Memory IC datasheet and documents for 71321LA25PFI

71321LA25PFI

Memory IC Overview

The 71321LA25PFI is a high-speed, 16K-bit (2K x 8) dual-port static RAM manufactured by Renesas Electronics Corporation. It features asynchronous parallel interface operation with a maximum access time of 25 ns. The device operates on a single 5V ±10% power supply and supports industrial temperature ranges from -40°C to +85°C. It is housed in a 64-pin TQFP surface-mount package.

Memory IC Feature Summary

True dual-ported memory cells enabling simultaneous independent access to the same memory location from both ports.
Integrated internal interrupt logic providing two INT flags for efficient port-to-port processor communications.
On-chip port arbitration logic with BUSY output flag to manage concurrent access without external discrete logic.
Automatic power-down feature controlled by chip enable signals to achieve very low standby power consumption.

Memory IC Applications

Stand-alone 8-bit dual-port RAM systems
Master dual-port RAM modules in 16-bit or wider data bus configurations
Interprocessor communication interfaces requiring full-speed error-free operation

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check datasheet revisions for any pinout or electrical parameter updates before finalizing design integration.

Memory IC Selection Notes

Select this component when simultaneous bidirectional memory access is required without external arbitration hardware. Ensure system voltage aligns with the specified 5V ±10% range. Consider the 25 ns access speed against system clock requirements and verify thermal management for the industrial temperature grade.

Memory IC Part Context

This part belongs to the 71321 series of dual-port SRAMs, designed for high-performance embedded applications. It complements the 71421 slave device to expand data bus widths. The LA suffix indicates industrial temperature rating and battery backup capability down to 2V data retention.
