UltraLogic 64-Macrocell Flash CPLD
Available in 84-pin PLCC and 100-pin TQFP packages
Features
Pin compatible with the CY7C374i
64 macrocells in four logic blocks
64 I/O pins Functional Description
5 dedicated inputs including 4 clock pins
The CY7C373i is an In-System Reprogrammable Complex
In-System Reprogrammable (ISR) Flash Programmable Logic Device (CPLD) and is part of the
technology FLASH370i family of high-density, high-speed CPLDs. Like
all members of the FLASH370i family, the CY7C373i is
JTAG interface
designed to bring the ease of use and high performance of the
Bus Hold capabilities on all I/Os and dedicated inputs
22V10, as well as PCI Local Bus Specification support, to
high-density CPLDs.
No hidden delays
Like all of the UltraLogic FLASH370i devices, the CY7C373i
High speed
is electrically erasable and In-System Reprogrammable (ISR),
f = 125 MHz
MAX
which simplifies both design and manufacturing flows, thereby
t = 10 ns reducing costs. The Cypress ISR function is implemented
PD
through a JTAG serial interface. Data is shifted in and out
t = 5.5 ns
S
through the SDI and SDO pins.The ISR interface is enabled
t = 6.5 ns
using the programming voltage pin (ISR ). Additionally,
CO
EN
because of the superior routability of the FLASH370i devices,
Fully PCI compliant
ISR often allows users to change existing logic designs while
3.3V or 5.0V I/O operation
simultaneously fixing pinout assignments.
