AS7C31024B-20TJCNTR

Overview

The AS7C31024B-20TJCNTR 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 20 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 commercial operating temperatures from 0°C to +70°C and includes RoHS compliance.

Feature Summary

• Asynchronous operation with parallel data interface
• Surface-mount 32-pin SOJ packaging
• RoHS compliant construction

Applications

• General-purpose data storage in embedded systems
• Cache memory applications in consumer electronics
• Industrial control system data buffering

Procurement Notes

Verify the specific suffix 'TJCNTR' against official datasheets to confirm the tape-and-reel packaging format and SOJ-32 footprint. Ensure the component meets the required commercial temperature range and voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a 1 Mbit capacity with 20 ns access speed is required in a compact surface-mount form factor. It is suitable for designs needing 3.3V operation and standard parallel SRAM interfaces. Consider alternative packages like TSOP if lead-free soldering constraints or different board space requirements apply.

Part Context

This part belongs to the AS7C31024B series of high-speed SRAMs. It shares architectural similarities with other variants in the family, differing primarily in access speed, package type, and manufacturing suffixes that denote specific packaging configurations such as tape-and-reel delivery.

Replacement Considerations

Cross-reference with AS7C31024B-10TJCNTR for faster 10 ns performance in the same package. Verify pin compatibility with AS7C31024B-20TCN if transitioning from tray-packaged TSOP components.
