71V321S35TF8

Overview

The 71V321S35TF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 16 kilobits, organized as 2048 words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and is housed in a 64-lead Thin Quad Flat Package measuring 10x10 millimeters. The component supports surface-mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two distinct processor ports.

Applications

• High-speed data buffering in embedded systems requiring concurrent access.

Procurement Notes

Verify the specific suffix TF8 against official datasheets to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status, as documentation indicates non-compliance for this variant. Check current lifecycle status, as the product may be obsolete or subject to production discontinuation notices. Ensure design-in approval accounts for moisture sensitivity level requirements during soldering processes.

Selection Notes

Select this component when a system requires independent dual-port memory access for asynchronous data handling. Verify that the 35 ns access speed meets timing constraints for both ports. Ensure the PCB layout accommodates the 64-TQFP footprint and that power supply decoupling supports the 3V to 3.6V operating range. Consider thermal management within the commercial temperature grade limits.

Part Context

This part belongs to the 71V321S family of dual-port SRAMs from Renesas. It shares architectural similarities with other variants in the series but differs in package type and speed grade. The 'S' designation typically denotes specific speed and package characteristics within the product line. It serves as a volatile memory solution for applications needing high-bandwidth data exchange between processors.

Replacement Considerations

Consult official Renesas Product Change Notices for authorized substitutes. Verify pin-to-pin compatibility and electrical parameter equivalence before replacement.
