Overview

The IS61WV5128BLL-10TLI is a high-speed, 4Mbit asynchronous CMOS static RAM organized as 512K words by 8 bits. It operates on a low-voltage supply ranging from 2.4V to 3.6V and features a very fast access time of 10 ns, making it suitable for high-performance memory buffering and cache applications.

Why Choose This Part

This SRAM offers a superior balance of speed and power consumption, featuring a 45mA operating current and a 15mA standby current. Its asynchronous design simplifies the hardware interface by eliminating the need for a system clock, while the lead-free 44-pin TSOP-II package ensures easy integration into dense PCB layouts.

Applications

High-Speed Data Buffering
Used in networking equipment and communication interfaces where 10 ns access times are required for rapid packet processing.
Embedded System Cache
Acts as external fast-access memory for microcontrollers or DSPs that lack sufficient internal RAM for intensive algorithms.
Industrial Control Systems
Provides reliable volatile storage for PLC real-time operating data across an industrial temperature range of -40C to 85C.

Getting Started

To integrate this device, interface the 19 address lines and 8 data lines directly to your processor's external memory interface (EMI) or FSMC. Ensure stable decoupling capacitors are placed near the VDD pins to manage high-speed switching transients, and verify that your controller supports asynchronous SRAM timings for Chip Select (CS) and Write Enable (WE) signals.

Also Consider

CY7C1041G30-10ZSXI IFXInfineon Technologies - Offers similar 4Mb density and 10 ns access time but in a slightly different 44-pin TSOP II package configuration.
