Like all members of the FLASH370 family, the CY7C374 is designed to bring the ease of use and high performance of the 22V10 to high-density CPLDs. The 128 macrocells in the CY7C374 are divided between eight logic blocks. Each logic block includes 16 macrocells, a 72 x 86 product term array, and an intelligent product term allocator. The logic blocks in the FLASH370 architecture are connected with an extremely fast and predictable routing resource--the Programmable Interconnect Matrix (PIM). The PIM brings flexibility, routability, speed, and a uniform delay to the interconnect. The CY7C374 is a register intensive 128-Macrocell CPLD. Every two macrocells in the device feature an associated I/O pin, resulting in 64 I/O pins on the CY7C374. In addition, there are two dedicated inputs and four input/clock pins.
