AS7C31025B-15JCN

Overview

The AS7C31025B-15JCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 15 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports single data rate operation and is rated for commercial temperature applications, functioning reliably between 0°C and +70°C.

Feature Summary

• Asynchronous parallel interface architecture for standard memory control
• Single data rate operation with fast access speeds
• Surface-mount 32-pin SOJ packaging for compact board integration

Applications

• Embedded systems requiring non-volatile-like speed without retention
• Industrial control units operating within commercial temperature ranges
• Consumer electronics utilizing 3.3V logic levels
• General-purpose buffer memory in microcontroller-based designs

Procurement Notes

Verify the specific suffix JCN confirms the 32-pin SOJ package and commercial temperature grade against your schematic requirements. Confirm that the 3.0 V to 3.6 V supply range aligns with your system's power rails. Ensure design compatibility with the asynchronous parallel interface timing specifications before finalizing procurement orders.

Selection Notes

Select this component when a 1 Mbit capacity is required with 15 ns access speed in a 32-pin SOJ form factor. It is suitable for designs powered by 3.3 V logic families. Consider alternative packages or voltage variants if industrial temperature ratings or different pin counts are necessary for the target application environment.

Part Context

This part belongs to the AS7C31025B series of high-speed SRAMs from Alliance Memory. The series offers various access times and voltage options. The AS7C31025B-15JCN specifically targets commercial applications with its 0°C to +70°C rating and 3.3V operation, distinguishing it from industrial-grade or 5V variants within the broader product line.

Replacement Considerations

Direct substitutes include other AS7C31025B variants with matching 15 ns speed and 3.3V operation, such as AS7C31025B-15TIN, provided the TSOP-II package is acceptable. Verify pinout compatibility and electrical characteristics before swapping.
