AS7C1024B-12TCNTR

Overview

The AS7C1024B-12TCNTR 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 with a maximum current consumption of 100 mA. The device features a 12 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 operations and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast 12 ns access time
• CMOS SRAM technology for high reliability
• Surface mount SOJ-32 packaging

Applications

• General-purpose data storage
• Buffer memory applications
• Cache memory systems

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging, distinct from tube variants. Confirm RoHS compliance status through official documentation. Ensure the operating voltage matches system requirements of 4.5V to 5.5V. Check for humidity sensitivity classification prior to soldering. Validate the manufacturer part number against the latest datasheet revision.

Selection Notes

Select this component when a 128K x 8 organization is required in a 32-pin SOJ package. Choose this variant over industrial versions if operation is limited to commercial temperatures. Consider the tape and reel format for automated assembly processes. Verify power consumption limits against system thermal constraints.

Part Context

This part belongs to the AS7C1024B series of 1 Mbit SRAMs. It shares core specifications with other suffixes like TJCN but differs in packaging and moisture sensitivity handling. The series provides standard asynchronous SRAM functionality for embedded systems requiring non-volatile-like retention without battery backup.

Replacement Considerations

AS7C1024B-12TJCN offers identical electrical performance in a tube package. AS7C1024B-12JIN provides an extended industrial temperature range.
