AS7C1025B-15JCNTR

Overview

The AS7C1025B-15JCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device supports a maximum power supply current of 90 mA and functions within an industrial temperature range of -40°C to +85°C. It utilizes a parallel interface and is housed in a surface-mount SOJ-32 package, supplied in tape and reel format.

Feature Summary

• Asynchronous operation for flexible system integration
• Industrial-grade temperature stability for harsh environments
• Surface-mount packaging for automated assembly

Applications

• Industrial control systems requiring reliable data storage
• Embedded applications operating under wide temperature variations
• High-speed buffering in 5V logic circuits

Procurement Notes

Verify the specific suffix JCNTR against official datasheets to confirm the SOJ-32 package and tape-and-reel delivery method. Ensure the 5V supply requirement aligns with target circuit designs. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Selection Notes

Select this component when a 128K x 8 organization is required alongside 15 ns speed at 5V. The industrial temperature rating distinguishes it from commercial variants. Verify that the SOJ-32 footprint matches the PCB layout constraints for the specific application design.

Part Context

This part belongs to the AS7C1025B series of high-speed SRAMs. It provides non-volatile-like performance without the complexity of flash programming. The series is designed for applications needing fast random access and low power consumption in standard 5V logic environments.

Replacement Considerations

Check for AS7C1025B-15JIN as a tube-packaged alternative from the same manufacturer. Verify pin compatibility and electrical specifications before substituting with other 1Mbit SRAMs.
