CY7C344

32-Macrocell MAX® EPLD

tional I/O pins communicate to one logic array block. In the

CY7C344 LAB there are 32 macrocells and 64 expander prod-

uct terms. When an I/O macrocell is used as an input, two

expanders are used to create an input path. Even if all of the

I/O pins are driven by macrocell registers, there are still 16

“buried” registers available. All inputs, macrocells, and I/O pins

are interconnected within the LAB.

Features

• High-performance, high-density replacement for TTL,

74HC, and custom logic

• 32 macrocells, 64 expander product terms in one LAB

• 8 dedicated inputs, 16 I/O pins

• 0.8-micron double-metal CMOS EPROM technology

The speed and density of the CY7C344 makes it a natural for

all types of applications. With just this one device, the designer

can implement complex state machines, registered logic, and

combinatorial “glue” logic, without using multiple chips. This

architectural flexibility allows the CY7C344 to replace multi-

chip TTL solutions, whether they are synchronous, asynchro-

nous, combinatorial, or all three.

Functional Description

Available in a 28-pin, 300-mil DIP or windowed J-leaded ce-

ramic chip carrier (HLCC), the CY7C344 represents the dens-

est EPLD of this size. Eight dedicated inputs and 16 bidirec-
