AS7C1024B-12TJCNTR

Overview

The AS7C1024B-12TJCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V with a maximum supply 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 across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast 12 ns access times
• Single data rate parallel interface architecture
• Surface-mount compatible 32-pin SOJ packaging

Applications

• General-purpose data buffering in embedded systems
• Cache memory implementation in microcontroller units
• Industrial control system data storage

Procurement Notes

Verify the specific suffix TJCNTR against official datasheets to confirm the reel packaging format and lead-free status. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 1 Mbit capacity with 12 ns speed is required in a 32-pin SOJ form factor. Confirm that the 5V logic level compatibility aligns with the system bus requirements. Verify that the commercial temperature range meets the operational environmental constraints of the intended deployment scenario.

Part Context

This part belongs to the AS7C1024B series of high-speed SRAMs. It shares architectural similarities with other variants in the family but differs in packaging and temperature ratings. The SOJ package distinguishes it from TSOP or BGA alternatives within the same memory density class.

Replacement Considerations

Direct substitutes include AS7C1024B-12TJCN for tube packaging or AS7C1024B-12JCNTR for industrial temperature ranges. Verify pinout compatibility and electrical parameters before substitution.
