured for either
sequential or combinatorial logic operation. The macrocells consist of
three functional blocks: the logic array, the product-term select matrix,
and the programmable register. Figure 2 shows a MAX 7000A macrocell.
Figure 2. MAX 7000A Macrocell
Combinatorial logic is implemented in the logic array, which provides
five product terms per macrocell. The product-term select matrix allocates
these product terms for use as either primary logic inputs (to the OR and
XOR gates) to implement combinatorial functions, or as secondary inputs
to the macrocell’s register preset, clock, and clock enable control
functions.
Two kinds of expander product terms (“expanders”) are available to
supplement macrocell logic resources:
■Shareable expanders, which are inverted product terms that are fed
back into the logic array
■Parallel expanders, which are product terms borrowed from adjacent
macrocells
The Altera development system automatically optimizes product-term
allocation according to the logic requirements of the design.

MAX 7000A Programmable Logic Device Data Sheet
For registered functions, each macrocell flipflop can be individually
programmed to implement D, T, JK, or SR operation with programmable
clock control. The flipflop can be bypassed for combinatorial operation.
During design entry, the designer specifies the desired flipflop type; the
Altera software then selects the most efficient flipflop operation for each
registered function to optimize resource utilization.
Each programmable register can be clocked in three different modes:
■Global clock signal. This mode achieves the fastest clock-to-output
performance.
■Global clock signal enabled by an active-high clock enable. A clock
enable is generated by a product term. This mode provides an enable
on each flipflop while still achieving the fast clock-to-output
performance of the global clock.
■Array clock implemented with a product term. In this mode, the
flipflop can be clocked by signals from buried macrocells or I/O pins.
Two global clock signals are available in MAX 7000A devices. As shown
in Figure 1, these global clock signals can be the true or the complement
of either of the global clock pins, GCLK1 or GCLK2.
Each register also supports asynchronous preset and clear functions. As
shown in Figure 2, the product-term select matrix allocates product terms
to control these operations. Although the product-term-driven preset and
clear from the register are active high, active-low control can be obtained
by inverting the signal within the logic array. In addition, each register
clear function can be individually driven by the active-low dedicated
global clear pin (GCLRn). Upon power-up, each register in a MAX 7000AE
device may be set to either a high or low state. This power-up state is
specified at design entry. Upon power-up, each register in EPM7128A and
EPM7256A devices are set to a low state.
All MAX 7000A I/O pins have a fast input path to a macrocell register.
This dedicated path allows a signal to bypass the PIA and combinatorial
logic and be clocked to an input D flipflop with an extremely fast (as low
as 2.5 ns) input setup time.
10 Altera Corporation
MAX 7000A Programmable Logic Device Data Sheet
Expander Product Terms
Although most logic functions can be implemented with the five product
terms available in each macrocell, more complex logic functions require
additional product terms. Another macrocell can be used to supply the
required logic resources. However, the MAX 7000A architecture also
offers both shareable and parallel expander product terms that provide
additional product terms directly to any macrocell in the same LAB. These
expanders help ensure that logic is synthesized with the fewest possible
logic resources to obtain the fastest possible speed.
Shareable Expanders
Each LAB has 16 shareable expanders that can be viewed as a pool of
uncommitted single product terms (one from each macrocell) with
inverted outputs that feed back into the logic array. Each shareable
expander can be used and shared by any or all macrocells in the LAB to
build complex logic functions. A small delay (tSEXP) is incurred when
shareable expanders are used. Figure 3 shows how shareable expanders
can feed multiple macrocells.
Figure 3. MAX 7000A Shareable Expanders
Shareable expanders can be shared by any or all macrocells in an LAB.

