71V321L25PFI8

Overview

The Renesas Electronics Corporation 71V321L25PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface with a maximum access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. It supports surface mount installation and functions across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports.

Applications

• Asynchronous data buffering in communication systems
• Cache memory implementation in embedded processors
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix 'I8' against current manufacturer documentation to confirm compliance status and package marking details. Confirm that the RoHS non-compliant status aligns with project requirements. Check for official obsolescence notices or product change notifications affecting this specific part number before finalizing procurement plans.

Selection Notes

Select this component when a 16Kb dual-port SRAM with 25ns speed is required in a 64-TQFP package. Ensure the design accommodates the 3V to 3.6V operating voltage range. Verify that the asynchronous parallel interface matches the target system bus requirements. Consider the industrial temperature range suitability for the intended environment.

Part Context

This part belongs to the Renesas 71V321L series of dual-port SRAMs. It shares the same core memory array and electrical specifications as the 71V321L25PFGI8, differing primarily in packaging type and compliance markings. The 'L' designation typically indicates low power consumption characteristics within the family.

Replacement Considerations

The 71V321L25PFGI8 is listed as a direct replacement. Verify pinout compatibility and ensure the alternative package meets mechanical constraints.
