AS6C6264-55SCNTR

Overview

The AS6C64-55SCNTR is an asynchronous static random-access memory (SRAM) integrated circuit manufactured by Alliance Memory, Inc. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device features a parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 2.7 volts to 5.5 volts and supports surface-mount installation in a SOP-28 package. The component is designed for single data rate applications.

Feature Summary

• Asynchronous operation utilizing a parallel interface for data transfer
• CMOS technology enabling low power consumption characteristics
• Wide operating voltage compatibility supporting 2.7V to 5.5V ranges

Applications

• General-purpose data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Data storage in industrial control equipment

Procurement Notes

Verify the specific suffix SCNTR indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required SOP-28 surface-mount footprint for PCB layout compatibility.

Selection Notes

Select this component for designs requiring 64Kbit volatile memory with fast 55ns access speeds. The wide voltage range allows flexibility in power supply design across different logic families. Verify that the SOP-28 package dimensions align with available board space constraints.

Part Context

This part belongs to the AS6C6264 series of 64K-bit CMOS SRAMs from Alliance Memory. The series offers various speed grades and packaging options including through-hole and surface-mount configurations. The AS6C6264-55SCNTR specifically denotes the 55ns speed grade in a reel-packaged SOP-28 form factor.

Replacement Considerations

AS6C6264-55SCN is the tube-packaged equivalent of the same electrical specification. AS6C6264-55PIN is a pin-compatible alternative in a DIP package. Verify package type differences before substitution.
