AS7C256B-15JIN

Overview

The AS7C256B-15JIN is a 256Kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates within a voltage range of 4.5V to 5.5V with a maximum access time of 15ns and a maximum supply current of 70mA. The component is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

Asynchronous parallel interface architecture
Industrial-grade wide temperature operation
Surface-mount SOJ packaging

Applications

Industrial control systems
Embedded data storage
Consumer electronics

Procurement Notes

Verify the specific suffix 'JIN' against official datasheets to confirm the 28-pin SOJ package and industrial temperature rating. Ensure compatibility with 4.5V to 5.5V power supplies. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component for designs requiring 256Kbit capacity with 15ns speed in harsh environments. The SOJ package suits surface-mount assembly processes. Verify that the 70mA current draw fits the system power budget and that the 4.5V minimum voltage aligns with the logic level requirements.

Part Context

This part belongs to the AS7C256B series of fast asynchronous SRAMs. It offers non-volatile-like retention characteristics without the complexity of flash memory. The industrial temperature variant ensures reliability in demanding operational conditions compared to commercial grade alternatives.
