71421SA25PF

Overview

The Renesas Electronics Corporation 71421SA25PF is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters. The component is designed for commercial temperature ranges spanning from 0°C to 70°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports high-speed asynchronous parallel data transfer
• Utilizes CMOS technology for low power consumption

Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control equipment with real-time processing needs
• Telecommunications infrastructure hardware

Procurement Notes

Verify the specific suffix configuration against official documentation, as variations may exist. Confirm RoHS compliance status prior to integration, as older manufacturing runs may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings on distributor platforms before finalizing procurement plans. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements.

Selection Notes

Select this component when dual-port functionality is required for separate processor or controller access to shared memory. Compare access speeds and package dimensions against alternative models in the 71421 series. Evaluate power consumption characteristics relative to system battery or thermal constraints. Verify that the 5-volt logic levels match the target application's I/O specifications.

Part Context

This part belongs to the Renesas 71421 series of dual-port SRAMs, which are designed for applications requiring fast, independent access from two different masters. The series typically offers various speed grades and package options to suit different performance and form factor requirements in industrial and communication systems.

Replacement Considerations

Consult official manufacturer resources for verified cross-reference parts. Ensure any substitute maintains identical pinout, voltage levels, and timing parameters to guarantee functional compatibility without redesigning the host circuit.
