Overview
The AS7C31025B-15TJCN is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates on a single 3.3V power supply with a maximum access time of 15ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package suitable for surface-mount installation. It supports standard SDR storage types and functions within commercial temperature ranges.
Feature Summary
- Provides high-speed asynchronous data access for general-purpose memory applications
- Operates efficiently on a single 3.3V power supply to reduce system complexity
- Features a compact 32-pin SOJ package designed for surface-mount technology integration
Applications
- General-purpose data buffering in embedded systems
- Cache memory implementation in microcontroller-based designs
- Industrial control system data storage
Procurement Notes
Verify the specific suffix 'TJCN' against official datasheets to confirm the 32-pin SOJ package and 3.3V operation parameters. Ensure compatibility with existing board layouts requiring this specific form factor. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement decisions.
Selection Notes
Select this component when a 128K x 8 organization is required with 15ns speed performance. It is suitable for designs needing a 3.3V supply and surface-mount assembly. Compare pinout and electrical characteristics against alternative SRAM families to ensure direct fitment without circuit redesign.
Part Context
This part belongs to the AS7C31025B series of fast asynchronous SRAMs from Alliance Memory. The series offers various speed grades and voltage options. The AS7C31025B-15TJCN specifically targets applications requiring reliable, low-power memory solutions in a standard industrial-compatible package configuration.
Replacement Considerations
Check for updated revisions within the AS7C31025B family that may offer improved availability or minor parameter enhancements. Verify pin-to-pin compatibility with other 32-pin SOJ SRAMs if sourcing alternatives due to obsolescence concerns.
