AS7C31024B-15TJCNTR

Overview

The AS7C31024B-15TJCNTR is a 1 Mbit (128K x 8) asynchronous static random access memory manufactured by Alliance Memory. It operates at a maximum access time of 15 ns and supports a voltage range of 3.0 V to 3.6 V. The device features a maximum supply current of 60 mA and functions within a commercial temperature range of 0°C to +70°C. It utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package.

Feature Summary

• Asynchronous operation for flexible system integration
• CMOS technology ensuring low power consumption
• Commercial grade reliability for standard operating environments

Applications

• General-purpose data storage in embedded systems
• Buffer memory for microprocessor-based applications
• Cache memory in industrial control units

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging, distinct from tube packaging variants like 'CN'. Confirm RoHS compliance status with the manufacturer's latest documentation. Ensure the SOJ-32 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 15 ns access speed is required for 1 Mbit capacity. Compare against faster variants if higher throughput is needed. Consider the SOJ package dimensions for board space limitations. Verify voltage compatibility with the 3.3 V system rail.

Part Context

This part belongs to the AS7C31024B series of high-performance CMOS SRAMs. The series offers various access times and package options to suit different design requirements. The TR suffix typically denotes reel packaging for automated assembly processes.

Replacement Considerations

Check for pin-compatible alternatives within the same series, such as AS7C31024B-15TCN, noting that package type differences may require adapter solutions or redesign.
