1.0 Features

• Full-speed USB peripheral microcontroller with an integrated USB hub

—Well-suited for USB compound devices such as a keyboard hub function

• 8-bit USB optimized microcontroller

—Harvard architecture

—6-MHz external clock source

—12-MHz internal CPU clock

—48-MHz internal Hub clock

• Internal memory

—256 bytes of RAM

—8 KB of PROM

• Integrated Master/Slave I

C-compatible controller (100 kHz) enabled through General-purpose I/O (GPIO) pins

• Hardware-assisted Parallel Interface (HAPI) for data transfer to external devices

•I/O ports

—Three GPIO ports (Port 0 to 2) capable of sinking 8 mA per pin (typical)

—An additional GPIO port (Port 3) capable of sinking 12 mA per pin (typical) for high current requirements: LEDs

—Higher current drive achievable by connecting multiple GPIO pins together to drive a common output

— Each GPIO port can be configured as inputs with internal pull-ups or open drain outputs or traditional CMOS outputs

— A Digital-to-Analog Conversion (DAC) port with programmable current sink outputs is available on the CY7C66113C
