AS6C8008A-45ZINTR

Overview

The AS6C8008A-45ZINTR is an asynchronous static random-access memory (SRAM) device manufactured by Alliance Memory. It provides a total storage capacity of 8 Mbit, organized as 1M words by 8 bits. The component features a maximum access time of 45 ns and operates within a supply voltage range of 2.7 V to 3.6 V. It utilizes a parallel interface with a 20-bit address bus and is housed in a 44-pin TSOP II package. The device supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation with fast 45 ns access time for efficient data retrieval
• Low power consumption design suitable for battery-operated applications
• Industrial temperature rating ensuring stability in harsh environments
• Single 3.3V power supply compatibility simplifying system integration

Applications

• Industrial control systems requiring reliable non-volatile-like performance
• Embedded systems needing high-speed local data buffering
• Telecommunications equipment utilizing standard SRAM interfaces
• Automotive electronics operating within specified temperature limits

Procurement Notes

Verify the specific suffix ZIN against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Ensure the voltage range matches the target circuit's 3.3V logic levels. Confirm pinout compatibility with existing PCB layouts before procurement. Check for any recent lifecycle notices regarding obsolescence or replacement recommendations from the manufacturer.

Selection Notes

Select this component when an 8 Mbit capacity with 45 ns speed is required in a 44-pin form factor. It is appropriate for designs constrained by a 3.3V supply rail rather than the wider 2.7V-5.5V range found in other series variants. Consider the TSOP II package dimensions for board space constraints. Evaluate thermal requirements against the industrial grade specification for long-term reliability.

Part Context

This part belongs to the AS6C8008A series of low-power CMOS static RAMs. It represents a specific variant optimized for 3.3V operation compared to broader voltage family members. The AS6C8008A series is designed to replace older generation SRAMs while offering improved power efficiency. It maintains pin compatibility with industry-standard equivalents for easier migration.

Replacement Considerations

Check for AS6C8008-45ZIN if a wider voltage range is acceptable. Verify AS6C8008B-45ZIN for potential newer die revisions. Consult official substitution guides for pin-compatible alternatives with different access times.
