PIC16F726-I/SO Description

The PIC16F726-I/SO is an 8-bit, fully-static Microcontroller unit with a small price tag and low power consumption. It uses CMOS Flash technology and has 28 pins, 22 of which can be used as input/output connections. Oscillator Start-up Timer (OST) and Power-up Timer (PWRT) are included.

In the Energy settings menu, you can activate the SLEEP function. PIC16F72 also has code protection and watchdog timer mode, which help ensure the chip’s consistent performance. Furthermore, this microcontroller module can drastically cut the overall system cost.

It can function on a voltage spectrum from 2V to 5.5V. It is, therefore, suitable for both 3.3V and 5.0V logic-level applications. Core based in the middle, with 35 Instructions and 8 Stack Levels.

  • Programming with ICSPTM (In-Circuit Serial Programming) chips.
  • A capacitive sensing module (touch) has been integrated into the design.
  • “F” Variant, Wide-Ranging Operation Voltage (1.8V – 5.5V).
  • Extremely Low-Power (XLP) “LF” Version (1.8V – 3.6V).


Noise is filtered out of the MCLR Reset route of the PIC16(L)F722/3/4/6/7. When a little pulse is detected, the filter will disregard it. It’s essential to remember that the MCLR pin is not driven low during a Reset. In addition to triggering MCLR Resets, applying voltages to the pin that are too high can cause currents that are too high for the device to handle during an ESD event. Given this, Microchip suggests that the MCLR pin is disconnected from VDD.

● Power-up Timer (PWRT)

The Power-up Timer has a fixed time-out of 64 milliseconds (nominal), and the only time it takes effect is during power-on following a POR or Brown-out Reset. The WDT oscillator is the component that makes it possible for the Power-up Timer to perform its intended function.

● Brown-Out Reset (BOR)

If the BOREN bits in the Configuration register are set, the device will respond to brownouts with a reset. The BORV bit in the Configuration register lets you choose between two different brownout trip points. The voltage range for execution protection can be implemented entirely with the help of the POR and the BOR.

● Time-out Sequence

On power-up, the time-out sequence is as follows: first, PWRT time-out is invoked after POR has expired, then OST is activated after the PWRT time-out has expired. The total time out will vary based on oscillator configuration and PWRTE bit status.

● Power Control (PCON) Register

Both status bits in the Power Control (PCON) register can be used to determine the kind of Reset executed most recently. But 0 is BOR (Brown-out Reset). On Power-on Reset, BOR cannot be determined. After that, the user is the one who is responsible for setting it, and subsequent Resets must check to see if BOR = 0, which would indicate that a brownout has taken place. If the brownout circuit is turned off (BOREN = 00 in the Configuration Word register), the BOR Status bit is set to a “don’t care” value, which means that its behavior is not guaranteed to be predictable.


The family of PIC16(L)F722/3/4/6/7 devices has an interruptible core, which enables specific events to preempt the normal execution of a program. It is the job of an Interrupt Service Routine, often known as an ISR, to identify the cause of the interruption and take the appropriate action. Several interruptions can rouse the MCU from its Sleep mode state.

Low Dropout (LDO) Voltage Regulator

There is a difference between the PIC16F722/3/4/6/7 devices and the PIC16LF722/3/4/6/7 devices because the PIC16F722/3/4/6/7 devices contain an internal Low Dropout (LDO) voltage regulator. The devices with the part numbers PIC16F722/3/4/6/7 have an internal LDO, whereas the ones with the part number PIC16LF722/3/4/6/7 do not. The lithography of the die makes it possible for the internal digital circuitry to function at a maximum operating voltage of 3.6V. To maintain support for designs operating at 5.0V, a low-dropout (LDO) voltage regulator has been integrated onto the die. In spite of the fact that the I/Os operate at 5.0V, the LDO voltage regulator makes it possible for the internal digital logic to function at 3.2V.

In order to guarantee consistent output voltage, the LDO voltage regulator must be equipped with an external bypass capacitor. The external bypass capacitor can be configured to use any one of three pins, one of which is designated as VCAP. It is strongly suggested that the capacitor be a ceramic cap with a value ranging from 0.1 to 1.0 F. It is not the purpose of the VCAP pin to supply power to external loads. An external voltage regulator should be utilized if this functionality is required. In addition, external devices are not recommended to supply power to the VCAP pin. When the device is powered on, the LDO voltage regulator will perceive the external capacitor as a significant load. The device is held in Reset to prevent erroneous operation while a constant current source charges the external capacitor. The device will no longer be in Reset mode once the cap has been charged to its maximum capacity.

I/O Ports

There might be as many as 35 input and output pins used daily. Depending on which peripherals are activated, some pins are unavailable for use as general-purpose I/O. When a peripheral is enabled, the associated pin cannot be utilized as a general-purpose input or output pin. This is the case in most cases.
