AS6C62256-55STIN
Overview
The AS6C62256-55STIN is a 256K-bit asynchronous CMOS static RAM organized as 32,768 words by 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 low-power 3.3V architectures. This memory device features a low standby current of 30uA, making it ideal for battery-backed non-volatile storage applications.
Why Choose This Part
The device offers fully static operation, eliminating the need for external refresh clocking and simplifying the memory controller interface. Its wide operating temperature range of -40C to +85C and industrial-grade reliability make it suitable for harsh environments. Additionally, the tri-state output and simple CE, OE, and WE control logic allow for easy bus integration.
Applications
Getting Started
To interface this SRAM, connect the 15-bit address bus and 8-bit data bus to your microcontroller's external memory interface (EMI) or GPIOs. Ensure the chip enable (CE) and output enable (OE) pins are properly sequenced according to the 55ns access time specifications. For battery-backed operation, use a voltage supervisor or a diode-OR circuit to transition the VDD pin to a secondary power source.
