The Microchip Technology Inc. 37LV56 is a family of Serial OTP EPROM devices organized inter-nally in a x32 configuration.  The 37LV56 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 VCC 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 37LV56 family is available in the standard 8-pin plastic DIP, 8-pin SOIC and 20-pin PLCC packages.
