This document is the datasheet of CY7C66013C, CY7C66113C produced by Cypress Semiconductor Corporation
The CY7C66013C and CY7C66113C are full‑speed (12 Mbps) USB peripheral microcontrollers that integrate a USB hub, making them ideal for compound USB devices such as keyboard hubs. They provide an 8‑bit Harvard‑architecture CPU, multiple GPIO ports, a DAC port, I2C/HAPI interfaces, and a 12‑bit free‑running timer.
This manual covers the device features, functional overview, pin assignments, register summaries, programming model, clocking, reset, suspend mode, interrupt handling, USB operation, hub control, electrical and switching characteristics, ordering information, and package design notes. It also includes schematic examples and absolute maximum ratings.
