AS7C1025B-15TJCNTR

Overview

The AS7C1025B-15TJCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 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 reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 90 mA.

Feature Summary

• Asynchronous operation with fast 15 ns access times
• Single data rate architecture for standard memory interfacing
• Surface-mount compatible 32-pin SOJ packaging

Applications

• General-purpose data storage in embedded systems
• Cache memory applications in microcontroller-based designs
• Buffering in industrial control equipment

Procurement Notes

Verify the specific suffix 'NTR' against the manufacturer's official datasheet to confirm reel packaging specifications and moisture sensitivity levels. Ensure the ordering quantity aligns with the factory pack size requirements. Cross-reference the RoHS status directly with the component documentation prior to procurement to ensure regulatory compliance for the target assembly process.

Selection Notes

Select this component when a 1 Mbit capacity with 15 ns speed is required in a 5V logic environment. The SOJ-32 package suits applications needing surface-mount integration without the pin count of TSOP variants. Verify that the 90 mA current draw fits the system power budget and that the commercial temperature range meets the operational environmental constraints.

Part Context

This part belongs to the AS7C1025B series of high-speed CMOS SRAMs. It shares architectural similarities with other members like the AS7C1024B but differs in organization and package options. The series is designed for general-purpose use where non-volatile retention is not required, offering rapid read/write cycles compared to flash technologies.

Replacement Considerations

Check for direct substitutes such as the AS7C1024B-15TJCNTR or AS7C1026B-15TCN if pinout compatibility allows. Verify that alternative packages maintain the same 128K x 8 organization and 15 ns timing characteristics.
