Memory IC Overview

The Renesas 71421SA25J is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 16 kbit, organized as 2K x 8 bits. It features an asynchronous parallel interface with a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-TQFP package. It is designed for industrial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous access by two processors
Asynchronous operation without clock synchronization requirements
Parallel data interface for direct system bus connectivity

Memory IC Applications

High-speed data buffering between microprocessors
Cache memory implementation in embedded systems
Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this variant may not meet current environmental standards. Validate package pinout compatibility during design-in phase to ensure correct footprint alignment.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure the 5V logic level matches system voltage rails. Consider the 64-TQFP package constraints for PCB layout density. Evaluate thermal dissipation needs within the specified operating temperature range.

Memory IC Part Context

This part belongs to the Renesas 71421SA/LA series of dual-port SRAMs. It shares architectural similarities with other members like the 71321SA and 71421LA variants, differing primarily in speed grades and package options. The series provides non-volatile-like persistence for volatile memory applications requiring high-speed bidirectional data transfer.