MAX 7000A Programmable Logic Device Data Sheet
Parallel Expanders
Parallel expanders are unused product terms that can be allocated to a
neighboring macrocell to implement fast, complex logic functions.
Parallel expanders allow up to 20 product terms to directly feed the
macrocell OR logic, with five product terms provided by the macrocell and
15 parallel expanders provided by neighboring macrocells in the LAB.
The compiler can allocate up to three sets of up to five parallel expanders
to the macrocells that require additional product terms. Each set of five
parallel expanders incurs a small, incremental timing delay (tPEXP). For
example, if a macrocell requires 14 product terms, the compiler uses the
five dedicated product terms within the macrocell and allocates two sets
of parallel expanders; the first set includes five product terms, and the
second set includes four product terms, increasing the total delay by
2 × tPEXP.
Two groups of eight macrocells within each LAB (e.g., macrocells 1
through 8 and 9 through 16) form two chains to lend or borrow parallel
expanders. A macrocell borrows parallel expanders from lower-
numbered macrocells. For example, macrocell 8 can borrow parallel
expanders from macrocell 7, from macrocells 7 and 6, or from macrocells
7, 6, and 5. Within each group of eight, the lowest-numbered macrocell
can only lend parallel expanders, and the highest-numbered macrocell
can only borrow them. Figure 4 shows how parallel expanders can be
borrowed from a neighboring macrocell.

Unused product terms in a macrocell can be allocated to a neighboring macrocell.
Programmable Interconnect Array
Logic is routed between LABs on the PIA. This global bus is a
programmable path that connects any signal source to any destination on
the device. All MAX 7000A dedicated inputs, I/O pins, and macrocell
outputs feed the PIA, which makes the signals available throughout the
entire device. Only the signals required by each LAB are actually routed
from the PIA into the LAB. Figure 5 shows how the PIA signals are routed
into the LAB. An EEPROM cell controls one input to a 2-input AND gate,
which selects a PIA signal to drive into the LAB.

While the routing delays of channel-based routing schemes in masked or
FPGAs are cumulative, variable, and path-dependent, the MAX 7000A
PIA has a predictable delay. The PIA makes a design’s timing
performance easy to predict.
I/O Control Blocks
The I/O control block allows each I/O pin to be individually configured
for input, output, or bidirectional operation. All I/O pins have a tri-state
buffer that is individually controlled by one of the global output enable
signals or directly connected to ground or VCC. Figure 6 shows the I/O
control block for MAX 7000A devices. The I/O control block has 6 or
10 global output enable signals that are driven by the true or complement
of two output enable signals, a subset of the I/O pins, or a subset of the
I/O macrocells.

When the tri-state buffer control is connected to ground, the output is
tri-stated (high impedance) and the I/O pin can be used as a dedicated
input. When the tri-state buffer control is connected to VCC, the output is
enabled.
The MAX 7000A architecture provides dual I/O feedback, in which
macrocell and pin feedbacks are independent. When an I/O pin is
configured as an input, the associated macrocell can be used for buried
logic.

SameFrame
Pin-Outs
MAX 7000A devices support the SameFrame pin-out feature for
FineLine BGA packages. The SameFrame pin-out feature 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
another. A given printed circuit board (PCB) layout can support multiple
device density/package combinations. For example, a single board layout
can support a range of devices from an EPM7128AE device in a 100-pin
FineLine BGA package to an EPM7512AE device in a 256-pin
FineLine BGA package.
The Altera design software provides support to design PCBs with
SameFrame pin-out devices. Devices can be defined for present and
future use. The software generates pin-outs describing how to lay out a
board to take advantage of this migration (see Figure 7).

In-System
Programma-
bility
MAX 7000A devices can be programmed in-system via an industry-
standard 4-pin IEEE Std. 1149.1 (JTAG) interface. ISP offers quick, efficient
iterations during design development and debugging cycles. The
MAX 7000A architecture internally generates the high programming
voltages required to program EEPROM cells, allowing in-system
programming with only a single 3.3-V power supply. During in-system
programming, the I/O pins are tri-stated and weakly pulled-up to
eliminate board conflicts. The pull-up value is nominally 50 kΩ.
MAX 7000AE devices have an enhanced ISP algorithm for faster
programming. These devices also offer an ISP_Done bit that provides safe
operation when in-system programming is interrupted. This ISP_Done
bit, which is the last bit programmed, prevents all I/O pins from driving
until the bit is programmed. This feature is only available in EPM7032AE,
EPM7064AE, EPM7128AE, EPM7256AE, and EPM7512AE devices.
ISP simplifies the manufacturing flow by allowing devices to be mounted
on a PCB with standard pick-and-place equipment before they are
programmed. MAX 7000A devices can be programmed by downloading
the information via in-circuit testers, embedded processors, the Altera
MasterBlaster serial/USB communications cable, ByteBlasterMV parallel
port download cable, and BitBlaster serial download cable. Programming
the devices after they are placed on the board eliminates lead damage on
high-pin-count packages (e.g., QFP packages) due to device handling.
MAX 7000A devices can be reprogrammed after a system has already
shipped to the field. For example, product upgrades can be performed in
the field via software or modem.
In-system programming can be accomplished with either an adaptive or
constant algorithm. An adaptive algorithm reads information from the
unit and adapts subsequent programming steps to achieve the fastest
possible programming time for that unit. A constant algorithm uses a pre-
defined (non-adaptive) programming sequence that does not take
advantage of adaptive algorithm programming time improvements.
Some in-circuit testers cannot program using an adaptive algorithm.
Therefore, a constant algorithm must be used. MAX 7000AE devices can
be programmed with either an adaptive or constant (non-adaptive)
algorithm. EPM7128A and EPM7256A device can only be programmed
with an adaptive algorithm; users programming these two devices on
platforms that cannot use an adaptive algorithm should use EPM7128AE
and EPM7256AE devices.
The Jam Standard Test and Programming Language (STAPL), JEDEC
standard JESD 71, can be used to program MAX 7000A devices with in-

