AS7C1024C-12JINTR

Overview

The AS7C1024C-12JINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 160 mA. The device features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation with fast 12 ns access time
• Single-port parallel memory interface
• Industrial-grade wide temperature capability

Applications

• Industrial control systems requiring non-volatile-like data retention during power cycles
• Embedded applications needing fast local data buffering
• Consumer electronics utilizing standard 5V logic levels

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging if required for automated assembly. Confirm RoHS compliance status through official datasheets. Check current lifecycle status as this series may be subject to discontinuation notices. Ensure the SOJ-32 footprint matches the target PCB design constraints.

Selection Notes

Select this part when a 5V supply is available and single-port SRAM is sufficient. Compare against AS7C1024B variants for potential cost or availability differences. Consider AS7C31024C if a 3.3V supply rail is mandatory instead of 5V. Verify humidity sensitivity handling requirements during storage and reflow.

Part Context

This component belongs to the AS7C1024C family of high-speed SRAMs. It shares architectural similarities with the AS7C1024B but offers updated manufacturing processes. The SOJ-32 package distinguishes it from TSOP or BGA alternatives in the same capacity class.

Replacement Considerations

AS7C1024C-12JIN is the tube-packaged equivalent. AS7C1024B-12JIN is a previous generation variant with similar electrical characteristics.
