71V321L55PF

Overview

The 71V321L55PF is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 16 kbit, organized as 2K x 8 bits. The device features an asynchronous parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 3 V to 3.6 V and supports surface-mount installation in a 64-TQFP package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array from two distinct ports.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller designs
• FIFO buffer applications requiring independent read/write operations

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature rating. Confirm RoHS compliance status for the exact part number variant before integration. Check for active production status or obsolescence notices via manufacturer channels. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when independent concurrent access to shared memory data is required. Compare access speeds and power consumption against single-port alternatives if only sequential access is needed. Verify that the 64-TQFP footprint matches the target PCB layout constraints. Ensure the operating voltage range aligns with the system's power supply rails.

Part Context

This component belongs to the 71V321L series of dual-port SRAMs. The '55' designation indicates the 55 ns access speed grade. The 'PF' suffix typically denotes the 64-lead Thin Quad Flat Package. This series serves as a standard solution for non-volatile-like temporary storage in synchronous and asynchronous logic circuits.

Replacement Considerations

Direct pin-compatible replacements may include other 71V321L series variants with different speed grades or packaging options. Verify electrical compatibility and timing parameters before substituting with components from other manufacturers.
