Cypress CY7C63722/23 CY7C63743 enCoRe USB Peripheral Controller Handbook

About this manual

The enCoRe™ USB family combines low‑speed USB and PS/2 functionality in a single microcontroller. Cypress provides an internal crystal‑less oscillator, a 3.3 V regulator for the USB pull‑up resistor, and configurable GPIO pins, allowing designers to minimize external components.

The handbook covers the functional overview, pin assignments, programming model, instruction set, memory organization, clocking, reset behavior, and peripheral interfaces such as USB, PS/2, SPI, and timers. Detailed diagrams and tables give designers the information needed to integrate the CY7C63722, CY7C63723, and CY7C63743 devices into their products.
