This document describes the features and characteristics of the Universal Serial Bus Microcontroller CY7C63001C and CY7C63101C models produced by Cypress Semiconductor Corporation. It is a low-cost solution for low-speed USB peripherals such as mouse, joystick, and gamepad.
The Cypress CY7C63001C and CY7C63101C are low‑cost 8‑bit RISC microcontrollers with an integrated 1.5 Mbps USB interface, designed for low‑speed peripherals such as mouse, joystick and gamepad. The document provides a functional overview, pin configurations, memory organization, and detailed I/O register descriptions.
Key sections describe the power‑on, watchdog and USB reset behavior, the instant‑on suspend feature, GPIO capabilities, and package options (20‑pin PDIP, 20‑pin SOIC, 24‑pin QSOP). The manual also includes timing diagrams, register maps, and package diagrams to aid hardware and firmware development.
