AS7C1024B-20JCNTR

Overview

The AS7C1024B-20JCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 20 ns. The device utilizes a parallel interface and is housed in a surface-mount SOJ-32 package. Maximum power consumption is specified at 90 mA, and it supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Asynchronous operation for flexible system integration
• High-speed data access capabilities
• Surface-mount packaging for automated assembly

Applications

• General-purpose data storage in embedded systems
• Cache memory applications in microcontroller designs
• Industrial control system data buffering

Procurement Notes

Verify the specific suffix JCNTR against official datasheets to confirm package type and reel specifications. Ensure voltage requirements match the target circuit design. Check RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this component when a 128K x 8 organization is required with 20 ns speed. Compare against other AS7C1024B variants for different access times or packages. Confirm compatibility with 5V logic levels and available board space for the SOJ-32 footprint.

Part Context

This part belongs to the AS7C1024B series of fast asynchronous SRAMs. It shares architectural similarities with other members like the AS7C1024B-15 but offers a slower access time. The series is designed for general-purpose memory applications requiring non-volatile-like speed without the complexity of flash programming.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as the AS7C1024B-15JCNTR for faster performance. Verify that any substitute maintains the same 5V supply requirement and SOJ-32 package dimensions.
