IDT71256SA20PZ8

Memory IC Overview

The IDT71256SA20PZ8 is a 32K x 8 asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates on a single 5V supply with a voltage range of 4.5V to 5.5V. The device features a maximum access time of 20ns and utilizes parallel interface technology. It is housed in a 28-pin TSOP package designed for surface-mount installation. The component supports commercial temperature ranges and includes low-power standby modes to reduce system energy consumption.

Memory IC Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles
• Low-power operation with reduced standby mode capabilities
• Direct TTL-compatible input and output interfaces

Memory IC Applications

• High-performance processor secondary cache systems
• Industrial control applications requiring reliable data storage
• Commercial electronic devices utilizing 5V logic levels

Memory IC Procurement Notes

Verify the exact suffix PZ8 against manufacturer documentation to confirm package type and moisture sensitivity level. Confirm end-of-life status as many variants in this series are obsolete. Ensure compatibility with existing PCB footprints for 28-pin TSOP packages before procurement.

Memory IC Selection Notes

Select this component when a 20ns access speed is required for 32Kx8 SRAM configurations. Consider the 28-pin TSOP form factor for surface-mount assembly constraints. Evaluate power requirements against the low-power standby specifications if battery backup or extended life is necessary.

Memory IC Part Context

This part belongs to the 71256 family of CMOS SRAMs, which offers various speed grades and packaging options. The SA variant typically denotes specific performance characteristics within the broader product line. These components are widely used in legacy and industrial systems requiring robust, non-volatile-like static memory solutions without complex refresh logic.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes such as IDT71256SA20PZG or other 20ns variants in the same package. Verify electrical parameters match exactly, particularly access times and supply voltage ranges, before substituting.
