com 44B CY7C344 32-Macrocell MAX® EPLD 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 • 28-pin, 300-mil DIP, cerDIP or 28-pin HLCC, PLCC package tional 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...
