71V321L35TF

Overview

The Renesas Electronics Corporation 71V321L35TF is a dual-port static random access memory (SRAM) IC with a storage capacity of 16Kb, organized as 2K x 8. It features asynchronous parallel interface technology and supports a supply voltage range of 3V to 3.6V. The device offers an access time and write cycle time of 35 ns. It is housed in a 64-TQFP surface-mount package measuring 10x10 mm. The component operates within a temperature range of 0°C to 70°C and is classified as non-RoHS compliant.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations for both ports
• Asynchronous operation eliminating the need for external clock signals
• Parallel data interface supporting standard logic levels

Applications

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications requiring independent port access

Procurement Notes

Verify RoHS compliance status prior to integration, as this specific part number is documented as non-compliant. Confirm end-of-life status and availability of qualified replacement components such as the 71V321L25TFG series. Ensure design-in reviews account for the specified 64-TQFP footprint and thermal requirements during assembly processes.

Selection Notes

Select this component when dual independent access is required for 16Kb memory space. Compare against the 71V321L25 series for faster performance options if system timing permits. Verify that the 3V to 3.6V operating voltage aligns with the target system power rails. Consider the commercial temperature range limitations for environmental suitability.

Part Context

This device belongs to the 71V321L family of dual-port SRAMs manufactured by Renesas Electronics. The family provides scalable memory solutions with varying speed grades and packaging options. The 71V321L35TF specifically represents the 35 ns speed grade variant within the TQFP package lineup, designed for general-purpose parallel memory applications.

Replacement Considerations

The 71V321L25TFG is listed as an upgrade substitute by the manufacturer. Verify pin compatibility and electrical parameter differences before substitution.
