PIC16LF1716-I/MV Обзор
A microcontroller (MCU) is a single-chip processor that combines a CPU, program and data memory, and configurable peripherals on one die, executing firmware instructions in real time. MCUs sit at the bottom of the embedded-processing hierarchy and are differentiated from microprocessors by their integrated peripherals and lower-power sleep modes. Within Microchip's portfolio, PIC16F/LF parts balance 8-bit simplicity with on-chip analog, while PIC18 adds more memory, and dsPIC/PIC32 families move to 16-bit and 32-bit cores respectively. The LF prefix designates the wide-voltage, low-power XLP variant aimed at battery and energy-harvesting applications.
Key features of the PIC16LF1716-I/MV include eXtreme Low Power (XLP) technology with deep sleep currents in the nanoampere range, peripheral pin select (PPS) for flexible signal routing, and up to 25 mA per I/O source/sink capable of directly driving LEDs. The 32 MHz maximum clock delivers 8 MIPS throughput, while 256 bytes of EEPROM and 1024 bytes of RAM support small data buffers with byte-level endurance.
Typical applications span sensor signal conditioning with on-chip op-amps, low-power battery-powered IoT nodes, LED driving with PWM, brushless-DC commutation using COG, and industrial control loops using comparators and ADC feedback. The QFN-28 footprint simplifies layout on densely populated mixed-signal boards.
Designers should note that VDD must be decoupled with a 100 nF ceramic capacitor within 1-2 mm of the package pin and that the exposed thermal pad must be soldered to a copper pour for proper heat dissipation. Programming is via ICSP on PGC/PGD pins shared with RB6/RB7, requiring isolation resistors if these pins are used in the application.

Типичное применение
PIC16LF1716-I/MV подходит для 6 применениеs: Battery-Powered IoT Sensor Node, Precision Analog Front-End Conditioning, LED Lighting and PWM Driver Control, Industrial Process Control Loops, Brushless DC Motor Commutation, Consumer Appliance User Interface.
Battery-Powered IoT Sensor Node
The PIC16LF1716-I/MV fits battery-powered IoT sensor nodes where the 1.8V-3.6V XLP supply range and nanoamp sleep current keep coin-cell or 2xAA battery life measured in years. Its 17-channel 10-bit ADC directly digitises multiple sensor inputs while integrated op-amps condition thermocouple, RTD, or bridge signals without external analog ICs - cutting BOM and PCB area. At 32 MHz the MCU delivers 8 MIPS for local data averaging, threshold detection, or simple protocol framing before periodic radio wake-up. PPS routes the ADC triggering, comparator wake events, and PWM outputs efficiently, so sensor sampling and housekeeping share I/O without pin conflicts. Compared to an external-ADC design, the LF1716 achieves similar effective resolution with lower quiescent current and a smaller layout.
Рекомендуется
Precision Analog Front-End Conditioning
The PIC16LF1716-I/MV is well matched to precision analog front-end signal chains thanks to its integrated operational amplifiers, 5-bit and 8-bit DACs for programmable gain/reference generation, and high-speed comparators on-chip. Designers can construct active filters, instrumentation stages, and threshold comparators without external amplifiers - the input impedance and gain bandwidth are sized for kHz sensor-bandwidth applications. The 17-channel ADC samples differential or single-ended signals from strain gauges, photodiodes, or bridge sensors. Using PPS the comparator trigger, COG (Complementary Output Generator), and PWM outputs route to any pin, simplifying PCB routing on mixed-signal boards. Compared to a discrete approach, the LF1716 reduces analog IC count by 2-3 parts while retaining XLP low-power behaviour for portable instruments.
Рекомендуется
LED Lighting and PWM Driver Control
The PIC16LF1716-I/MV drives LED lighting and PWM control via its 25 mA source/sink-capable I/O pins, multiple 10-bit PWM channels, and the on-chip COG (Complementary Output Generator) for synchronous rectified LED or motor half-bridge drive. Designers can use the comparator and op-amp front-end to implement constant-current regulation, programmable brightness curves via the 8-bit DAC, and zero-cross detect for AC-mains dimmer interface logic. The 32 MHz CPU runs timing-critical LED control loops with deterministic latency while power-managed sleep between PWM cycles saves quiescent current. Compared to a discrete PWM generator + LED driver pair, the LF1716 unifies timing, current sensing, and communication (EUSART) for tunable-white or RGBW fixtures in one package.
