(Continued)

• PLL clock control

The internal PLL clock circuit allows the use of low-speed clocks which are advantageous to noise character-

istics.

(6 MHz externally supplied clock : Internal system clock oscillated at 12 MHz)

• Various timers

8-bit PWM timer (can be used as either 8-bit PWM timer × 2 channels or PPG timer × 1 channel)

Internal 21-bit timebase timer

• Internal USB transceiver circuit (Compatible with high and low speeds)

• USB hub

Compliant to USB Protocol Revision 1.0

Five downstream port channels (One of these channels is dedicated to a function.)

Automatically responds to all USB protocols by hardware.

Descriptor configuration information is provided as ROM data for automatic responding by hardware (vendor

ID and product ID) .

* String data is not supported.

Allows switching between BUS power supply and own power supply modes.

Power supply to the USB down ports is controlled port by port.

• USB function

Compliant to USB Protocol Revision 1.0

Support for full speed

Allows four endpoints to be specified at maximum.

Types of transfer supported : control/interrupt/bulk/isochronous

Built-in DMAC (Maps the buffer for each endpoint on to the internal RAM to directly access the memory for

function’s send and receive data.)

• UART/serial interface

Built-in UART/SIO function (selectable by switching)

• External interrupt

External interrupt (level detection × 8 channels)

Eight inputs are independent of one another and can also be used for resetting from low-power consumption

mode (the L-level detection feature available) .

• Low power consumption (standby mode supported)

Stop mode (There is almost no current consumption since oscillation stops.)

Sleep mode (This mode stops the running CPU.)

• A maximum of 45 general-purpose I/O ports

General-purpose I/O ports (CMOS) : 34

General-purpose output ports (CMOS) : 8

General-purpose I/O ports (Nch open drain) : 3

• Power supply

Supply voltage : 3.0 to 5.5 V
