AS6C6264A-70PCN

Overview

The AS6C6264A-70PCN is an 8K x 8 bit asynchronous static random access memory manufactured by Alliance Memory, Inc. utilizing low power CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and features a typical access time of 70ns. The device includes three-state outputs for bus driving compatibility and TTL/CMOS-compatible inputs. It supports standard industrial temperature ranges and offers automatic power reduction during extended read or write cycles.

Feature Summary

• Low power CMOS construction with stable standby current across operating temperatures
• Three-state outputs enabling direct bus interface connections
• TTL and CMOS compatible logic levels for broad system integration
• Automatic power dissipation reduction during long read or write operations

Applications

• General purpose data storage in embedded systems
• Cache memory buffers for microprocessor applications
• Industrial control system data logging
• Communication equipment signal processing buffers

Procurement Notes

Verify the specific suffix PCN against manufacturer documentation to confirm package type and pin configuration. Ensure supply voltage requirements match the 4.5V to 5.5V specification. Confirm temperature grade aligns with operational environment needs. Check RoHS compliance status if required by regulatory standards. Validate lead times as availability may vary by region.

Selection Notes

Select this component when a reliable 64Kbit SRAM solution is required for 5V logic systems. The 70ns speed suits moderate performance applications. Consider the PDIP package for through-hole prototyping or high-reliability mounting. Compare standby current specifications against other variants if power efficiency is critical. Ensure board space accommodates the physical dimensions of the selected package style.

Part Context

This part belongs to the AS6C6264A family of low power CMOS SRAMs from Alliance Memory. The series provides non-volatile-like retention capabilities without the complexity of flash programming. It serves as a drop-in replacement for legacy 5V SRAM designs. The family emphasizes stability and wide voltage tolerance for robust industrial operation.

Replacement Considerations

Direct substitutes include AS6C6264-70PIN and AS6C6264A-70SCN. Verify pinout compatibility before substitution. Check if alternative packages meet thermal and mechanical constraints. Confirm that access times of equivalent parts do not exceed system timing budgets.
