AS7C31025B-10JCN

Overview

The AS7C31025B-10JCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package designed for surface-mount technology. It supports single data rate operations and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 70 mA.

Feature Summary

• Asynchronous operation with fast 10 ns access times
• Single voltage supply compatibility at 3.3 V nominal
• Surface-mount 32-pin SOJ packaging for compact integration

Applications

• Embedded systems requiring non-volatile-like speed without retention
• Industrial control units operating in commercial environments
• Consumer electronics utilizing 3.3 V logic families

Procurement Notes

Verify the specific suffix JCN confirms the 32-pin SOJ package and commercial temperature grade against official datasheets. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure design-in reviews account for the moisture sensitivity level indicated in the component specifications to prevent handling damage during assembly processes.

Selection Notes

Select this component when a 128K x 8 organization is required with 10 ns performance under 3.3 V conditions. Compare against the AS7C31024B series for pin-compatible alternatives if different access speeds or industrial temperature ranges are needed. Validate that the SOJ footprint matches the target PCB layout constraints and soldering profiles.

Part Context

This part belongs to the AS7C31025B family of high-speed SRAMs. It shares architectural similarities with other members like the AS7C31024B but differs in specific timing parameters and package options. The B-series designation indicates a specific generation of asynchronous SRAM optimized for low power and high density within the 3.3 V domain.

Replacement Considerations

Check for AS7C31024B variants if different speed grades are acceptable. Verify pinout compatibility with other 32-pin SOJ SRAMs before substitution.
