AS6C4008A-55ZINTR

Overview

The AS6C4008A-55ZINTR is a 4 Mbit asynchronous static random access memory organized as 512K words by 8 bits. It operates on a single power supply ranging from 2.7 V to 5.5 V with a maximum access time of 55 ns. The device features a TSOP-II-44 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Low power CMOS technology for reduced energy consumption
• Fully static operation with tri-state outputs
• TTL-compatible output drivers

Applications

• Embedded systems requiring external data storage
• Industrial control units
• Consumer electronics with parallel interface needs

Procurement Notes

Verify the specific suffix ZINTR against official Alliance Memory documentation to confirm the tape-and-reel packaging configuration. Ensure the voltage range and access speed meet system requirements before ordering, as these parameters are critical for compatibility.

Selection Notes

Select this component when a 512K x 8 organization is required in a 44-pin TSOP-II package. It serves as a low-power alternative to standard SRAMs, suitable for applications where power efficiency and wide voltage tolerance are prioritized over higher density or faster speeds.

Part Context

This part belongs to the AS6C4008 family of low-power CMOS SRAMs manufactured by Alliance Memory. The family offers various access times and package options, providing flexibility for different embedded memory applications while maintaining consistent electrical characteristics across the series.

Replacement Considerations

Check for direct pin-to-pin replacements within the same manufacturer's portfolio that share the 512K x 8 organization and TSOP-II-44 footprint. Verify that any substitute maintains the 2.7V to 5.5V operating range and 55ns access time specification.
