AS7C1024B-20TJCN

Overview

The AS7C1024B-20TJCN is a 1 Mbit (128K x 8) asynchronous static random-access memory 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 20 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface-mount installation. The component supports single data rate operation and functions reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

Asynchronous parallel SRAM architecture providing 1 Mbit storage capacity
Standard 5V power supply compatibility with defined operating limits
Surface-mountable 32-pin SOJ physical form factor

Applications

Embedded systems requiring volatile data retention
Industrial control units needing fast random access
Consumer electronics utilizing standard logic levels

Procurement Notes

Verify the specific suffix TJCN against official datasheets to confirm the SOJ package type and commercial temperature rating. Ensure design compatibility with 5V logic families. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when a 5V supply is available and a 20 ns access speed meets system timing requirements. The SOJ package suits applications where surface-mount reliability is prioritized over pin-count density compared to TSOP options. Verify that the 100 mA active current draw fits the power budget constraints.

Part Context

This part belongs to the AS7C1024B series of 1 Mbit SRAMs. It shares architectural similarities with other variants but differs in package style and speed grade. The B-series designation indicates specific electrical characteristics distinct from older or newer generations within the Alliance Memory portfolio.
