71V124SA12PHGI8

Overview

The 71V124SA12PHGI8 is a 1Mb (128K x 8) asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It operates on a single 3.0V to 3.6V power supply and features a 12 ns access time. The device utilizes a 32-pin TSOP II surface-mount package with a JEDEC center power/ground pinout configuration to minimize noise generation.

Feature Summary

• Asynchronous parallel interface architecture requiring no clock or refresh cycles
• LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
• JEDEC center power and ground pinout design to reduce system noise

Applications

• General-purpose data buffering in embedded systems
• Cache memory implementation in microcontroller-based designs
• Data storage in industrial control applications

Procurement Notes

Verify the specific suffix PHGI8 against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for product discontinuation notices as this component family may have end-of-life variants.

Selection Notes

Select this component for designs requiring fast, non-volatile-free data retention with low standby current. Ensure the PCB layout accommodates the 32-TSOP II footprint. Verify that the system voltage remains within the 3.0V to 3.6V operating window to guarantee reliable 12 ns performance.

Part Context

This part belongs to the 71V124 series of 3.3V CMOS SRAMs. It shares architectural similarities with other devices in the family but differs in access speed and packaging. The PHGI8 suffix specifically denotes the TSOP II package variant suitable for surface-mount assembly.

Replacement Considerations

Official substitutes include parts from the same 71V124 family with compatible pinouts. Verify electrical specifications such as access time and voltage range before substitution.
