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 I2C-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
