AS7C1025B-12TJCNTR

Overview

The AS7C1025B-12TJCNTR 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 component features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface mount technology. The device supports single data rate operation and functions reliably within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous SRAM architecture providing fast 12 ns access times for rapid data retrieval
• Parallel interface configuration supporting standard digital logic connections
• Surface mount SOJ-32 packaging optimized for automated assembly processes

Applications

• Embedded systems requiring non-volatile-like speed without power retention
• Industrial control units operating within commercial temperature limits
• Consumer electronics utilizing 5V logic families

Procurement Notes

Verify the specific suffix TJCNTR against official datasheets to confirm the reel packaging format and RoHS compliance status. Ensure the 5V operating voltage aligns with the target system design. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when a 128K x 8 organization is required with 5V compatibility. The 12 ns speed suits applications needing moderate performance. Consider the SOJ-32 footprint during PCB layout. Verify thermal requirements against the 0°C to +70°C operational range before integration into the final product design.

Part Context

This part belongs to the AS7C1025B series of high-speed asynchronous SRAMs. It shares architectural similarities with other members like the AS7C1024B but differs in specific organizational parameters and packaging options. The series targets general-purpose memory applications requiring reliable data storage and retrieval speeds.
