AS7C31025B-12TJCN

Overview

The AS7C31025B-12TJCN is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3V to 3.6V and features a maximum access time of 12ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ surface-mount package. It supports single-data-rate operations and functions within an industrial temperature range from -40°C to +85°C, with a maximum power consumption of 65mA.

Feature Summary

• Asynchronous operation for flexible system integration
• Industrial-grade thermal stability across extended temperature ranges
• Single-voltage power supply compatibility

Applications

• Industrial control systems requiring reliable data retention
• Embedded applications operating in extreme environmental conditions
• High-speed buffering in consumer electronics

Procurement Notes

Verify the specific suffix 'TJCN' against official manufacturer documentation to confirm the exact package type and reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a 128K x 8 organization is required alongside a 12ns access speed. The SOJ-32 package is suitable for space-constrained surface-mount designs. Consider the -40°C to +85°C operating range if the application environment exceeds standard commercial limits. Verify that the 3.3V nominal supply aligns with the system's power architecture.

Part Context

This part belongs to the AS7C31025B series of high-speed SRAMs. It shares architectural similarities with other members like the AS7C31024B but differs in packaging and temperature ratings. The series is designed for general-purpose memory applications where fast read/write cycles are critical for system performance.

Replacement Considerations

Check for direct pin-compatible alternatives such as the AS7C31025B-12JCN or AS7C31025B-12TCN. Confirm that substitute parts match the 12ns access time and 3.3V operating voltage. Verify package dimensions and lead configurations to ensure mechanical fit without PCB redesign.
