AS7C31025B-15JCNTR

Overview

The AS7C31025B-15JCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory (SRAM) 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 Small Outline J-Lead (SOJ) surface-mount package. Maximum power consumption is specified at 60 mA. It supports commercial operating temperatures from 0°C to +70°C.

Feature Summary

• Asynchronous parallel data transfer architecture
• Single 3.3 V power supply operation
• Surface-mount SOJ packaging for compact integration

Applications

• Embedded system data storage
• Industrial control logic buffering
• Consumer electronics memory modules

Procurement Notes

Verify the specific suffix 'JCNTR' confirms the tape-and-reel packaging format, distinct from tube variants. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm the 32-SOJ footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 15 ns access speed is required for 1 Mbit capacity applications. It is suitable for designs needing a 32-pin SOJ form factor. Consider the 60 mA current draw for power budget calculations. Verify compatibility with 3.3 V logic levels in the target system environment.

Part Context

This part belongs to the AS7C31025B series of high-speed SRAMs. The 'TR' suffix indicates tape-and-reel packaging, optimized for automated surface-mount assembly processes. It shares core electrical specifications with other variants in the family but differs in physical delivery format.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio that match the 15 ns speed grade and 32-SOJ package dimensions.