Рекомендуется
Industrial Process Control Loops
The PIC16LF1716-I/MV fits industrial process control loops with its high-speed comparators for threshold detection, on-chip 10-bit ADC for feedback signal acquisition, and PPS for assigning control outputs to any I/O pin. Its -40C to +85C industrial temperature range, integrated op-amps for current-loop (4-20 mA) signal translation, and on-chip COG simplify closed-loop PID implementation in PLC modules and motor starters. The Core-Independent Peripherals (CLC, NCO, ZCD) implement deterministic state-machine-based control without CPU overhead, freeing CPU cycles for EUSART communication to PLC backplanes. Compared to an external analog controller + DAC + PWM combo, the LF1716 reduces part count and PCB area while retaining robust industrial temperature range compliance.
Рекомендуется
Brushless DC Motor Commutation
The PIC16LF1716-I/MV drives brushless DC motor commutation through its integrated COG (Complementary Output Generator) peripheral that produces hardware-timed complementary PWM signals with programmable dead-band insertion. Hall-sensor or back-EMF zero-cross-detect feedback flows directly into the on-chip comparators and ZCD module, then triggers automatic commutation via CLC state machines - all without CPU intervention for fast zero-crossing response. The 32 MIPS CPU then handles only startup, ramp profiling, and speed-loop updates, freeing execution budget for EUSART or I2C communication with host controllers. Compared to discrete MCU + MOSFET-driver arrangements, the LF1716 unifies analog feedback (op-amp, ZCD) and digital control in one package suited for compact fan, pump, and small-appliance motor designs.
Рекомендуется
Consumer Appliance User Interface
The PIC16LF1716-I/MV suits consumer-appliance user interface modules with on-chip op-amps for keypad/resistive-touch scanning, 17-channel ADC for slider readout, PPS-driven PWM for backlight brightness control, and 25 mA I/O capable of directly driving LED indicators and buzzer transistors. EUSART and I2C peripherals implement communication to the main appliance controller, while XLP deep-sleep currents under 100 nA ensure standby budgets are tiny when the UI is inactive. The integrated DAC can produce a programmable bias voltage for sensor-bias reference circuits. Compared to an external op-amp + PWM-driver approach, the LF1716 replaces 2-3 ICs in a typical white-good user-interface panel.

Заметки по проектированию
Place a 100 nF ceramic decoupling capacitor within 1-2 mm of the VDD pin (pin 8) and a bulk 4.7-10 uF tantalum or ceramic capacitor on the same node. Also decouple AVSS/VDD analog rails separately to keep ADC accuracy. For battery-powered designs, use a low-Iq LDO such as MCP1700 to extend sleep-mode runtime; the LF1716's nanoamp-level sleep currents then dominate the system budget.
Solder the exposed thermal pad (EP) of the 28-UQFN package to a 4 mm x 4 mm copper pour with multiple thermal vias to internal layers. Although 8-bit PIC MCUs dissipate negligible power in active mode, the EP ensures stable thermal behaviour and grounds the analog references. Estimated: with theta_JA around 30 C/W typical for 28-UQFN 4x4 mm, even a worst-case 100 mW dissipation only raises junction ~3 C above ambient - so EP is more about EMC ground than heat.
Route the ICSP pins RB6/PGC and RB7/PGD as short-trace pairs to a 6-pin header with isolation resistors (typically 4.7k-10k ohm in series) if these pins are also used in the application circuit. This lets a PICkit programmer attach without disrupting operation. Keep analog inputs (RA0-RA4, RB0-RB5) away from high-current digital traces; the integrated ADC and op-amps are sensitive to digital noise injected through the package substrate.
Do not exceed 3.6 V on any VDD pin - the LF1716 is permanently damaged above 4.0 V abs-max. Disable unused peripherals via the CMCON, ANSEL, and TRIS registers to achieve the lowest sleep current; a default factory POR state leaves comparators and ADC drawing bias current. When migrating firmware from the LF1713, account for the different pin mapping of ADC channels and comparator inputs despite shared silicon die.
