AS6C8008-55ZIN

Overview

The AS6C8008-55ZIN is an asynchronous static random-access memory (SRAM) device manufactured by Alliance Memory. It provides a total storage capacity of 8 megabits, organized as 1 megaword by 8 bits. The component features a maximum random access time of 55 nanoseconds and operates within a supply voltage range of 2.7 volts to 5.5 volts. It utilizes a 44-pin Thin Shrink Small Outline Package (TSOP II) for surface-mount installation. The device supports an industrial operating temperature range from -40 degrees Celsius to +85 degrees Celsius.

Feature Summary

• Asynchronous parallel interface architecture
• Low power consumption design
• Industrial temperature grade operation

Applications

• Embedded systems requiring non-volatile-like data retention without refresh cycles
• Industrial control units needing fast random access memory
• Consumer electronics with standard logic voltage requirements

Procurement Notes

Verify the specific suffix ZIN against official datasheets to confirm package dimensions and lead-free compliance status. Ensure the ordering code matches the required 55ns speed grade and 44-pin TSOP form factor. Confirm availability through authorized distributors as stock levels fluctuate. Check for RoHS directive adherence if environmental regulations apply to your region.

Selection Notes

Select this part when 8Mbit capacity and 55ns access speed are required in a compact surface-mount footprint. Compare against AS6C8008A variants for potential voltage or speed differences. Consider the 44-pin TSOP II size constraints relative to PCB layout space. Evaluate power dissipation limits at maximum operating temperatures before finalizing the design.

Part Context

This component belongs to the AS6C8008 series of low-power asynchronous SRAMs. It serves as a high-speed buffer or cache memory in digital circuits. The series offers various speed grades and packaging options to suit different system integration needs while maintaining compatibility with standard CMOS logic families.

Replacement Considerations

Check for AS6C8008B-55ZIN for potentially updated manufacturing revisions. Verify pinout compatibility with AS6C8008A-55ZIN before substitution.
