AS7C1026B-12JCNTR

Overview

The AS7C1026B-12JCNTR 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 and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package suitable for surface mount technology. It supports single data rate operations and functions reliably across commercial temperature ranges from 0°C to +70°C, with a maximum power supply current of 100 mA.

Feature Summary

• Asynchronous operation with fast 12 ns access times
• Single data rate parallel interface architecture
• Surface mount compatible 32-pin SOJ packaging

Applications

• General-purpose data storage in embedded systems
• Cache memory buffers for microprocessors
• Industrial control system data logging

Procurement Notes

Verify the specific suffix JCNTR indicates reel packaging distinct from tube variants. Confirm RoHS compliance status through official documentation before integration. Ensure voltage levels match the 4.5 V to 5.5 V operational requirement. Check humidity sensitivity handling procedures during assembly. Validate pinout compatibility with existing PCB footprints.

Selection Notes

Select this component when 128K x 8 organization fits the address space requirements. Choose the 12 ns speed grade for timing-sensitive asynchronous interfaces. Opt for the SOJ-32 package if surface mount reliability is required. Consider the 5V operating voltage against available system rails. Evaluate the 100 mA current consumption against thermal constraints.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit SRAMs. It shares architectural similarities with other devices in the family but differs in package type and speed grade. The TR suffix typically denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

AS7C1026B-12JIN serves as a tube-packaged alternative with identical electrical specifications.
