71V124SA12TYGI

Overview

The IDT71V124SA12TYGI is a 1Mbit (128K x 8) asynchronous static random-access memory manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply with a voltage range of 3V to 3.6V and features a 12ns access time. The device utilizes a parallel interface and is housed in a 32-BSOJ package, specifically identified as a 32-SOJ form factor. It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous SRAM architecture requiring no clock or refresh cycles for operation
• JEDEC center power and ground pinout configuration to reduce noise generation
• LVTTL-compatible bidirectional inputs and outputs for system integration

Applications

• Industrial equipment control systems
• Automotive electronic modules
• Telecommunications infrastructure hardware

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence. Confirm RoHS compliance status as specifications vary by manufacturing date. Validate package dimensions against design requirements before finalizing procurement orders.

Selection Notes

Select this component for designs requiring fast asynchronous data access without complex timing constraints. Ensure the PCB layout accommodates the specific 32-SOJ footprint and thermal characteristics for the intended operating environment.

Part Context
