Memory IC Overview

The 71321LA35PFI8 is a high-speed 2K x 8 dual-port static RAM featuring internal interrupt logic for interprocessor communications. It operates within a voltage range of 4.5V to 5.5V and supports an access time of 35 ns. The device is housed in a 64-pin TQFP package with dimensions of 14.0 x 14.0 mm and a height of 1.4 mm. It includes an automatic power-down feature controlled by the chip enable signal, allowing low standby power consumption.

Memory IC Feature Summary

Dual-port architecture enabling simultaneous independent access by two processors
Integrated interrupt logic facilitating direct interprocessor communication without discrete logic
Automatic power-down mode activated by chip enable control for reduced standby power

Memory IC Applications

Stand-alone 8-bit dual-port memory systems
Master dual-port RAM configuration in 16-bit or wider word width systems paired with slave devices
Interprocessor communication interfaces requiring full-speed error-free operation

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm RoHS compliance status as historical data indicates variations across production batches. Check moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate package type against specific PCB footprint designs before procurement.

Memory IC Selection Notes

Select this component for applications requiring asynchronous dual-port SRAM with integrated communication logic. Ensure supply voltage matches the 4.5V to 5.5V operating range. Consider the 35 ns access speed relative to system timing requirements. Verify thermal performance within the specified commercial temperature range.

Memory IC Part Context

This part belongs to the 71321 series of dual-port SRAMs manufactured by Renesas Electronics. It is designed to function independently or as a master unit in expanded memory configurations. The series emphasizes high-speed data transfer and simplified system design by eliminating external arbitration logic for port control.
