CY7C344B 32-Macrocell EPLD • 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 • Advanced 0.65-micron CMOS EPROM technology to increase performance • 28-pin, 300-mil DIP, cerDIP or 28-pin HLCC, PLCC package Functional Description Available in a 28-pin, 300-mil DIP or windowed J-leaded ceramic chip carrier HLCC , the CY7C344B represents the densest EPLD of this size. Eight dedicated inputs and 16 bidirectional I/O pins communicate to one logic array block. In the CY7C344B LAB there are 32 macrocells and 64 expander product 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. The speed and density of the CY7C344B 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 CY7C344B to replace multichip TTL solutions, whether they are synchronous, asynchronous, combinatorial, or all three.
