AS7C31024B-15JCNTR

Overview

The AS7C31024B-15JCNTR is a 1 Mbit (128 k 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 current of 90 mA. The device features a parallel interface and achieves an access time of 15 ns. Designed for commercial applications, it supports surface-mount installation in a SOJ-32 package. The component is supplied in a reel format and complies with RoHS standards.

Feature Summary

Asynchronous operation with a 15 ns access time for fast data retrieval
Parallel interface supporting standard digital logic connections
Commercial temperature range operation from 0°C to +70°C
Surface-mount design in a compact SOJ-32 package

Applications

Embedded systems requiring non-volatile-like speed without retention
Industrial control units operating within commercial temperature limits
Consumer electronics utilizing 5V logic families
General-purpose buffer memory in parallel bus architectures

Procurement Notes

Verify the specific suffix JCNTR against official datasheets to confirm the SOJ-32 package and reel packaging configuration. Ensure the 5V supply requirement aligns with the target circuit design, as this part does not support lower voltage levels like 3.3V. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a 128k x 8 organization is required with 15 ns performance under 5V conditions. Compare against the AS7C31024B-12TCN if 3.3V operation or TSOP packaging is preferred. Consider the AS7C31026B series for wider 16-bit data paths. Verify humidity sensitivity handling procedures due to the moisture-sensitive nature of the SOJ package.

Part Context

This SRAM belongs to the AS7C1024B/AS7C31024B family of high-speed asynchronous memories. It provides a cost-effective solution for small-scale data storage in 5V systems. The SOJ-32 form factor offers a robust leaded surface-mount option suitable for automated assembly processes in commercial-grade electronic devices.
