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
→12 MHz internal system clock)
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 full 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) .
Note: 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 V to 5.5 V
