71V256SA12PZGI8

Overview

The Renesas Electronics Corporation 71V256SA12PZGI8 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 maximum access time of 12 ns and operates on a single 3.3V power supply with a voltage range of 3V to 3.6V. The device utilizes a 28-pin TSOP package for surface-mount installation. It supports an industrial temperature range from -40°C to +85°C and includes low standby current characteristics to extend battery life in portable applications.

Feature Summary

Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
Low standby power consumption ensuring extended battery life in portable devices
LVTTL-compatible inputs and outputs for direct interface with logic systems
Industrial temperature grade availability for robust environmental performance

Applications

High-performance processor secondary cache memory
Portable consumer electronics requiring low power consumption
Industrial equipment operating within wide temperature ranges
Embedded systems utilizing asynchronous data buffering

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm lead-free compliance and moisture sensitivity level handling requirements during assembly. Check for specific RoHS directive adherence relevant to the manufacturing date code. Ensure proper electrostatic discharge precautions are maintained throughout the supply chain and storage phases.

Selection Notes

Select this component for designs requiring fast asynchronous access without clock synchronization. Consider the 28-pin TSOP footprint for space-constrained printed circuit board layouts. Evaluate the 12 ns speed against system timing requirements. Verify that the 3.3V logic levels match the host microcontroller or processor I/O specifications.