JTAG Instruction Description
SAMPLE/PRELOAD Allows a snapshot of signals at the device pins to be captured and examined during
normal device operation, and permits an initial data pattern output at the device pins
EXTEST Allows the external circuitry and board-level interconnections to be tested by forcing a
test pattern at the output pins and capturing test results at the input pins
BYPASS Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST
data to pass synchronously through a selected device to adjacent devices during normal
device operation

MAX 7000A Programmable Logic Device Data Sheet
Programmable
Speed/Power
Control
MAX 7000A devices offer a power-saving mode that supports low-power
operation across user-defined signal paths or the entire device. This
feature allows total power dissipation to be reduced by 50% or more
because most logic applications require only a small fraction of all gates to
operate at maximum frequency.
The designer can program each individual macrocell in a MAX 7000A
device for either high-speed (i.e., with the Turbo BitTM option turned on)
or low-power operation (i.e., with the Turbo Bit option turned off). As a
result, speed-critical paths in the design can run at high speed, while the
remaining paths can operate at reduced power. Macrocells that run at low
power incur a nominal timing delay adder (tLPA) for the tLAD, tLAC, tIC,
tEN, tSEXP, tACL, and tCPPW parameters.
Output
Configuration
MAX 7000A device outputs can be programmed to meet a variety of
system-level requirements.
MultiVolt I/O Interface
The MAX 7000A device architecture supports the MultiVolt I/O interface
feature, which allows MAX 7000A devices to connect to systems with
differing supply voltages. MAX 7000A devices in all packages can be set
for 2.5-V, 3.3-V, or 5.0-V I/O pin operation. These devices have one set of
VCC pins for internal operation and input buffers (VCCINT), and another
set for I/O output drivers (VCCIO).
The VCCIO pins can be connected to either a 3.3-V or 2.5-V power supply,
depending on the output requirements. When the VCCIO pins are
connected to a 2.5-V power supply, the output levels are compatible with
2.5-V systems. 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. Devices operating with VCCIO levels lower than 3.0 V
incur a slightly greater timing delay of tOD2 instead of tOD1. Inputs can
always be driven by 2.5-V, 3.3-V, or 5.0-V signals.
Table 9 describes the MAX 7000A MultiVolt I/O support.

