71321LA17PFI

Memory IC Overview

The Renesas Electronics Corporation 71321LA17PFI is a high-speed 2K x 8 dual-port static RAM featuring internal interrupt logic for interprocessor communications. It operates with a maximum access time of 17 ns and supports a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 64-pin TQFP package with dimensions of 14.0 mm x 14.0 mm and a height of 1.4 mm. Designed for standalone 8-bit applications or as a master unit paired with the 71421 slave, it enables full-speed operation without additional discrete logic.

Memory IC Feature Summary

Dual-port architecture with integrated interrupt logic for direct interprocessor communication
Automatic power-down mode controlled by chip enable signals for low standby power
Master configuration capability for expanding word width when used with compatible slave devices

Memory IC Applications

Interprocessor communication in multi-processor systems
Standalone 8-bit dual-port memory applications
Master memory units in 16-bit or wider parallel data bus systems

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure packaging specifications match design requirements. Review datasheet revisions for any parameter updates. Validate lead-free status if required by environmental regulations.

Memory IC Selection Notes

Select this component for designs requiring fast asynchronous dual-port access with built-in signaling. Compare access times against system timing constraints. Evaluate thermal performance within the specified operating temperature range. Consider pin compatibility with existing PCB layouts. Assess power consumption profiles during active and standby modes.

Memory IC Part Context

This part belongs to the IDT/Renesas 71321/71421 family of dual-port SRAMs. The 'LA' suffix typically denotes commercial temperature range and specific speed grades.
