7164L25TPGI

Overview

The Renesas Electronics Corporation 7164L25TPGI is a static random-access memory (SRAM) integrated circuit manufactured using BICMOS technology. It provides a storage capacity of 64 kbit, organized as 8k x 8 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates on a single 5V power supply, with voltage specifications ranging from 4.5 V to 5.5 V. The component is designed for surface-mount installation in a 28-pin Thin Small Outline Package (TSOP). It supports an industrial operating temperature range from -40°C to +85°C and includes humidity sensitivity considerations.

Feature Summary

• Asynchronous SRAM architecture utilizing BICMOS technology for high-speed data retention without clock requirements
• Parallel interface supporting standard 5V logic levels for direct system integration
• Industrial-grade thermal stability ensuring reliable operation across extended temperature ranges

Applications

• High-performance processor secondary cache systems
• Embedded control applications requiring fast data buffering
• Industrial automation equipment operating in harsh environments

Procurement Notes

Verify the specific suffix 'TPGI' against official manufacturer documentation to confirm package type and lead-free status. Confirm end-of-life or discontinuation status through authorized distributors prior to design finalization. Ensure compatibility with existing PCB footprints for 28-pin TSOP packages. Check for moisture sensitivity level requirements during assembly handling.

Selection Notes

Select this component when a 64 kbit asynchronous SRAM with 25 ns access speed is required for 5V logic systems. Consider the 28-pin TSOP package for surface-mount constraints. Evaluate the industrial temperature range suitability for the target environment. Compare power consumption metrics against alternative CMOS SRAM options if low standby current is critical.
