Description
OSC1/CLKIN 16 18 I ST/CMOS Oscillator crystal input/external clock source input.
OSC2/CLKOUT 15 17 O — Oscillator crystal output. Connects to crystal or resonator
in crystal oscillator mode. In RC mode, OSC2 pin outputs
CLKOUT which has 1/4 the frequency of OSC1, and
denotes the instruction cycle rate.
MCLR
/VPP
4 4 I/P ST Master clear (reset) input/programming voltage input.
This pin is an active low reset to the device.
PORTA is a bi-directional I/O port.
RA0/AN0 17 19 I/O ST Analog comparator input
RA1/AN1 18 20 I/O ST Analog comparator input
RA2/AN2/V
REF 1 1 I/O ST Analog comparator input or VREF output
RA3/AN3 2 2 I/O ST Analog comparator input /output
RA4/T0CKI 3 3 I/O ST Can be selected to be the clock input to the Timer0
timer/counter or a comparator output. Output is open
drain type.
PORTB is a bi-directional I/O port. PORTB can be
software programmed for internal weak pull-up on all
inputs.
RB0/INT 6 7 I/O
TTL/ST
(1)
RB0/INT can also be selected as an external
interrupt pin.
RB1 7 8 I/O TTL
RB2 8 9 I/O TTL
RB3 9 10 I/O TTL
RB4 10 11 I/O TTL Interrupt on change pin.
RB5 11 12 I/O TTL Interrupt on change pin.
RB6 12 13 I/O TTL/ST
(2)
Interrupt on change pin. Serial programming clock.
RB7 13 14 I/O TTL/ST
(2)
Interrupt on change pin. Serial programming data.
V
SS 5 5,6 P — Ground reference for logic and I/O pins.
V
DD 14 15,16 P — Positive supply for logic and I/O pins.
Legend: O = output I/O = input/output P = power
— = Not used I = Input ST = Schmitt Trigger input
TTL = TTL input
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
Note 2: This buffer is a Schmitt Trigger input when used in serial programming mode.
