Product details

Obsolete 16Kbit asynchronous SRAM in a 20-DIP footprint

The CY7C168A-20PXC: Housed in a 20-pin DIP (0.300", 7.62mm) package, this part was designed for legacy 5 V logic systems requiring fast scratchpad or configuration storage.

In a system with a 5 V bus running at 25 MHz (40 ns cycle), this leaves 20 ns of margin for address decoding, buffer delays, and setup time to the controller — adequate for most legacy glue-logic designs but tight if cascading multiple memory banks without pipeline registers.

Sourcing is limited to surplus inventory and broker channels.

The 20-DIP (0.300", 7.62mm) through-hole package suits socketed prototyping or retrofit into existing PCB layouts with a 0.3" row spacing.

Frequently asked questions

What is the replacement for CY7C168A-20PXC?

Buyers need a drop-in or functional replacement when the original is obsolete to avoid redesign.

Is CY7C168A-20PXC obsolete and what are the lifecycle details?

Engineers and buyers must know if the part is end-of-life to plan for availability or redesign.

Where can I buy CY7C168A-20PXC with stock and price?

Transactional intent: sourcing buyers need immediate inventory and pricing to order.

What is the pin configuration of CY7C168A-20PXC?

Design engineers validating fit require pinout to check layout compatibility.

Are there equivalents or cross references for CY7C168A-20PXC?

Comparison intent: maintenance techs and brokers need alternative part numbers for replacement.

What are the key specifications of CY7C168A-20PXC?

Quick spec lookup (memory size, access time, voltage) is the first step for all buyer types.
