SRAM 128Kx8 ASYNCHRONOUS 5.0V STATIC RAM
6,349 in stock

Overview

The 71024S15TYGI is a high-speed 1Mbit asynchronous CMOS static RAM organized as 128K x 8 bits. It operates on a 5V power supply and features a rapid 15ns access time, making it suitable for high-performance legacy systems and industrial controllers requiring fast memory access without complex timing requirements.

Why Choose This Part

This SRAM offers fully static operation, requiring no clocks or refreshing, which simplifies the interface logic for the designer. Its 15ns access time and TTL-compatible I/O facilitate easy integration with high-speed 5V microcontrollers and digital signal processors.

Applications

Industrial Control Systems
Used as fast cache or buffer memory in PLC units and industrial automation controllers that utilize 5V logic.
Legacy System Maintenance
Serves as a drop-in replacement for older 128K x 8 asynchronous SRAMs in vintage computing or legacy embedded hardware.
High-Speed Data Buffering
Provides volatile storage for data streams in communications equipment where a simple parallel interface is preferred over SPI or DDR.

Getting Started

To use this part, connect the 17-bit address bus and 8-bit data bus to your processor; ensure the Chip Select (CS), Output Enable (OE), and Write Enable (WE) pins are managed according to the 15ns timing requirements. Use 0.1uF ceramic decoupling capacitors close to the VDD pin to minimize noise during high-speed switching.
