AS7C164A-15PCNTR

Overview

The AS7C164A-15PCNTR is a 64 Kbit (8K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a maximum access time of 15 ns and supports a parallel interface. The device functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption current of 140 mA. It is housed in a 28-pin Plastic Dual In-line Package (PDIP) and is designed for commercial temperature applications ranging from 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast 15 ns access time
• Single 5V power supply compatibility
• Commercial temperature rating for standard environments

Applications

• General-purpose data storage in embedded systems
• Cache memory buffers for microprocessors
• Industrial control system logic storage

Procurement Notes

Verify the specific suffix 'PCNTR' against official datasheets to confirm package type and reel specifications. Ensure the component meets RoHS requirements if applicable to your assembly process. Confirm humidity sensitivity levels prior to soldering to prevent damage during reflow processes.

Selection Notes

Select this part when a compact 64 Kbit SRAM solution is required for 5V logic systems. The PDIP package suits through-hole mounting needs. Compare against TSOP or SOJ variants if surface-mount technology is preferred for space-constrained designs.

Part Context

This component belongs to the AS7C164A series of high-speed SRAMs. It provides non-volatile-free temporary storage for digital circuits. The 15ns speed class ensures rapid data retrieval suitable for synchronous-like performance in asynchronous buses.
