AS7C1024B-15JCN

Overview

The AS7C1024B-15JCN 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 utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead package designed for surface-mount technology. It supports Single Data Rate storage and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 100 mA.

Feature Summary

• Asynchronous operation with fast 15 ns access times
• Single data rate parallel interface architecture
• Surface-mount 32-pin SOJ packaging

Applications

• Embedded system memory
• Industrial control systems
• Consumer electronics devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with 5V logic levels and check humidity sensitivity handling requirements during assembly. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a 1-Mbit capacity with 15 ns speed is required in a compact surface-mount form factor. It suits designs needing standard 5V operation without complex clocking schemes. Consider thermal management for continuous high-load operations within the specified commercial temperature limits.

Part Context

This part belongs to the AS7C1024B series of SRAMs from Alliance Memory. It provides non-volatile-like retention characteristics for volatile memory applications. The series is widely used in legacy and modern embedded designs requiring reliable, low-latency data storage solutions.

Replacement Considerations

Check for pin-compatible alternatives such as the AS7C1024B-15JIN for industrial temperature ranges or different packaging options like TSOP-II if board space constraints change.
