This document is the user manual of CY7C65013 and CY7C65113 USB hub.
This manual describes the Cypress CY7C65013 and CY7C65113 devices, which combine an 8‑bit USB‑optimized microcontroller with an integrated USB hub. It covers functional overview, pin assignments, register maps, programming model, clocking, reset, suspend mode, GPIO ports, timers, I²C interface, and USB hub operation.
Key specifications include a 4.0 V‑5.5 V operating voltage range, 0 °C‑70 °C temperature range, 256 bytes of RAM, 8 KB of PROM, and support for up to seven downstream USB ports (CY7C65013) or four (CY7C65113). The document also provides absolute maximum ratings, electrical characteristics, and package diagrams.
| Operating voltage | 4.0 V to 5.5 V DC |
|---|---|
| Operating temperature | 0 °C to 70 °C |
| RAM | 256 bytes |
| Downstream USB ports | Up to 7 (CY7C65013) or 4 (CY7C65113) |
| GPIO sink current (typical) | 7 mA per pin (Ports 0‑2), 12 mA per pin (Port 3) |
| Maximum power dissipation | 500 mW |
GPIO Port 3 pins can sink up to 12 mA per pin (typical).
The device uses a 6 MHz external crystal, a 12 MHz internal CPU clock, and a 48 MHz internal hub clock.
The maximum power dissipation is 500 mW.
