71V256SA12PZG8

Overview

The Renesas Electronics Corporation 71V256SA12PZG8 is a 3.3V CMOS asynchronous static random-access memory (SRAM) organized as 32K x 8, providing a total storage capacity of 256 kbit. It features a parallel interface with a maximum access time of 12 ns and operates within a supply voltage range of 3 V to 3.6 V. The device utilizes a 28-pin TSOP package designed for surface-mount technology applications.

Feature Summary

• Fully static asynchronous circuitry eliminates the need for external clocks or periodic refresh cycles during operation.
• Low standby power consumption ensures extended battery life when the chip select input is at a CMOS level.
• LVTTL-compatible inputs and outputs allow direct interfacing with standard logic families.

Applications

• High-performance processor secondary cache systems
• Industrial equipment requiring reliable data retention
• Consumer electronics utilizing single-supply architectures

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence status. Confirm moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing PCB footprints and verify that the specific suffix denotes the correct reel packaging configuration for automated placement processes.

Selection Notes

Select this component for designs requiring fast asynchronous access without clock synchronization overhead. Consider the 12 ns speed grade for moderate performance needs. Evaluate the 28-pin TSOP form factor against available board space constraints and thermal dissipation capabilities inherent to the surface-mount implementation.

Part Context

This part belongs to the 71V256SA series of 3.3V SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other variants in the family but is distinguished by its specific 12 ns access time and TSOP-28 physical package configuration intended for compact electronic assemblies.

Replacement Considerations
