AS6C6264-55STCNTR

Overview

The AS6C6264-55STCNTR is a 64 Kbit asynchronous static random access memory (SRAM) manufactured by Alliance Memory, Inc. It features an 8K x 8 organization and operates within a voltage range of 2.7 V to 5.5 V. The device offers a maximum access time of 55 ns and supports parallel data interfaces. It is housed in a 28-pin thin-shrink small-outline package (TSSOP) designed for surface-mount technology. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Asynchronous operation with parallel interface
• Wide supply voltage compatibility
• Surface-mount TSSOP-28 packaging

Applications

• Embedded systems requiring volatile storage
• Industrial control units
• Consumer electronics devices

Procurement Notes

Verify the specific suffix STCNTR to confirm the TSSOP-28 package and reel tape-and-reel shipping format. Ensure the 55 ns speed grade matches system timing requirements. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this part when a compact surface-mount SRAM solution is required for 8-bit data paths. The 55 ns access speed suits moderate-frequency applications. Consider the 2.7 V minimum voltage for low-power logic compatibility. Verify thermal performance within the commercial temperature range for the intended enclosure environment.

Part Context

This component belongs to the AS6C6264 family of 64 Kbit SRAMs. Variants differ primarily by package type, such as PDIP or SOP, and speed grades. The STCNTR designation specifically identifies the thin-shrink small-outline package configuration with commercial temperature rating and reel packaging.

Replacement Considerations

Direct replacements include other AS6C6264 variants with identical electrical specifications but different packages, such as AS6C6264-55SIN for SOP-28. Cross-package substitutions require PCB layout adjustments.
