Document #: 38-08002 Rev. *D Page 5 of 49

1.0 Features

• Full Speed USB hub with an integrated microcontroller

• 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

• I/O ports

— Two GPIO ports (Port 0 to 2) capable of sinking 7 mA per pin (typical)

— 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

— Maskable interrupts on all I/O pins

• 12-bit free-running timer with one microsecond clock ticks

• Watchdog timer (WDT)

• Internal Power-on Reset (POR)

• USB Specification compliance

— Conforms to USB Specification, Version 1.1

— Conforms to USB HID Specification, Version 1.1

— Supports one or two device addresses with up to 5 user-configured endpoints

Up to two 8-byte control endpoints

Up to four 8-byte data endpoints

Up to two 32-byte data endpoints

— Integrated USB transceivers

— Supports four downstream USB ports

— GPIO pins can provide individual power control outputs for each downstream USB port

— GPIO pins can provide individual port over current inputs for each downstream USB port

• Improved output drivers to reduce electromagnetic interference (EMI)

• Operating voltage from 4.0V to 5.5V DC

• Operating temperature from 0° to 70° C

• Available in 28-pin SOIC (-SXC) package

• Industry-standard programmer support.
