CY7C344B

32-Macrocell MAX^®EPLD

densest EPLD of this size. Eight dedicated inputs and 16

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

the CY7C344 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.

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

multichip TTL solutions, whether they are synchronous,

asynchronous, combinatorial, or all three.
