AS7C1024B-15JCNTR

Overview

The AS7C1024B-15JCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within 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 supports single data rate (SDR) storage. It is housed in a 32-pin SOJ package designed for surface-mount technology. The component 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 for efficient data retrieval
• Single data rate architecture supporting standard parallel interface protocols
• Surface-mount design in a compact 32-pin SOJ package for automated assembly

Applications

• Embedded systems requiring non-volatile-like rapid data buffering
• Industrial control units operating within commercial temperature limits
• Consumer electronics utilizing 3.3V logic levels

Procurement Notes

Verify the specific suffix JCNTR against official datasheets to confirm the SOJ-32 package and reel packaging configuration. Ensure the 3.0V to 3.6V voltage range aligns with target system power rails. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a 128K x 8 organization is required with 15 ns speed at 3.3V logic levels. Compare against the AS7C31024B series for identical specifications but different pinout or package options. Consider thermal management requirements given the 90 mA maximum current draw during active operation.

Part Context

This part belongs to the AS7C1024B family of 1 Mbit SRAM devices. Variants within this series differ primarily in access speed, supply voltage tolerance, and physical package type. The JCNTR designation specifically identifies the 15 ns speed grade, 3.3V operation, and tape-and-reel delivery format.

Replacement Considerations

AS7C31024B-15JCNTR offers equivalent electrical performance with potential pin-compatible alternatives depending on specific package variations.
