How many ports does PIC 18 have?
– A PIC18 may have as many as 10 I/O ports. – An I/O port is often multiplexed with one or more peripheral functions. – When a peripheral function is enabled, the I/O pins cannot be used for general- purpose I/O. – Devices with 18 pins and 20 pins have two I/O ports: A and B.
How many ports are available for PIC18F458?
Number of Individual Port Pins For example, for the PIC18F458, Port A has 7 pins; Ports B, C, and D each have 8 pins; and Port E has only 3 pins. Each port has three SFRs associated with it. — PORTx, TRISx (TRIState), and LATx (LATch).
How many ports are available in PIC18F4520 microcontroller?
The PIC18F4520 has digital I/O pins organized into five ports. Ports A-D consist of eight pins each, while Port E has only three, although some of these pins are primarily used for communication. The diagram below shows the layout of the different ports on the PIC18F4520 microcontroller.

How many ports does 18f4580 Picture?
PIC18F4580 Mini Development Board has 3 SMD LEDs connected to port pins RB1, RB2 and RB3 via jumpers J1, J2 and J10 respectively. If any jumper is left open, then the corresponding port pin can be used independently. The sample code given below toggles the LEDs in fixed intervals.
How many ports are there in microcontroller?
8051 microcontrollers have 4 I/O ports each of 8-bit, which can be configured as input or output. Hence, total 32 input/output pins allow the microcontroller to be connected with the peripheral devices.
What are ports in microcontrollers?
Ports are represented by registers inside the microcontroller, and allow the program (firmware) to control the state of the pins, or conversely, read the state of the pins if they are configured as inputs. There is a one-to-one correspondence between the pins on the microcontroller and the bits in its registers.
What is IO port in microcontroller?
8051 microcontrollers have 4 I/O ports each of 8-bit, which can be configured as input or output. Hence, total 32 input/output pins allow the microcontroller to be connected with the peripheral devices. Pin configuration, i.e. the pin can be configured as 1 for input and 0 for output as per the logic state.
How many ports does pic18f 4550 have?
PIC18F4550 Ports PIC16F877a has 5 Ports in total which are: Port A: It has 6 Pins in total starting from Pin # 2 to Pin # 7.
What is port in PIC microcontroller?
IT has 5 Ports in total. ( PortA, PortB, PortC, PortD and PortE). It supports Serial Communication for which it has 2 Pins TX and RX. You can receive data from RX and can transmit data from TX.
What is port C in a microcontroller?
PORTC is composed of pin labelled RC0 to RC7. PORTD is composed of pins labelled RD0 to RD7. PORTE is composed of pins labelled RE0 to RE3. When running a program on a microcontroller that uses inputs and outputs, the port(s) being used must be set in code.
