71421SA35PF

Overview

The Renesas Electronics Corporation 71421SA35PF is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-TQFP package measuring 14x14 mm. The component is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

Dual-port architecture enabling independent simultaneous access to the same memory array from two separate ports.

Applications

High-speed data buffering in communication systems
Cache memory implementation in embedded processors
Real-time data logging applications

Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement should prioritize validated replacement parts to ensure long-term supply chain stability and compliance with project lifecycle requirements.

Selection Notes

Designers requiring this specific memory configuration must account for the discontinuation of the 71421SA35PF. Selection criteria should focus on identifying compatible replacements that match the 16Kb capacity, 35ns speed, and 64-pin TQFP form factor. Verify that alternative components support the required dual-port functionality and operate within the specified voltage and temperature parameters.

Part Context

The 71421SA series belongs to Renesas Electronics' portfolio of high-performance dual-port SRAMs. These devices are engineered for applications demanding concurrent read/write operations without bus contention. The SA suffix typically denotes standard industrial temperature ranges and specific packaging options within the broader family of asynchronous memory solutions.
