Overview
The AS7C31025B-10TJCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3 V to 3.6 V, with a maximum power consumption of 70 mA. The device features a 10 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 operation and functions reliably within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Asynchronous SRAM architecture providing fast 10 ns access times for efficient data retrieval.
Applications
- Embedded systems requiring non-volatile-like persistence without refresh cycles
- Industrial control units operating within commercial temperature limits
- Consumer electronics utilizing 3.3V logic interfaces
Procurement Notes
Verify the specific suffix TJCN against the manufacturer's datasheet to confirm pinout compatibility and RoHS compliance status. Ensure the design accommodates the SOJ-32 footprint and SMD mounting requirements. Confirm that the system power supply remains strictly within the 3 V to 3.6 V operational window to prevent electrical overstress or functional failure during high-speed asynchronous operations.
Selection Notes
Select this component when a 128K x 8 organization is required with 10 ns speed performance. It is suitable for designs constrained to 3.3V logic levels and commercial temperature environments. Consider the SOJ-32 package dimensions for PCB layout constraints. Verify that the 70 mA current draw aligns with the system's power budget and thermal management capabilities.
Part Context
This part belongs to the AS7C31025B series of asynchronous SRAMs from Alliance Memory. It shares core specifications with variants like the AS7C31025B-10JCN, differing primarily in packaging or minor manufacturing revisions. The series targets applications needing reliable, low-latency memory storage in compact surface-mount form factors.
Replacement Considerations
The AS7C31025B-10JCN is a documented alternative within the same series. Verify pin-to-pin compatibility and identical electrical parameters before substitution. Ensure the replacement variant meets the same SOJ-32 package and commercial temperature requirements.