MAX 7000A Programmable Logic Device Data Sheet
Open-Drain Output Option
MAX 7000A devices provide an optional open-drain (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. This
output can also provide an additional wired-OR plane.
Open-drain output pins on MAX 7000A devices (with a pull-up resistor to
the 5.0-V supply) can drive 5.0-V CMOS input pins that require a high
VIH. When the open-drain pin is active, it will drive low. When the pin is
inactive, the resistor will pull up the trace to 5.0 V to meet CMOS VOH
requirements. The open-drain pin will only drive low or tri-state; it will
never drive high. The rise time is dependent on the value of the pull-up
resistor and load impedance. The IOL current specification should be
considered when selecting a pull-up resistor.
Programmable Ground Pins
Each unused I/O pin on MAX 7000A devices may be used as an
additional ground pin. In EPM7128A and EPM7256A devices, utilizing
unused I/O pins as additional ground pins requires using the associated
macrocell. In MAX 7000AE devices, this programmable ground feature
does not require the use of the associated macrocell; therefore, the buried
macrocell is still available for user logic.
Slew-Rate Control
The output buffer for each MAX 7000A I/O pin has an adjustable output
slew rate that can be configured for low-noise or high-speed performance.
A faster slew rate provides high-speed transitions for high-performance
systems. However, these fast transitions may introduce noise transients
into the system. A slow slew rate reduces system noise, but adds a
nominal delay of 4 to 5 ns. When the configuration cell is turned off, the
slew rate is set for low-noise performance. Each I/O pin has an individual
EEPROM bit that controls the slew rate, allowing designers to specify the
slew rate on a pin-by-pin basis. The slew rate control affects both the
rising and falling edges of the output signal.
Altera Corporation 23
MAX 7000A Programmable Logic Device Data Sheet
Power
Sequencing &
Hot-Socketing
Because MAX 7000A devices can be used in a mixed-voltage
environment, 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 driven into MAX 7000AE devices before and during power-
up (and power-down) without damaging the device. Additionally,
MAX 7000AE devices do not drive out during power-up. Once operating
conditions are reached, MAX 7000AE devices operate as specified by the
user.
Design Security All MAX 7000A devices contain a programmable security bit that controls
access to the data programmed into the device. When this bit is
programmed, a design implemented in the device cannot be copied or
retrieved. This feature provides a high level of design security because
programmed data within EEPROM cells is invisible. The security bit that
controls this function, as well as all other programmed data, is reset only
when the device is reprogrammed.
Generic Testing MAX 7000A devices are fully tested. Complete testing of each
programmable EEPROM bit and all internal logic elements ensures 100%
programming yield. AC test measurements are taken under conditions
equivalent to those shown in Figure 9. Test patterns can be used and then
erased during early stages of the production flow.

Power supply transients can affect AC
measurements. Simultaneous transitions
of multiple outputs should be avoided 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
capacitances. When these transients flow
through the parasitic inductance between
the device ground pin and the test system
ground, significant reductions in
observable noise immunity can result.

outputs. Numbers without brackets are for
3.3-V outputs.

Notes to tables:
(1) These values are specified under the recommended operating conditions shown in Table 11 on page 24.
(2) These values are specified for a PIA fan-out of one LAB (16 macrocells). For each additional LAB fan-out in these
devices, add an additional 0.1 ns to the PIA timing value.
(3) This minimum pulse width for preset and clear applies for both global clear and array controls. The tLPA parameter
must be added to this minimum width if the clear or reset signal incorporates the tLAD parameter into the signal
path.
(4) This parameter is measured with a 16-bit loadable, enabled, up/down counter programmed into each LAB.
(5) Operating conditions: VCCIO = 2.5 ± 0.2 V for commercial and industrial use.
(6) The tLPA parameter must be added to the tLAD, tLAC, tIC, tEN, tSEXP, tACL, and tCPPW parameters for macrocells
running in low-power mode.
Power
Consumption
Supply power (P) versus frequency (fMAX, in MHz) for MAX 7000A
devices is calculated with the following equation:
P = PINT + PIO = ICCINT × VCC + PIO
The PIO value, which depends on the device output load characteristics
and switching frequency, can be calculated using the guidelines given in
Application Note 74 (Evaluating Power for Altera Devices).
The ICCINT value depends on the switching frequency and the application
logic. The ICCINT value is calculated with the following equation:
ICCINT =
(A × MCTON) + [B × (MCDEV – MCTON)] + (C × MCUSED × fMAX × togLC)
tRD Register delay 1.6 2.0 2.7 3.2 ns

The parameters in this equation are:
MCTON = Number of macrocells with the Turbo Bit option turned
on, as reported in the MAX+PLUS II Report File (.rpt)
MCDEV = Number of macrocells in the device
MCUSED = Total number of macrocells in the design, as reported in
the Report File
fMAX = Highest clock frequency to the device
togLC = Average percentage of logic cells toggling at each clock
(typically 12.5%)
A, B, C = Constants, shown in Table 28
This calculation provides an ICC estimate based on typical conditions
using a pattern of a 16-bit, loadable, enabled, up/down counter in each
LAB with no output load. Actual ICC should be verified during operation
because this measurement is sensitive to the actual pattern in the device
and the environmental operating conditions.
