71V321S35PF8

Overview

The Renesas Electronics Corporation 71V321S35PF8 is a dual-port static random-access memory (SRAM) device organized as 2K x 8 bits, providing a total storage capacity of 16 kilobits. It operates on a parallel interface with an access time of 35 nanoseconds and a write cycle time of 35 nanoseconds. The component supports a supply voltage range from 3 volts to 3.6 volts and functions within a commercial temperature range of 0°C to +70°C. It is housed in a surface-mount 64-TQFP package measuring 14x14 millimeters.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations for both ports
• Asynchronous operation without requiring external clock signals
• Parallel data interface supporting standard logic levels

Applications

• Buffering data between asynchronous system components
• Cache memory implementation in embedded systems
• Data storage in telecommunications equipment

Procurement Notes

Verify the obsolete status and end-of-life designation before procurement planning. Confirm that the RoHS compliance status meets current regulatory requirements, as indicated by non-compliance markers. Ensure design-in decisions account for the lack of future production availability and validate replacement strategies using official upgrade part numbers.

Selection Notes

Select this component only if the specific 35-nanosecond access speed and 64-pin TQFP footprint align with the target hardware constraints. Evaluate the dual-port capability against single-port alternatives if simultaneous access is not required. Verify that the 3-volt to 3.6-volt operating range matches the system power supply specifications.

Part Context

This device belongs to the 71V321L/S series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The 'S' suffix typically denotes the commercial temperature grade variant within this product family. These components are designed for applications requiring fast, independent data access through separate port interfaces.

Replacement Considerations

The official upgrade substitute is the 71V321L25PFG8. This replacement offers improved performance characteristics and updated manufacturing compliance while maintaining functional compatibility.
