General-

purpose ports

General purpose I/O ports (37 : CMOS (7 of 3 V ports ) , 4 : Nch open drain)

USB hub

Upstream port : 1 channel

Downstream port : 5 channels (One is dedicated to an internal function.)

Port power supply control method : By individual port

Allows selection between own power supply and bus power supply

USB function

Supports full speed : when using hub

Supports full and low speeds : when using function

End point max 4

Built-in DMAC (Can be set to DMA transfer to the internal RAM)

PWM timer 8-bit PWM timer operation 2 channels (can also be used as a PPG 1 channel timer)

UART SIO

SIO

I2C interface

Allows switching between UART (clock-synchronous/asynchronous data transfer allowed)

and SIO (simple serial transfer).

SIO (simple serial) × 2 channels (3 V)

One channel. Supports Phillips I2C bus standards. Uses a 2-wire protocol for communications

with other devices.

Timebase

timer

21-bit timebase timer

Clock output Allows clock output of 12 MHz* and 6 MHz* (3 V)

Standby mode Sleep mode and Stop mode

* : When external supply clock is at 6 MHz.
