IDT71024S20Y

Memory IC Overview

The IDT71024S20Y is a 1Mb (128K x 8) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 5.0V supply and features TTL-compatible bidirectional inputs and outputs. The device utilizes fully static circuitry, eliminating the need for clocks or refresh cycles. Key electrical parameters include access times of 15ns and 20ns, with equal access and cycle times. It supports commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. The component is available in 300 and 400 mil plastic SOJ packages.

Memory IC Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package dimensions and lead finish. Ensure compatibility with existing board layouts regarding the 32-SOJ footprint. Confirm that the selected access time variant meets system timing requirements. Check for RoHS compliance status if required by project specifications. Validate supplier documentation for authenticity before procurement.

Memory IC Selection Notes

Select this component when a non-volatile-like static RAM solution is needed without refresh overhead. Consider the 128K x 8 organization for moderate data buffering needs. Evaluate the 5V operating voltage against other system rails. Assess thermal performance within the specified commercial or industrial temperature range. Compare physical package constraints with available PCB space.

Memory IC Part Context

This part belongs to the 71024 series of asynchronous SRAMs from Renesas. The series offers various access speeds and packaging options. It is designed for applications requiring fast, random access memory with simple interface protocols. The technology leverages CMOS processes for efficiency.

Memory IC Replacement Considerations

Check for direct cross-reference parts with identical pinouts and electrical characteristics. Verify that any substitute maintains the same 128K x 8 density and 5V operation. Ensure compatible package types such as SOJ are available. Confirm equivalent access times to avoid system timing violations.
