Overview
The AS7C31024B-15TJCN is a 1-Mbit (128K x 8) static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 15 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package designed for surface mount technology. It supports single data rate operations and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 60 mA.
Feature Summary
- Provides high-speed asynchronous data access with a 15 ns cycle time
- Operates on a standard 3.3 V power supply rail
- Utilizes a compact 32-pin small outline J-leaded package for board integration
Applications
- Embedded systems requiring fast local data storage
- Industrial control units operating in commercial environments
- Consumer electronics utilizing 3.3 V logic levels
Procurement Notes
Verify the specific suffix TJCN confirms the 32-pin SOJ package and commercial temperature grade against official datasheets. Confirm RoHS compliance status through manufacturer documentation prior to finalizing procurement specifications. Ensure design compatibility with the required surface mount footprint and pin configuration.
Selection Notes
Select this component when a 128K x 8 organization is required alongside 15 ns performance. The 3.3 V operation makes it suitable for modern low-voltage digital circuits. Consider the SOJ package constraints for PCB layout compared to TSOP or BGA alternatives if space is limited.
Part Context
This part belongs to the AS7C31024B series of SRAM devices from Alliance Memory. The series offers various speed grades and packaging options to accommodate different system requirements while maintaining consistent 1-Mbit capacity and 3.3 V operational standards across the product line.
Replacement Considerations
Check for other suffixes within the AS7C31024B family that may offer different packages or temperature ranges. Verify pinout compatibility before substituting with similar 128K x 8 SRAMs from other manufacturers.
