Overview

The IS61LV25616AL-10TL is a high-speed, 4Mbit asynchronous CMOS static RAM organized as 256K words by 16 bits. It operates on a single 3.3V power supply and features a rapid 10ns access time, making it suitable for high-performance buffered memory applications.

Why Choose This Part

This SRAM offers fully static operation, eliminating the need for complex refresh circuitry or external clocks. Its asynchronous interface with separate upper and lower byte controls provides flexible data management and eases integration with various 16-bit bus architectures.

Applications

Microprocessor Cache
Used as a high-speed external cache memory for legacy or high-performance embedded processors requiring fast data retrieval.
Communication Buffering
Acts as a temporary data buffer in networking equipment and industrial communication controllers to manage high-speed data streams.
Embedded Computing
Provides volatile working memory for embedded systems where a simple, non-multiplexed parallel interface is preferred over DRAM.
Instrumentation and Control
Serves as data storage in high-speed digital signal acquisition systems where 10ns cycle times are required.

Getting Started

To use this device, interface the 18-bit address bus and 16-bit data bus directly to your microcontroller's external memory interface (EMIF) or FSMC. Ensure the 3.3V supply is well-decoupled and that PCB trace lengths for the 10ns timing signals are kept short to minimize signal integrity issues.
