Overview
The AS7C31024B-12TCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device supports a maximum supply current of 65 mA and functions in commercial temperatures from 0°C to +70°C. It utilizes a parallel interface and is housed in a surface-mount TSOP-32 package, supplied in a tape and reel configuration.
Feature Summary
- Asynchronous SRAM architecture with 1 Mbit capacity organized as 128K words by 8 bits
- Single 3.3V power supply operation compatible with standard logic levels
- Surface-mount TSOP-32 package designed for automated tape and reel processing
Applications
- Embedded data storage in consumer electronics
- Cache memory buffers in industrial control systems
- Data buffering in telecommunications equipment
Procurement Notes
Verify the complete part number against official manufacturer documentation to confirm the specific suffix indicates the tape and reel packaging format. Ensure the selected variant matches the required 12 ns access speed and commercial temperature range specifications for your design implementation.
Selection Notes
Select this component when a 1 Mbit non-volatile buffer is required in a compact surface-mount footprint. The TSOP-32 package facilitates automated assembly, while the 3.3V operating voltage ensures compatibility with modern low-power digital circuits requiring fast asynchronous data access.
Part Context
This model belongs to the AS7C31024B series of high-speed asynchronous SRAMs. It shares core electrical characteristics with variants like the AS7C31024B-12JCN but differs in physical packaging and shipping configuration. The series provides reliable static memory solutions for applications demanding rapid read and write cycles without complex refresh requirements.
Replacement Considerations
Direct pin-compatible substitutes include the AS7C31024B-12JCN and AS7C31024B-10TJCNTR, provided the packaging preference aligns with manufacturing capabilities.
