71V256SA12YG

Overview

The 71V256SA12YG is a 3.3V CMOS asynchronous static random access memory manufactured by Renesas Electronics Corporation. It features a storage capacity of 256 kbit organized as 32K x 8. The device offers a maximum access time of 12 ns and operates within a voltage range of 3 V to 3.6 V. Maximum power supply current is specified at 90 mA. It supports parallel interface communication and utilizes a 28-pin SOJ surface-mount package. The component is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
• Low standby power consumption contributing to extended battery life in portable applications
• LVTTL-compatible inputs and outputs for direct interfacing with logic systems

Applications

• High-performance processor secondary cache
• Battery-powered equipment requiring low standby current
• General-purpose memory storage in embedded systems

Procurement Notes

Verify the specific suffix YG confirms the 28-pin SOJ package and commercial temperature grade. Confirm RoHS compliance status through official documentation, as manufacturing changes may affect regulatory adherence. Check for obsolescence notices or product change notifications from Renesas Electronics prior to finalizing procurement plans.

Selection Notes

Select this component when a 32K x 8 organization with 12 ns access speed is required. Ensure the design accommodates the 3.3V single supply voltage and LVTTL logic levels. Verify that the SOJ-28 footprint matches the PCB layout constraints and that the commercial temperature range meets the operational environment requirements.
