Overview

The AS6C1008-55TIN is a 1Mbit low-power CMOS static RAM organized as 128K x 8 bits. It operates from a wide voltage range of 2.7V to 5.5V, making it compatible with both legacy 5V systems and modern low-power 3.3V microcontrollers. With a fast access time of 55ns and an ultra-low standby current of 1uA typical, it is ideal for battery-backed non-volatile memory applications.

Why Choose This Part

This SRAM offers high reliability with a simple asynchronous interface that requires no clock signals, simplifying the timing design for hardware engineers. Its wide supply voltage range from 2.7V to 5.5V provides significant design flexibility across different logic families. Furthermore, the 32-pin TSOP-I package helps save PCB real estate compared to traditional DIP or larger SOP footprints.

Applications

Battery-Backed Data Logging
Utilizes the ultra-low standby current to preserve critical system data using a small lithium coin cell during power-off states.
Industrial Embedded Systems
Provides reliable workspace memory for 8-bit and 16-bit microcontrollers in environments requiring an industrial temperature range of -40C to +85C.
Communication Buffers
Acts as a high-speed temporary buffer for data packets in networking or serial communication hardware using its 55ns access time.
Legacy System Maintenance
Serves as a drop-in replacement for older 128KB SRAMs in 5V legacy industrial control boards.

Getting Started

To use this device, interface the 17 address lines and 8 data lines directly to your microcontroller's external memory interface (EMIF) or bit-bang using GPIO for slower applications. Ensure proper decoupling with a 0.1uF ceramic capacitor placed close to the VDD pin (Pin 32). For battery-backed operation, use a voltage supervisor or a simple diode-OR circuit to switch between main power and a backup battery.
