Overview

The IS62WV51216BLL-55TLI is an 8Mbit (512K x 16) volatile CMOS Static RAM. It offers fully static operation, meaning no clock or refresh is required, simplifying its integration into systems. With an access time of 55 ns, it provides fast data retrieval for various embedded applications. This surface mount memory IC operates from a 2.5V to 3.6V supply.

Why Choose This Part

This SRAM offers fully static operation, eliminating the need for complex refresh cycles and simplifying memory control logic. Its wide voltage supply range of 2.5V to 3.6V provides design flexibility for various power schemes. The industrial temperature rating ensures robust performance in challenging operating environments.

Applications

Data Buffering
Ideal for temporary storage of data in embedded systems where fast read/write speeds are critical, such as in microcontrollers or DSPs requiring scratchpad memory.
Embedded System Memory
Suitable for adding external RAM to microprocessors or microcontrollers that require more volatile memory than internally available for code execution or data handling.
Industrial Control Systems
Its industrial temperature range (-40C to 85C) makes it suitable for use in rugged environments found in industrial automation and control equipment.
Medical Devices
Can be used in medical instrumentation for data logging, real-time data processing, or buffering sensor readings due to its reliable static operation.
Communication Equipment
Useful in network devices or telecommunication systems for packet buffering or temporary storage of communication protocols.

Getting Started

Integrating this parallel SRAM typically involves interfacing with a microcontroller or microprocessor's external memory bus. Engineers will need to configure the host controller's memory controller (if available) or implement GPIO-based control for address, data, and control signals (chip enable, output enable, write enable, byte enables). Consult the host controller's documentation for external memory interfacing guidelines.
