AS7C1024B-20TJINTR

Overview

The AS7C1024B-20TJINTR 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 80 mA. The device features a 20 ns access time and utilizes a parallel interface. It is housed in a 32-pin TSOP I package designed for surface-mount technology. The component supports single data rate operations and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

Asynchronous operation with parallel interface for direct system integration
Industrial temperature rating ensuring reliability in harsh environments
Surface-mount TSOP I packaging optimized for space-constrained designs

Applications

Industrial control systems requiring robust memory solutions
Embedded applications operating in extreme temperature conditions
Data buffering in high-speed parallel communication interfaces

Procurement Notes

Verify the specific suffix TJINTR against official datasheets to confirm the tape-and-reel packaging format, as standard variants may use tubes. Ensure the voltage supply matches the 4.5V–5.5V requirement strictly. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a 128K x 8 organization is required with a 20 ns speed grade. It is suitable for designs needing industrial temperature stability (-40°C to +85°C). Compare against the AS7C1024B-20TJIN if tube packaging is preferred over reel packaging for the same electrical specifications.

Part Context

This part belongs to the AS7C1024B series of 1 Mbit SRAMs. It shares core electrical characteristics with other variants like AS7C1024B-20TJIN but differs in packaging configuration. The series is designed for general-purpose memory applications requiring fast asynchronous access times.
