FUNCTION
IC reset input, low active.
32 KHz crystal oscillator with divider for time-keeping application
32 KHz crystal oscillator with divider for time-keeping application
Main-clock oscillation input. Only Ring type is used. Connect to GND via the
oscillation resistor.
General input port with pull-high selection. Each 2 input pins can be
programmed to generate interrupt request and used to release IC from
STOP mode.
IP0[3:0] are used as the input of ADC. IP0.0 is the input pin of channel 0
and IP0.3 is the input pin of channel 3, and so on.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type and it can sink 8mA for high-current applications. When
used as input pin, there may have a pull-high option and generate interrupt
request to release IC from STOP mode.
When BP0[7] is used as output pin, it can be the IR transmission carrier for
IR applications.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type. When used as input pin, there may have a pull-high option
and generate interrupt request to release IC from STOP mode.
When serial interface is enabled, BP1[6:4] are used as serial interface pins.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type. When used as input pin, there may have a pull-high option
and generate interrupt request to release IC from STOP mode.
Reference-bottom voltage of ADC. Theoretically, the converted codes 0 ~
255 will be uniformly distributed between VRB and AVDD. Voltages below
VRB will be mapped to code 0.
Capacitor input for ADC.
Capacitor output for ADC.
ADC regulator output voltage.
Current type DAC speaker output 0.
Current type DAC speaker output 1.
Test input, internally pulled low. Do not connect during normal operation.
Positive power supply for µP and peripherals.
Negative power supply for µP and peripherals.
Positive power supply for oscillation.
Negative power supply for oscillation.
Positive power supply for ADC module.
Negative power supply for ADC module.
2 _{Only W567S301~S341 provides these pins for ADC application.}
3 _{In order to get a stable oscillating frequency, W567S080~S341 provides these pins for power supply.}
