Description
PB0/AN0
PB1/AN1
PB2/AN2
PB3/AN3
PB4/AN4
PB5/AN5
PB6/AN6
PB7/AN7
I/O
Pull-high
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mined by pull-high option: port option) or A/D input.
Once a PB line is selected as an A/D input (by using software control), the
I/O function and pull-high resistor are disabled automatically.
PA0~PA2
PA3/PFD
PA4/TMR
PA5/INT
PA6/SDA
PA7/SCL
I/O
Pull-high
Wake-up
PA3 or PFD
I/O or Serial Bus
Bidirectional 8-bit input/output port. Each bit can be configured as wake-up
input by ROM code option. Software instructions determine the CMOS out-
put or Schmitt trigger input with or without pull-high resistor (determined by
pull-high options: bit option). The PFD, TMR and INT are pin-shared with
PA3, PA4 and PA5, respectively. Once the I
2
C BUS function is used, the in-
ternal registers related to PA6 and PA7 can not be used.
VSS
Negative power supply, ground.
PC0~PC4
I/O
Pull-high
Bidirectional 5-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mine by pull-high option: port option).
PD0/PWM0
PD1/PWM1
I/O
Pull-high
I/O or PWM
Bidirectional 2-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without a pull-high resistor (de-
termined by pull-high option: port option). The PWM0/PWM1 output func-
tion are pin-shared with PD0/PD1 (dependent on PWM optios).
RES
I
Schmitt trigger reset input. Active low.
VDD
Positive power supply
OSC1
OSC2
I
O
Crystal
or RC
OSC1, OSC2 are connected to an RC network or a Crystal (determined by
ROM code option) for the internal system clock. In the case of RC opera-
tion, OSC2 is the output terminal for 1/4 system clock.
Absolute Maximum Ratings
Supply Voltage...........................V
SS
0.3V to V
SS
+5.5V
Storage Temperature............................ 50 C to 125 C
Input Voltage..............................V
SS
0.3V to V
DD
+0.3V
Operating Temperature........................... 40 C to 85 C
Note: These are stress ratings only. Stresses exceeding the range specified under Absolute Maximum Ratings may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
