This data sheet describes the features and characteristics of the enCoRe™ USB Combination Low-Speed USB and PS/2 Peripheral Controller CY7C63722, CY7C63723 and CY7C63743. This is a flexible, cost-effective solution for applications that combine PS/2 and low-speed USB, such as mice, game-pads, joysticks and many others.
The enCoRe™ controller combines low‑speed USB and PS/2 interfaces in a single chip, eliminating the need for external crystals, pull‑up resistors, or separate mode‑switching components. It includes an internal 3.3 V regulator for the USB pull‑up and configurable GPIO pins for flexible I/O.
The document provides a functional overview, pin‑out diagrams, programming model details, memory organization, I/O register summary, and clocking options, along with electrical specifications such as operating voltage, temperature range, and GPIO drive capability.
