7133LA15JI8

Overview

The 7133LA15JI8 is a 32Kbit (2K x 16) dual-port asynchronous SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with a 15 ns access time and operates on a single 5V supply voltage ranging from 4.5V to 5.5V. The device utilizes CMOS technology and is housed in a 68-pin PLCC package. Maximum power consumption is specified at 200 mA, and it supports an industrial temperature range of -40°C to +85°C.

Feature Summary

Dual-port architecture enabling independent simultaneous access for two processors
Asynchronous operation with fast 15 ns access time
Single 5V power supply compatibility

Applications

High-speed data buffering between microprocessors
Cache memory systems requiring concurrent read/write operations
Embedded control applications with strict timing requirements

Procurement Notes

This component is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement is restricted to existing stock or third-party distributors. Verify authenticity carefully due to potential surplus market availability. Confirm package integrity and moisture sensitivity levels before integration into production lines.

Selection Notes

Engineers should evaluate the 7133LA20PFG8 as a primary alternative within the same family. While the substitute offers a slightly slower 20 ns access time, it maintains compatible pinouts and electrical characteristics. Ensure that system timing margins accommodate the increased latency when migrating from this obsolete part to active inventory options.

Part Context

Part of the 7133LA series of dual-port SRAMs designed for high-performance embedded systems. This specific variant provides 32Kbit capacity in a compact PLCC form factor, suitable for space-constrained designs requiring reliable non-volatile-like retention during power cycles without battery backup.
