Cypress CY7C63722C CY7C63723C CY7C63743C USB Combination Low-Speed USB and PS/2 Peripheral Controller Manual
This document describes the enCoRe™ USB Combination Low‑Speed USB and PS/2 Peripheral Controller, a dual‑mode device that can operate as either a USB or PS/2 interface without external components. It highlights the internal 3.3 V regulator, built‑in oscillator, and configurable GPIO that simplify system design for mice, gamepads, joysticks, and similar peripherals.
Technical sections cover the 8‑bit RISC core, memory organization (256 B RAM, 8 KB EPROM), pin‑out diagrams, programming model, instruction set, and detailed I/O register maps. The manual also provides USB compliance information, timing diagrams, and guidance for using the optional external 6 MHz resonator.
