PIC16F505 PINOUT DESCRIPTION
Name
Function
Input
Type
Output
Type
Description
RB0/ICSPDAT
RB0
TTL
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
ICSPDAT
ST
CMOS In-Circuit Serial Programming data pin.
RB1/ICSPCLK
RB1
TTL
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
ICSPCLK
ST
CMOS In-Circuit Serial Programming clock pin.
RB2
TTL
CMOS Bidirectional I/O pin.
RB3/MCLR/VPP
RB3
TTL
Input port. Can be software programmed for internal weak
pull-up and wake-up from Sleep on pin change.
MCLR
ST
Master Clear (Reset). When configured as MCLR, this pin is
an active-low Reset to the device. Voltage on MCLR/VPP must
not exceed VDD during normal device operation or the device
will enter Programming mode. Weak pull-up always on if
configured as MCLR.
VPP
HV
Programming voltage input.
RB4/OSC2/CLKOUT
RB4
TTL
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
OSC2
XTAL
Oscillator crystal output. Connections to crystal or resonator in
Crystal Oscillator mode (XT, HS and LP modes only).
CLKOUT
CMOS In EXTRC and INTRC modes, the pin output can be
configured for CLKOUT, which has 1/4 the frequency of OSC1
and denotes the instruction cycle rate.
RB5/OSC1/CLKIN
RB5
TTL
CMOS Bidirectional I/O pin.
OSC1
XTAL
Crystal input.
CLKIN
ST
External clock source input.
RC0
TTL
CMOS Bidirectional I/O pin.
RC1
TTL
CMOS Bidirectional I/O pin.
RC2
TTL
CMOS Bidirectional I/O pin.
RC3
TTL
CMOS Bidirectional I/O pin.
RC4
TTL
CMOS Bidirectional I/O pin.
RC5/T0CKI
RC5
TTL
CMOS Bidirectional I/O pin.
T0CKI
ST
Clock input to TMR0.
VDD
P
Positive supply for logic and I/O pins.
VSS
P
Ground reference for logic and I/O pins.
Legend: I = Input, O = Output, I/O = Input/Output, P = Power, — = Not used, TTL = TTL input,
ST = Schmitt Trigger input, HV = High Voltage
