PIN NAME
TYPE
DESCRIPTION
P0 [1:0] / INT [1:0]
I
P0 [1:0]: Input only pin/ wakeup/pull-up/Schmitt trigger input
INT [1:0]: External interrupt
P0 .2
I
P0.2: Input only pin/wake up/pull-up/Schmitt trigger input
P2 [7:0]
I/O
P2 [7:0] bi-direction pins/pull-up/Schmitt trigger input
P4 [7:0] / AIN [7:0]
I/O
Bi-direction pins/pull-up /ADC input/
without
Schmitt trigger input
P5 [5:0]
I/O
Bi-direction pins/pull-up/Schmitt trigger input
P5.4: PWM0/BZ0, P5.3: PWM1/BZ1
AVREFH
I
ADC highest reference voltage input
(NOTE
:
The ADC reference voltage (AVREFH) of SN8P27142 and SN8P27143 are
VDD.)
DAO
O
Current type DAC output
P0.3/RST/VPP I/P
P0.3:
Schmitt trigger input pin /
NO pull-up,
NO wakeup
/ in RC mode
P0.3 is input only pin without pull-up resistor under P0.3 mode. Add the 100 ohm
external resistor on P0.3, when it is set to be input pin.
RST: External reset, active “low”
VPP: OTP programming pin
XIN
I
External oscillator input pin. / External RC oscillator input
XOUT/P5.6
I/O
XOUT: External oscillator output pin.
P5.6: Bi-direction pin/pull-up/Schmitt trigger input in RC mode
VDD, VSS
P
Power supply pins.
