AS7C1024B-12JINTR

Overview

The AS7C1024B-12JINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V with a maximum supply current of 100 mA. The device features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface-mount technology. The component supports single data rate (SDR) operation and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel interface for standard memory control
• High-speed 12 ns access time for rapid data retrieval
• Industrial-grade thermal stability for harsh environments

Applications

• Industrial automation control systems
• Embedded storage in consumer electronics
• Telecommunications equipment memory buffers

Procurement Notes

Verify the specific suffix JINTR against official datasheets to confirm tape-and-reel packaging and industrial temperature ratings. Ensure compatibility with 5V logic levels and check for moisture sensitivity handling requirements during assembly. Confirm end-of-life status or discontinuation notices prior to final design approval.

Selection Notes

Select this part when a 128K x 8 organization is required with 5V operation. Compare against AS7C1024B-12JIN for tube packaging alternatives. Consider AS7C31024B variants if 3.3V operation is necessary instead of 5V. Verify pinout compatibility with existing PCB layouts before integration.

Part Context

This component belongs to the AS7C1024B series of high-speed SRAMs. It shares architectural similarities with other members like AS7C1024B-12JIN but differs in packaging format and temperature grade. The series is designed for applications requiring fast, non-volatile-like retention without the complexity of flash programming.

Replacement Considerations

AS7C1024B-12JIN offers identical electrical specifications but uses tube packaging instead of tape-and-reel.
