Overview
The AS7C31024B-12TJCNTR 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 voltage range of 3.0V 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 package. It supports surface-mount installation and functions within a commercial temperature range of 0°C to +70°C, with a maximum operating current of 65mA.
Feature Summary
- Asynchronous SRAM architecture providing fast data access for embedded systems
- Single 3.3V power supply operation for low-voltage compatibility
- High-density 1 Mbit storage organized as 128K words by 8 bits
- Surface-mountable 32-pin Small Outline J-Lead package design
Applications
- Embedded control systems requiring non-volatile-like rapid data retention
- Industrial automation equipment with standard voltage requirements
- Consumer electronics utilizing 3.3V logic interfaces
- Communication devices needing fast buffer memory capabilities
Procurement Notes
Verify the specific suffix TJCNTR against official datasheets to confirm the tape-and-reel packaging format and lead type. Ensure the 3.3V operating voltage aligns with target system designs. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.
Selection Notes
Select this component when a 12ns access speed and 3.3V operation are required for 128Kx8 memory configurations. Compare against the TSN variant if TSOP packages are preferred over SOJ forms. Evaluate thermal management needs within the 0°C to +70°C commercial range for final deployment environments.
Part Context
This part belongs to the AS7C31024B series of high-speed asynchronous SRAMs from Alliance Memory. It shares core electrical specifications with other variants in the family but differs in physical packaging and reel configuration. The series is designed for general-purpose memory applications requiring reliable data storage without refresh cycles.
