CY7C341B
192-Macrocell MAX® EPLD
Features
• 192 macrocells in 12 logic array blocks (LABs)
• Eight dedicated inputs, 64 bidirectional I/O pins
• Advanced 0.65-micron CMOS technology to increase
performance
• Programmable interconnect array
• 384 expander product terms
• Available in 84-pin HLCC, PLCC, and PGA packages
Functional Description
The CY7C341B is an Erasable Programmable Logic Device
(EPLD) in which CMOS EPROM cells are used to configure
logic functions within the device. The MAX® architecture is
100% user-configurable, allowing the devices to accom-
modate a variety of independent logic functions.
The 192 macrocells in the CY7C341B are divided into 12 Logic
Array Blocks (LABs), 16 per LAB. There are 384 expander
product terms, 32 per LAB, to be used and shared by the
Selection Guide

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 CY7C341B 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 37 times the functionality
of 20-pin PLDs, the CY7C341B allows the replacement of over
75 TTL devices. By replacing large amounts of logic, the
CY7C341B reduces board space, part count, and increases
system reliability.
Each LAB contains 16 macrocells. In LABs A, F, G, and L, 8
macrocells are connected to I/O pins and eight are buried,
while for LABs B, C, D, E, H, I, J, and K, four macrocells are
connected to I/O pins and 12 are buried. Moreover, in addition
to the I/O and buried macrocells, there are 32 single product
term logic expanders in each LAB. Their use greatly enhances
the capability of the macrocells without increasing the number
of product terms in each macrocell.

Notes:
1. Minimum DC input is –0.3V. During transactions, input may undershoot to –2.0V or overshoot to 7.0V for input currents less then 100 mA and periods shorter
than 20 ns.
2. The IOH parameter refers to high-level TTL output current; the IOL parameter refers to low-level TTL output current.
3. The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
