71V256SA12YGI8

Overview

The 71V256SA12YGI8 is a 3.3V CMOS asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit, organized as 256 k x 16 bits. The device offers a maximum access time of 12 ns and operates within a supply voltage range of 3 V to 3.6 V. Maximum power consumption is rated at 180 mA. It supports an extended industrial temperature range from -40°C to +85°C and is housed in a 44-pin SOJ package.

Feature Summary

Asynchronous parallel interface for direct data transfer without clock synchronization
CMOS technology enabling low standby current for extended battery life
LVTTL-compatible inputs and outputs for logic level interfacing
Fully static circuitry requiring no clocks or refresh cycles

Applications

High-performance processor secondary cache systems
Industrial control applications requiring wide temperature tolerance
Embedded systems utilizing 3.3V logic families
Data buffering in communication equipment

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package integrity against moisture sensitivity level specifications prior to assembly. Ensure design-in compatibility with existing PCB footprints for the 44-pin SOJ configuration.

Selection Notes

Select this component when a 16-bit wide asynchronous SRAM is required for industrial environments. The 12 ns access speed suits moderate-frequency data processing tasks. Verify that the 44-pin SOJ form factor fits the target mechanical constraints. Consider the 3.3V operating voltage aligns with the system's power distribution network.

Part Context

This part belongs to the 71V256SA series of 3.3V asynchronous SRAMs. The series provides various access speeds and packaging options including TSOP and SOJ variants. The 71V256SA12YGI8 specifically denotes the 12 ns speed grade and industrial temperature rating within the 256k x 16 organization family.
