CY7C346  
128-Macrocell MAX® EPLD  
The 128 macrocells in the CY7C346 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.  
Features  
• 128 macrocells in eight logic array blocks (LABs)  
• 20 dedicated inputs, up to 64 bidirectional I/O pins  
• Programmable interconnect array  
Each LAB is interconnected through the programmable inter-  
connect array, allowing all signals to be routed throughout the  
chip.  
• 0.8-micron double-metal CMOS EPROM technology  
• Available in 84-pin CLCC, PLCC, and 100-pin PGA,  
PQFP  
The speed and density of the CY7C346 allow 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 CY7C346 allows the replacement of over  
50 TTL devices. By replacing large amounts of logic, the  
CY7C346 reduces board space, part count, and increases  
system reliability.  
Functional Description  
The CY7C346 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 device to accommodate  
a variety of independent logic functions.
