Functional Description
The CY7C374i is an In-System Reprogrammable Complex
Programmable Logic Device (CPLD) and is part of the
F
LASH
370i鈩?family of high-density, high-speed CPLDs. Like
all members of the F
LASH
370i family, the CY7C374i is de-
signed to bring the ease of use as well as PCI Local Bus Spec-
ification support and high performance of the 22V10 to
high-density CPLDs.
Like all of the UltraLogic鈩?F
LASH
370i devices, the CY7C374i
is electrically erasable and In-System Reprogrammable (ISR),
which simplifies both design and manufacturing flows thereby
reducing costs. The Cypress ISR function is implemented
through a JTAG serial interface. Data is shifted in and out
through the SDI and SDO pin. The ISR interface is enabled
using the programming voltage pin (ISR
EN
). Additionally, be-
cause of the superior routability of the F
LASH
370i devices, ISR
often allows users to change existing logic designs while si-
multaneously fixing pinout assignments.
The 128 macrocells in the CY7C374i 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.
