71V256SA10PZG

Overview

The IDT 71V256SA10PZG is a 3.3V asynchronous static random-access memory (SRAM) device manufactured by Integrated Device Technology. It provides a total storage capacity of 256K bits, organized as 32K words by 8 bits. The component features a parallel interface with a maximum access time of 10 ns. It operates within a supply voltage range of 3.0 V to 3.6 V and supports surface-mount installation in a 28-pin TSOP package.

Feature Summary

• Asynchronous operation for flexible system integration
• Single 3.3V power supply requirement
• Parallel data interface architecture

Applications

• General-purpose data buffering
• Cache memory systems
• Embedded control applications

Procurement Notes

Verify the manufacturer origin, as Renesas Electronics also produces equivalent parts under this numbering scheme. Confirm the specific suffix indicates the correct package type and lead finish. Ensure compliance with RoHS directives if required by the target assembly process. Check for product discontinuance notices from the original manufacturer or current rights holder.

Selection Notes

Select this component when a low-power, high-speed asynchronous SRAM is required for small data storage needs. The 10 ns access time suits moderate-speed digital logic. Compare pin compatibility with existing designs. Consider the 28-TSOP footprint constraints during PCB layout. Evaluate thermal dissipation requirements based on the operating current specifications.

Part Context

This part belongs to the 71V256SA series of 3.3V asynchronous SRAMs. The family offers various access times to balance performance and power consumption. Integration into systems typically involves direct connection to microprocessors or FPGAs via standard parallel buses. The technology represents a mature solution for non-volatile-less temporary data retention.

Replacement Considerations

IDT71V256SA10PZG serves as an alternative designation for the same component. Verify pinout compatibility before substitution.
