Memory IC datasheet and documents for 71321SA55J8

71321SA55J8

Memory IC Overview

The 71321SA55J8 is a high-speed 16 kbit (2K x 8) dual-port static random access memory manufactured by Renesas Electronics. It features asynchronous parallel interface with 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-pin PLCC package. It includes internal interrupt logic for interprocessor communication and automatic power-down capabilities.

Memory IC Feature Summary

True dual-ported memory cells enabling simultaneous independent access to the same memory location from both ports.
Integrated interrupt flags facilitating direct port-to-port communications without external discrete logic.
On-chip arbitration logic with BUSY output flag to manage concurrent access conflicts automatically.

Memory IC Applications

Interprocessor communication in multi-core systems
Stand-alone 8-bit dual-port RAM applications
Master dual-port RAM configuration in 16-bit or wider data bus systems

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications and regulatory requirements.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required between two processors. Ensure system voltage aligns with the specified 4.5 V to 5.5 V range. Consider the 52-pin PLCC footprint for PCB layout constraints and verify thermal management needs for the commercial temperature range operation.

Memory IC Part Context

This device belongs to the 71321 series of dual-port SRAMs, designed for high-speed data buffering and sharing. It serves as a master unit that can expand data bus width when paired with slave devices like the 71421. The architecture eliminates the need for additional control logic in standard 8-bit configurations.
