AS7C1024B-15TJCN

Overview

The AS7C1024B-15TJCN 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 power consumption of 90 mA. The device features a 15 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ surface-mount package and supports single data rate operation. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Asynchronous SRAM architecture providing fast read access times
• Single data rate parallel interface for standard digital logic integration
• Surface-mount SOJ-32 packaging suitable for automated assembly

Applications

• Embedded systems requiring non-volatile-like temporary storage
• Industrial control units needing rapid data buffering
• Consumer electronics utilizing 5V logic families

Procurement Notes

Verify the specific suffix TJCN against official datasheets to confirm the SOJ-32 package and lead-free status. Ensure the ordering code matches the required 15 ns speed grade. Confirm RoHS compliance details directly from the manufacturer's documentation prior to procurement.

Selection Notes

Select this component when a 128K x 8 organization is required with 15 ns performance. It is appropriate for designs constrained to 5V logic levels. Consider the SOJ-32 footprint during PCB layout. Verify thermal requirements against the specified commercial temperature range.

Part Context

This part belongs to the AS7C1024B series of high-speed asynchronous SRAMs. It offers a density of 1 Mbit organized as 128K words by 8 bits. The series provides various speed grades and package options to support diverse embedded memory applications across commercial environments.

Replacement Considerations

Cross-reference with other Alliance Memory parts sharing the same pinout and electrical characteristics. Verify that any substitute maintains the 128K x 8 organization and 15 ns access time specifications.
