Microcontrollers are electronic devices on a single integrated circuit chip, normally containing the processor and peripheral devices like timers and communication interfaces. PIC16LF720-E/P is a mid-range class microcontroller with 8 bits Central Processing Unit (CPU) and it belongs to the 14-bit family of the PIC products. This chip has several programmable operating modes that provide flexibility such as, low voltage detect (LVD), power saving sleep modes, and watchdog timer (WDT).

Application Field

PIC16LF720-E/P is widely used in industrial and commercial applications. This chip is mostly used to develop small low-power applications, since its features include a wide operating temperature range and low power consumption. In addition, it is suitable for designing embedded control systems for industrial automation, automotive control, robotics, building and home automation, medical, office and home equipment.

Moreover, this chip is used in motor control applications such as speed and torque regulation. Also, due to its low power consumption, it is suitable for applications that require long battery life; for example, portable medical instruments. Furthermore, due to its fast processing capability, PIC16LF720-E/P can be used for high data rate applications such as ethernet, cellular and WiFi.

Working Principle

PIC16LF720-E/P features several peripherals such as up to 4 Analog to Digital Conversion (ADC), 3 Timer Capture Input (TCI) and 3 Timer Compare Output (TCO). These peripherals are the main components of the device which enable it to perform functions according to user specifications. The pulse width modulation (PWM) features enable controlling motors, lights, sounds and vibration of a system. Additionally, the integrated input capture (IC) unit provides the ability to detect and measure pulse rate and width.

The hardware PWM feature of the chip utilizes the on-chip oscillator which is used to generate the PWM signals. The oscillator runs at a fixed frequency which is then divided down to obtain the required PWM frequency. Then, by varying the duty cycle of the output signals, specific PWM outputs can be achieved. Another key feature of this microcontroller is the sleep mode which allows the device to enter into low power consumption state when idle for extended periods.

The on-chip watchdog timer (WDT) is another feature used by PIC16LF720-E/P. WDT activates whenever the device is in an idle state and is responsible for resetting the system in case of malfunction. This timer can be used to ensure the system will recover from a fault. Additionally, the timer can be used to detect system lock-ups, enabling users to provide an error: handler routine in case of failure. The data EEPROM used in this microcontroller can store constants, adjustment values and other parameters.

Conclusion

PIC16LF720E/P is a mid-range microcontroller with 8 bits Central Processing Unit and it belongs to the 14-bit family of the PIC products. This chip can be used for a wide range of applications from industrial automation and automotive control to motor control and home automation. This microcontroller has several features such as low voltage detect (LVD), power saving sleep modes, watchdog timer (WDT), pulse width modulation (PMW) and data EEPROM.

In conclusion, the PIC16LF720-E/P is a flexible, low power consumption microcontroller suitable for a variety of application fields. Its various features and operating modes provide design-efficient solutions for a great number of applications.
