Table 2-7 Pin Names and Functions (6 of 6)
Pin for supplying a low-frequency oscillator with power: 3 V power supply
Oscillator GND pin (0 V)
Power supply pin: 1.5 V power supply
Power supply pin: 3 V power supply
Power supply pin: GND pin (0 V)
Power supply pin for the D/A converter: 2.5 V power supply
If the D/A converter is not used, connect (fix) this pin to GND.
Reference power supply pin for the D/A converter
If the D/A converter is not used, connect (fix) this pin to GND.
GND pin (0 V) for the D/A converter
Connect this pin to GND even if the D/A converter is not used.
Pin for connecting a stabilizing capacitor to the D/A converter
Pin for connecting a stabilizing capacitor to the D/A converter
D/A converter 0 output pin
D/A converter 1 output pin
Pin for setting a single boot mode: This pin goes into single boot mode by sampling "L" at the
rise of a reset signal. It is used to overwrite internal flash memory. By sampling "H (DVCC3)
level" at the rise of a reset signal, it performs a normal operation. This pin should be pulled up
under normal operating conditions. Pull it up when resetting.
(With pull-up)
Pin (H) for supplying the A/D converter with a reference power supply
Connect this pin to AVCC3 if the A/D converter is not used.
Pin for supplying the A/D converter with a power supply. Connect it to a power supply even if
the A/D converter is not used.
A/D converter GND pin (0 V). Connect this pin to GND even if the A/D converter is not used.
Pin (L) for supplying the A/D converter with a reference power supply
TEST pin: To be fixed to DVCC3 (with Schmitt trigger)
TEST pin: To be fixed to DVCC3
TEST pin: Set to OPEN.
TEST pin: Set to OPEN.
TEST pin: Set to OPEN.
Pin for supplying a high-frequency oscillator with power: 1.5 V power supply
