DESCRIPTION
The Microchip Technology Inc. 37LV36/65/128 is a
family of Serial OTP EPROM devices organized inter-
nally in a x32 configuration. The family also features a
cascadable option for increased memory storage
where needed. The 37LV36/65/128 is suitable for
many applications in which look-up table information
storage is desirable and provides full static operation in
the 3.0V to 6.0V V
CC
range. The devices also support
the industry standard serial interface to the popular
RAM-based Field Programmable Gate Arrays (FPGA).
Advanced CMOS technology makes this an ideal boot-
strap solution for today's high speed SRAM-based
FPGAs. The 37LV36/65/128 family is available in the
standard 8-pin plastic DIP, 8-pin SOIC and 20-pin
PLCC packages.
