Overview
The AS7C1024B-12TJCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption current of 100 mA. The device features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface mount technology. The component supports single data rate operations and functions reliably within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Asynchronous operation with 12 ns access speed
- Single data rate parallel interface architecture
- Surface mount 32-pin SOJ packaging configuration
Applications
- General-purpose data storage in embedded systems
- Cache memory implementation in microcontroller units
- Buffering applications in industrial control equipment
Procurement Notes
Verify the specific suffix TJCN against official datasheets to confirm the SOJ-32 package and commercial temperature rating. Ensure compatibility with 5V logic levels and check humidity sensitivity handling requirements during assembly. Confirm RoHS compliance status through manufacturer documentation before integration into final products.
Selection Notes
Select this component when a 5V SRAM with 12 ns latency is required in a 32-pin SOJ form factor. Compare against TSOP or DIP variants if board space constraints differ. Verify that the 100 mA active current draw fits within the system power budget and that the 0°C to +70°C operating range meets environmental specifications.
Part Context
This part belongs to the AS7C1024B series of high-speed CMOS SRAMs. It shares architectural similarities with other members like the AS7C1024B-12JIN, differing primarily in package type and temperature grade. The B-series designation indicates standard asynchronous operation without advanced power-saving modes found in newer generations.
Replacement Considerations
Direct substitutes include AS7C1024B-12JIN for industrial temperature grades or AS7C1024D-12TJINTR for tape-and-reel packaging. Verify pinout compatibility and electrical parameters before swapping.
