IDT71V124SA10YI

Memory IC Overview

The IDT71V124SA10YI is a 1 Megabit (128K x 8) high-speed CMOS static RAM. It operates on a single 3.3V supply with an address access time of 10ns and a read cycle time of 10ns. The device features LVTTL-compatible inputs and outputs, utilizing one Chip Select and one Output Enable pin for control. It employs a JEDEC center power/GND pinout to reduce noise. The component supports commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Utilizes a JEDEC center power and ground pinout configuration to minimize system noise generation.
• Features fully static asynchronous circuitry that requires no clocks or refresh cycles for operation.
• Incorporates low power consumption capabilities through chip deselect standby modes.

Memory IC Applications

• High-speed memory buffering in industrial systems
• Data storage in consumer electronics requiring fast access times
• Embedded applications needing reliable static RAM without clock synchronization

Memory IC Procurement Notes

Verify the specific suffix 'YI' corresponds to the 300-mil SOJ package and Industrial temperature range as defined in official Renesas ordering guides. Confirm RoHS compliance status and lead-free designation prior to procurement. Ensure compatibility with existing board layouts regarding the 32-pin plastic SOJ footprint and center power/ground pin arrangement.

Memory IC Selection Notes

Select this component when a 10ns access speed is required within a 3.3V logic environment. The Industrial temperature rating (-40°C to +85°C) makes it suitable for harsher operating conditions compared to commercial grades. The center power/ground pinout is advantageous for designs prioritizing signal integrity and reduced electromagnetic interference.

Memory IC Part Context

This part belongs to the IDT71V124 family of 1 Megabit SRAMs. The 'SA' indicates the 3.3V variant, while '10' specifies the 10ns speed grade. The 'Y' denotes the 300-mil SOJ package type, and 'I' signifies the Industrial temperature range. Integrated Device Technology was acquired by Renesas Electronics Corporation.

Memory IC Replacement Considerations

Compatible substitutes include other 128K x 8 asynchronous SRAMs with 10ns access times and 3.3V operation. Verify pinout compatibility, specifically the center power/ground arrangement, to ensure direct replacement without PCB redesign.
