USE ULTRA37000™  
FOR ALL NEW DESIGNS  
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 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.  
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  
• Advanced 0.65-micron CMOS EPROM technology to  
increase performance  
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.  
• 28-pin, 300-mil DIP, cerDIP or 28-pin HLCC, PLCC

Functional Description  
Available in a 28-pin, 300-mil DIP or windowed J-leaded  
ceramic chip carrier (HLCC), the CY7C344B represents the
