Memory IC Overview

The Renesas Electronics Corporation 71321SA55JI8 is a high-speed asynchronous dual-port static random access memory (SRAM) with a storage capacity of 16 kbit, organized as 2k x 8. It features a parallel interface and a maximum access time of 55 ns. The device operates on a single 4.5 V to 5.5 V power supply and supports surface mount installation in a 52-PLCC package. It functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous access by two masters
Asynchronous operation requiring no external clock signals
High-speed data transfer capabilities for system integration

Memory IC Applications

Data buffering in communication systems
Cache memory implementation in embedded processors
FIFO buffer applications in digital signal processing

Memory IC Procurement Notes

This component is officially listed as obsolete and has been discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Engineering teams must initiate replacement part selection immediately due to end-of-life status. Ensure final design decisions account for long-term supply constraints associated with legacy components.

Memory IC Selection Notes

Designers should evaluate the dual-port functionality against single-port alternatives if simultaneous access is not required. Verify that the 55 ns access time meets system timing requirements. Consider the PLCC-52 package dimensions for PCB layout compatibility. Assess thermal performance within the specified industrial temperature range during operation.

Memory IC Part Context

The 71321SA series belongs to Renesas' portfolio of high-speed CMOS SRAMs. This specific model represents the dual-port variant within the 16 kbit density class. It is designed for applications requiring concurrent read/write operations from separate ports without bus contention.
