D4364C-15L 8-BIT Static CMOS RAM 28-Pin DIP

Description

The uPD4364 is a high-speed, 8192-word by 8-bit static RAM. Its unique circuitry, using CMOS peripheral circuits and N-channel memory cells with polysilicon resistors, makes the uPD4364 a very low-power device that requires no clock or refreshing to operate.

Two chip enable pins are provided for battery backup application, and an output enable pin is provided for easy interface. Data retention is guaranteed at a power supply voltage as low as 2 V (-xxL and -xxLL versions).

The uPD4364 is packaged in standard 28-pin Plastic DIP
