71V321L25PFG8

Overview

The Renesas Electronics Corporation 71V321L25PFG8 is a static random-access memory component organized as 2K x 8, providing a total storage capacity of 16 kbit. It operates with an asynchronous parallel interface and features a maximum access time of 25 ns. The device supports a supply voltage range from 3 V to 3.6 V, with a maximum power supply current of 100 mA. It is designed for surface-mount installation in a TQFP-64 package. The operational temperature range spans from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation requiring no external clock signals
• Single 3.3V power supply compatibility

Applications

• High-performance processor secondary cache systems
• Data buffering in communication equipment
• Industrial control system memory modules

Procurement Notes

Verify the specific suffix PFG8 against official datasheets to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure design-in requirements match the specified 3V to 3.6V operating voltage range and commercial temperature limits.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling without arbitration delays. Compare against single-port alternatives if only one master accesses the memory. Verify that the 25 ns access speed meets system timing constraints and that the TQFP-64 footprint fits the PCB layout.

Part Context

This part belongs to the 71V321L25 series of asynchronous SRAMs. It serves as a direct upgrade replacement for obsolete variants such as the 71V321S25PF8 and 71V321L35PF8. The series provides reliable volatile memory solutions for embedded applications requiring fast read/write cycles.

Replacement Considerations

The 71V321L25PFG8 is documented as an upgrade substitute for the discontinued 71V321S25PF8 and 71V321L35PF8 models.
