Overview

The AS6C1016-55BIN is a 1Mbit low-power CMOS static random access memory (SRAM) organized as 64K words by 16 bits. It operates over a wide voltage range of 2.7V to 5.5V, making it compatible with both 3.3V and 5V logic systems while maintaining a very low standby current of 2uA.

Why Choose This Part

This SRAM offers fully static operation, meaning no external clock or refreshing is required, which simplifies the timing interface for the designer. Its broad supply range of 2.7V to 5.5V and industrial temperature rating of -40C to 85C ensure reliability across diverse power environments and harsh conditions.

Applications

Industrial Controller Buffer
Used as volatile workspace for PLCs or motor controllers requiring fast 55ns access times without refresh cycles.
Battery-Backed Data Logging
The low 2uA standby current allows for long-term data retention when paired with a small lithium coin cell.
Legacy System Maintenance
Ideal for replacing obsolete asynchronous SRAM in 16-bit embedded systems or providing additional RAM for older microprocessors.

Getting Started

To interface this SRAM, connect the 16-bit data bus and 16-bit address bus to your microcontroller's external memory interface (EMC/FSMC). Ensure byte control pins (LB, UB) are correctly asserted for 8-bit or 16-bit operations, and utilize the tri-state outputs to manage bus contention.
