CY7C342B
128-Macrocell MAX
廬
EPLD
Features
鈥?128 macrocells in eight logic array blocks (LABs)
鈥?Eight dedicated inputs, 52 bidirectional I/O pins
鈥?Programmable interconnect array
鈥?Advanced 0.65-micron CMOS technology to increase
performance
鈥?Available in 68-pin HLCC, PLCC, and PGA packages
100% user-configurable, allowing the device to accommodate
a variety of independent logic functions.
The 128 macrocells in the CY7C342B are divided into eight
LABs, 16 per LAB. There are 256 expander product terms, 32
per LAB, to be used and shared by the macrocells within each
LAB.
Each LAB is interconnected with a programmable interconnect
array, allowing all signals to be routed throughout the chip.
The speed and density of the CY7C342B allows it to be used in a
wide range of applications, from replacement of large amounts of
7400-series TTL logic, to complex controllers and multifunction
chips. With greater than 25 times the functionality of 20-pin PLDs,
the CY7C342B allows the replacement of over 50 TTL devices.
By replacing large amounts of logic, the CY7C342B reduces board
space, part count, and increases system reliability.
Functional Description
The CY7C342B is an Erasable Programmable Logic Device
(EPLD) in which CMOS EPROM cells are used to configure
logic functions within the device. The MAX
