Timer

 16-bit timer:

8 channels

 12-bit interval timer: 1 channel

 Watchdog timer:

1 channel (operable with the

dedicated low-speed on-chip

oscillator)

 Real-time clock 2:

1 channel (99-year calendar,

alarm function, and clock

correction function)

A/D converter

 8/10-bit resolution A/D converter (VDD = 2.4 to 5.5 V)

 Analog input: 4 to 11 channels

 Internal reference voltage (0.815 V (TYP.)),

temperature sensor, and touch TSCAP voltage

selection

Comparator

 1 to 2 channels

 Operation mode: High-speed mode, low-speed mode

 External reference voltage or internal reference

voltage can be selected as the reference voltage.

Capacitive touch sensing unit (CTSUb)

 15 channels

 Self-capacitance method: A single pin configures a

single key, supporting up to 15 keys

 Mutual capacitance method: A key can be created

with a matrix configuration by selecting

transmit/receive pins from 15 pins. Up to 16 keys are

supported.

I/O port

 I/O port: 8 to 30 (N-ch open drain I/O [withstand

voltage of 6 V]: 0 to 2)

 Can be set to N-ch open drain and on-chip pull-up

resistor

 External interrupt function: 10 channels

 On-chip clock output/buzzer output controller

Others

 On-chip BCD (binary-coded decimal) correction

circuit

Remark

The functions mounted depend on the

product. See 1.6 Outline of Functions.
