PIC16LF77-I/PT is a microcontroller from Microchip Technology, supporting mid-range core PIC16 architecture. It can be used in a wide range of embedded system applications such as embedded networking, remote sensing, smart home, robotics, renewable energy and automation.

Application Field

PIC16LF77-I/PT is an A/D converter, which can measure up to 8 channels of analog inputs. For the digital I/O pins, there are up to 20 ports with each port supporting 8 pins, thus providing 160 general-purpose I/O pins for controlling and monitoring external elements. The latest families are typically equipped with Flash program memory for storing the program for Autonomous operation. The flash memory also allows for bootloader programs, which helps to update the firmware versions quickly and easily, as well as supporting additional external memory of up to 8kB, allowing developers to store code or data externally.

PIC16LF77-I/PT offers great flexibility when used in motor control applications. The low cost of the microcontroller and its small size make it ideal in applications such as motor speed control and motor position control. In addition, the fast execution and control offers smooth dynamic changes in large or small motor drives. Its large capacity of data RAM and scratchpad RAM also offers plenty of operational space for developers to process data quickly and easily.

Besides motor control, PIC16LF77-I/PT is also widely used in Robotics Control and Real Time Control (RTC) applications. Its integrated peripherals offer the support for position encoders and motion sensing, making it an ideal choice for robotics design. Additionally, PIC16LF77-I/PT also supports Pulse-Width Modulation (PWM) signal output and signal capture, which provides great flexibility for driving various types of servo motors.

Working Principle

PIC16LF77-I/PT is a general purpose computer platform, which can be programmed to give desired output or desired intended action/operation after program execution. It works as a mill that can be driven down or up. All the programming is written in the self-contained program memory of the microcontroller, and a running program can be changed within a matter of seconds with a new program. This makes the microcontroller “intelligent”, in that each program is tailor-made to the specific task or application that its user requires. This intelligence enables the running program to make decisions based on input from digital and analog hardware devices, and endow it with the ability to process multi-level commands and complex tasks.

At its heart, PIC16LF77-I/PT is an 8-bit RISC processor. This means that the processor is capable of running 8-bit instructions. Although the processor is limited in this respect, most embedded applications do not require a 32-bit processor, as the 8-bit processor is quite capable of handling the task at hand. Furthermore, this processor is based on Harvard architecture, which allows the program data to be stored in two different memories. This allows multi-tasking to be performed, as the microcontroller can be executing one program while another is being loaded into memory, ready to run once the processor is ready.

The peripherals onboard PIC16LF77-I/PT can also be programmed to perform some basic controls on the system. It may be used to control a motor, to read a sensor and to operate an LED light. For example, the PWM port can be used to control the motor’s speed, while a single-channel analog-to-digital converter can be used to take measure of sensor values. The I/O port may be programmed to act as an LED light, which can be used to signal the working state of the microcontroller.

In summary, PIC16LF77-I/PT is a powerful and flexible microcontroller, which is well suited for different embedded system applications. It is programmed using a high-level language such as C and its program memory allows for quick and easy updating of the firmware. Its integrated peripherals, such as PWM, A/D converter, timer/counter and I/O port, are very useful when it comes to controlling or monitoring external elements. All these factors renders it an ideal choice for motor control, robotics, as well as remote sensing applications.
