AS7C1025B-10TJCNTR

Overview

The AS7C1025B-10TJCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates on a single 3.3V power supply with a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports commercial temperature ranges and features low-power CMOS technology for efficient data retention and read operations.

Feature Summary

• Asynchronous operation with fast 10 ns access times
• Single 3.3V voltage supply capability
• Surface-mount 32-pin SOJ packaging

Applications

• Embedded systems requiring non-volatile-like speed without battery backup
• Industrial control units operating within commercial temperature limits
• Consumer electronics utilizing 3.3V logic levels

Procurement Notes

Verify the specific suffix 'TJCNTR' against official datasheets to confirm tape-and-reel packaging and commercial grade designation. Ensure compatibility with 3.3V logic families. Check for RoHS compliance status as indicated in current manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a 128K x 8 organization is required with 10 ns performance at 3.3V. Compare against the AS7C1024 series if 5V operation is acceptable, or consider industrial grade variants if extended temperature ranges are necessary. Confirm pinout compatibility with existing PCB layouts using the SOJ-32 footprint.

Part Context

This part belongs to the AS7C1025B family of high-speed SRAMs. It shares architectural similarities with other members like the AS7C1024B but differs in supply voltage requirements. The 'TJCNTR' suffix indicates specific packaging and environmental classifications distinct from tube-packaged or industrial-grade equivalents within the same product line.

Replacement Considerations

Direct substitutes include other 1M-bit 3.3V SRAMs in SOJ-32 packages such as the AS7C1025B-12TJCNTR for slower speeds. Verify electrical parameters carefully when cross-referencing with generic 128Kx8 SRAMs from other manufacturers.
