Overview

The AS6C1008-55PCN is a 1Mbit low-power CMOS static RAM organized as 128K x 8 bits. It operates over a wide voltage range of 2.7V to 5.5V, making it compatible with both legacy 5V systems and modern 3.3V logic. The 32-pin PDIP package is ideal for through-hole prototyping and maintenance of vintage computing hardware.

Why Choose This Part

The part features a very low standby current of 1uA and a typical operating current of 10mA, ensuring minimal thermal impact. Its tri-state outputs and fully static operation simplify timing requirements since no external clock or refreshing is needed.

Applications

Legacy System Maintenance
Replacing failed SRAM in 8-bit and 16-bit industrial controllers or vintage computers that require 5V logic.
Microcontroller Buffer Expansion
Providing external data workspace for MCUs with parallel memory interfaces that lack sufficient internal RAM.
Battery-Backed Data Logging
Utilizing the 1.5V minimum data retention voltage and 1uA standby current for low-power non-volatile storage with a backup cell.
Educational Prototyping
Teaching computer architecture and memory bus timing on breadboards due to the easy-to-handle 0.1 inch pitch PDIP package.

Getting Started

To use this SRAM, connect the address lines (A0-A16) and data lines (I/O0-I/O7) to your controller, ensuring the Write Enable (WE#), Chip Enable (CE#), and Output Enable (OE#) pins are managed according to the 55ns access time specifications. For breadboarding, use standard 0.1 inch pitch sockets and place a 0.1uF decoupling capacitor close to the VCC pin.
