Functional Description

The CY7C375i is an In-System Reprogrammable Complex

Programmable Logic Device (CPLD) and is part of the

FLASH370i™ family of high-density, high-speed CPLDs. Like

all members of the FLASH370i family, the CY7C375i is de-

signed to bring the ease of use and high performance of the

22V10 to high-density PLDs.

Like all of the UltraLogic™ FLASH370i devices, the CY7C375i

is electrically erasable and In-System Reprogrammable (ISR),

which si mp lifies both design and manu fac turi ng f low s the reby

reducing costs. The Cypress ISR function is implemented

through a JTAG serial interface. Data is shifted in and out

thro ugh the S DI and S DO pins. The ISR int erfac e is en abled

using the programming voltage pin (ISREN). Additionally, be-

cause of the s uperior ro utability of the FLASH370i d evices, ISR

often allows users to change existing logic designs while si-

multaneously fixing pinout assignments.

CY7C375i

Document #: 38-03029 Rev. ** Page 4 of 17

Functional Description (continued)

The 128 macrocells in the CY7C375i are divided between

eight logic blocks. Each logic block includes 16 macrocells, a

72 x 86 product term array, and an intelligent product term

allocator.

The logic blocks in the FLASH370i architecture are connected

with an extremely fast and predictable routing resource—the

Programmable Interconnect Matrix (PIM). The PIM brings flex-

ibility, routability, speed, and a uniform delay to the intercon-

nect.

Like all members of the FLASH370i family , the CY7C375i is rich

in I/O resources. Every macrocell in the device features an

assoc iated I/O pin, res ulting in 128 I/O pi ns on the CY7C375 i.

In addition, there is one dedicated input and four input/clock

pins.

Finally, the CY7C375i features a very simple timing model.

Unlike other high-density CPLD architectures, there are no

hidden speed delays such as fanout effects, interconnect de-

lays, or expander delays. Regardless of the number of re-

sources used or the ty pe of applic ation, the tim ing paramete rs

on the CY7C375i remain the same.

Logic Block

The number of logic blocks distinguishes the members of the

FLASH370i family. The CY7C375i includes eight logic blocks.

Each logic block is constructed of a product term array, a prod-

uct term allocator, and 16 macrocells.

Product Term Array

The product term array in the FLASH370i lo gic bl ock inc ludes

36 inputs from the PIM and outputs 86 product terms to the

product term allocator. The 36 inputs from the PIM are avail-

able in both positive and negative polarity, making the overall

array size 72 x 86. This large array in each logic block allows

for very c omplex fun ctions to be im plemented in single pas ses

through the device.

Product Term Allocator

The product term allocator is a dynamic, configurable resource

that shifts product terms to macrocells that require them. Any

number of product terms between 0 and 16 inclusive can be

assigned to any of the logic block macrocells (this is called

product term steering). Furthermore, product terms can be

shared among multiple macrocells. This means that product

terms tha t are comm on to more than one ou tput ca n be imple-

mented in a single product term. Product term steering and

product term sharing help to increase the effective density of

the FLASH37 0i PLD s. Note that produc t term a lloca tion is han-

dled by software and is invisible to the user.

I/O Macrocell

Each of the macrocells on the CY7C375i has a separate I/O

pin as sociated with it. T he in put to the m ac roc ell is t he sum of

betwee n 0 and 16 produc t terms from the product term alloca-

tor. The macrocell includes a register that can be optionally

bypassed, polarity control over the input sum-term, and four

global clocks to trigger the register. The macrocell also fea-

tures a s ep arat e fe edback path to the PIM so that the reg is ter

can be buried if the I/O pin is used as an input.

Programmable Interconnect Matrix

The Programmable Interconnect Matrix (PIM) connects the

eight logic blocks on the CY7C375i to the inputs and to each

other. All inputs (including feedbacks) travel through the PIM.

There is no speed penalty incurred by signals traversing the

PIM.

Programming

For an overview of ISR programming, refer to the FLASH370i

Family data sheet and for ISR cable and software specifica-

tions, refer to ISR data sheets. For a detailed description of

ISR capabilities, refer to the Cypress application note, “An In-

troduction to In System Reprogramming with FLASH370i.”

PCI Compliance

The FLASH370i family of CMOS CPLDs are fully compliant with

the PCI Local Bus Specification published by the PCI Special

Interest Group. The simple and predictable timing model of

FLASH370i e nsures compl iance with the PC I AC specificat ions

independent of the design. On the other hand, in CPLD and

FPGA architectures without simple and predictable timing, PCI

compliance is dependent upon routing and product term

distribution.

3.3V or 5.0V I/O operation

The FLASH370i family can be configured to operate in both

3.3V and 5 .0V systems . All devices have two sets of VCC pins:

one set, VCCINT, for internal operation and input buffers, and

another set, VCCIO, for I/O output drivers. VCCINT pins must

always be connected to a 5.0V power supply. However, the

VCCIO pins may be connected to either a 3.3V or 5.0V power

supply, depending on the output requirements. When VCCIO

pins are connected to a 5.0V sourc e, the I/O volta ge levels a re

compat ible w ith 5.0 V syst ems. W hen VCCIO pins are connec t-

ed to a 3.3V source, the input voltage levels are compatible

with bot h 5.0V and 3.3V sys tems, while the ou tput voltage lev -

els are compatible with 3.3V systems. There will be an addi-

tional ti ming delay o n all output b uffers wh en operating i n 3.3V

I/O mode. The added flexibility of 3.3V I/O capability is avail-

able in commercial and industrial temperature ranges.

Bus Hold Capabilities on all I/Os and Dedicated Inputs

In additi on to ISR capa bility, a new feature ca lled bus-h old has

been added to all FLASH370i I/Os and dedicated input pins.

Bus-hold, which is an improved version of the popular internal

pull-up re sisto r, is a wea k latch co nnect ed to the pin that doe s

not degrade the device’s performance. As a latch, bus-hold

recalls the last state of a pin when it is three-stated, thus re-

ducing system noise in bus-interface applications. Bus-hold

addition ally al lows u nused d evice p ins to re main un conne cted

on the b oard, whi ch is partic ularly us eful during p rototy ping as

designers can route new signals to the device without cutting

trace connections to VCC or GND.

Notes:

3. See the last page of this specification for Group A subgroup testing information.

4. If VCCIO is not specified, the device can be operating in either 3.3V or 5V I/O mode; VCC=VCCINT.

5. IOH = –2 mA, IOL = 2 mA for SDO.

6. When the I/O is three-stated, the bus-hold circuit can weakly pull the I/O to a maximum of 4.0V if no leakage current is allowed. This voltage is lowered significantly

by a small leakage current. Note that all I/Os are three-stated during ISR programming. Refer to the application note “Understanding Bus Hold” for addit ional

information.

7. These are absolute values with respect to device ground. All overshoots due to system or tester noise are included.

8. Not more than one output should be tested at a time. Duration of the short circuit should not exceed 1 second. VOUT = 0.5V has been chosen to avoid test

problems caused by tester ground degradation.

9. Tested initially and after any design or process changes that may affect these parameters.

10. Measured with 16-bit counter programmed into each logic block.

11. CI/O for dedicated inputs, and for I/O pins with JTAG functionality is 12 pF,and for the ISREN pin is 15 pF Max.

Notes:

13. All AC parameters are measured with 16 outputs switching and 35-pF AC Test Load.

14. This specification is intended to guarantee interface compatibility of the other members of the CY7C370i family with the CY7C375i. This specification is met

for the devices operating at the same ambient temperature and at the same power supply voltage.
