AS6C6264A-70SINTR

Overview

The AS6C6264A-70SINTR is an asynchronous static random access memory (SRAM) manufactured by Alliance Memory. It provides a total storage capacity of 64 kbit, organized as 8K words by 8 bits. The device features a typical access time of 70 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes CMOS technology for low power consumption, with a typical operating current of 10 mA and standby current below 2 μA at temperatures up to 70 °C. The component is available in a surface-mount SOP-28 package.

Feature Summary

• Low power CMOS construction ensures minimal energy usage during active operations and standby modes.
• Common data inputs and outputs simplify circuit design by sharing pin assignments.
• Three-state outputs allow direct interfacing with system buses without additional buffering.
• Automatic power reduction occurs during extended read or write cycles to enhance efficiency.

Applications

• Embedded systems requiring fast, non-volatile-like temporary data storage
• Industrial control units operating within standard temperature ranges
• Consumer electronics utilizing 5V logic interfaces

Procurement Notes

Verify the specific suffix 'SINTR' against official manufacturer documentation to confirm the exact package type and tape-and-reel configuration. Ensure the required supply voltage aligns with the 4.5V to 5.5V specification. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 64 kbit SRAM with 70 ns speed is required for 5V applications. Consider the SOP-28 surface-mount package for space-constrained designs. Evaluate power requirements against the 10 mA active and <2 μA standby currents. Compare against other AS6C6264 variants if different access times or voltage ranges are needed.

Part Context

This part belongs to the AS6C6264A family of low-power CMOS SRAMs from Alliance Memory. The series offers various access speeds and packaging options to suit different embedded memory needs. The AS6C6264A specifically targets applications needing reliable static RAM with TTL/CMOS compatibility and robust ESD protection exceeding 2000 V.

Replacement Considerations

Check for AS6C6264A-70SCNTR or AS6C6264A-70SIN as potential functional equivalents within the same family. Verify pinout compatibility and electrical specifications before substitution. Ensure any replacement matches the 8K x 8 organization and 5V operation requirements.
