Memory IC Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature rating, as variations exist within the 7164L family. Confirm end-of-life status and last-time-buy dates via authorized distributors, as this component may be discontinued or subject to product change notices. Ensure compatibility with existing board layouts regarding pinout and mounting style before procurement.

Memory IC Selection Notes

Select this component when a through-hole asynchronous SRAM with 64Kbit capacity is required. Compare access times and voltage ranges against other 7164L variants to ensure fit for the specific application timing and power constraints. Verify that the parallel interface matches the host controller's memory bus requirements.

Memory IC Part Context

The 7164L series consists of high-speed CMOS static RAMs manufactured by Renesas Electronics. These devices are organized as 8K x 8 bits and offer fast access times suitable for various computing and industrial applications.
