CY7C344B  
32-Macrocell MAX® EPLD  
sents the 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  
(CY7C344)  
The speed and density of the CY7C344/CY7C344B makes it  
a natural for all types of applications. With just this one device,  
the designer can implement complex state machines, regis-  
tered logic, and combinatorial “glue” logic, without using mul-  
tiple chips. This architectural flexibility allows the  
CY7C344/CY7C344B to replace multichip TTL solutions,  
whether they are synchronous, asynchronous, combinatorial,  
or all three.  
• Advanced 0.65-micron CMOS EPROM technology to  
increase performance (CY7C344B)  
• 28-pin 300-mil DIP, cerDIP or 28-pin HLCC, PLCC  
package
