PIC16LF1716-I/ML Overview
An 8-bit PIC microcontroller (MCU) is a low-cost, low-power RISC processor built on a Harvard architecture with separate program and data buses. PIC MCUs occupy the entry-level and mid-range node in the embedded controller taxonomy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. The PIC16F/LF1716 family sits at the upper end of Microchip's mid-range XLP line, adding on-chip op-amps, 12-bit ADC with computation, 10-bit DAC, Core Independent Peripherals (CLC, COG, NCO, ZCD), and eXtreme Low Power sleep currents below 60 nA typical.
Key features of the PIC16LF1716 include 14KB self-programmable Flash, 1KB RAM, 256 bytes EEPROM, 17-channel 12-bit ADC, two 10-bit DACs, two operational amplifiers, two comparators, four 16-bit timers, one EUSART, two MSSP (I2C/SPI), CLC, COG, NCO, Zero-Cross Detect, and an Integrated Temperature Indicator. The 'LF' prefix denotes the 1.8V-3.6V wide-voltage variant versus the standard 'F' part rated 2.3V-5.5V, making the LF ideal for battery-powered designs that must operate from a depleted Li-coin cell down to 1.8V.
The architecture uses a 14-bit instruction word and 8-bit data path, with a hardware stack and 32-level deep interrupt nesting. The 32 MHz internal oscillator eliminates an external crystal in cost-sensitive designs, while the nanoWatt XLP sleep modes and peripheral module disable logic let active current drop below 30 uA/MHz and sleep current below 60 nA. Intelligent Analog peripherals (op-amps, 12-bit ADC, 10-bit DAC, comparators) are routed through the Peripheral Pin Select (PPS) system for flexible signal conditioning.
Typical applications include IoT sensor nodes, battery-powered thermostats, low-cost sensor conditioning, LED lighting controllers, e-metering, white goods interfaces, wearables, and remote controls. The integrated op-amps and 12-bit ADC make it well suited for direct interfacing with analog sensors (thermistors, photodiodes, strain gauges) without external signal chain components.
When designing with this device, note that the 28-QFN package has an exposed thermal pad that must be soldered to the PCB ground plane for proper electrical and thermal performance. The PPS peripheral mapping allows remapping of digital peripherals to most I/O pins, simplifying PCB layout. Program development uses Microchip's free MPLAB X IDE with XC8 compiler and the MPLAB Code Configurator for peripheral initialization.

Typical Applications
PIC16LF1716-I/ML is suitable for 7 applications: Battery-Powered IoT Sensor Node, Smart Thermostat Control, Industrial Process Sensor Transmitter, Wearable Health Monitoring Band, White Goods LED Display Controller, Electronic Metering / Smart Utility, Consumer Remote Control / HMI.
Battery-Powered IoT Sensor Node
The PIC16LF1716-I/ML fits IoT sensor nodes where 1.8 V-3.6 V operation and nanoWatt XLP sleep current below 60 nA enable multi-year battery life on a CR2032 coin cell. The 14 KB Flash and 1 KB RAM support C-based sensor stacks (LoRaWAN class A, BLE beacon, or Zigbee endpoint), while the integrated 12-bit ADC with 17 channels and two on-chip op-amps directly condition thermistor, photodiode, or strain-gauge outputs without external signal chains. The 32 MHz internal oscillator eliminates an external crystal, shrinking the BOM. With PWM-driven sensor excitation gated on for 100 ms every 30 s, average current stays below 5 uA and battery life exceeds 5 years.

Smart Thermostat Control
In smart thermostat designs the PIC16LF1716-I/ML provides the analog front-end and decision logic for temperature, humidity, and occupancy sensing. The two integrated op-amps buffer thermistor bridges and photo-sensors; the 12-bit ADC with internal reference reads temperature to within 0.1 C accuracy after calibration. Four 16-bit timers drive TRIAC phase-angle control for HVAC loads, and the EUSART plus MSSP connect to a Wi-Fi or BLE co-processor. XLP nanoWatt sleep keeps idle power below 0.5 mW to meet ENERGY STAR standby budgets. The 28-QFN 6x6 mm footprint fits behind the wall-plate PCB.
Recommended
Industrial Process Sensor Transmitter
Industrial 4-20 mA loop-powered transmitters benefit from the PIC16LF1716-I/ML's 1.8 V minimum supply and integrated sensor conditioning. The on-chip op-amps drive a low-side current loop while the 12-bit ADC reads the pressure or load sensor. Industrial -40C to +85C rating and wide 1.8 V-3.6 V supply tolerate the cold-start and brownout conditions of a 4-20 mA loop. The EUSART with RS-485 capability enables HART or Modbus RTU over the same loop interface. Housed in a 28-QFN, the MCU fits 12 mm diameter probe housings used in field instruments.
Recommended
Wearable Health Monitoring Band
Wearable fitness and medical bands use the PIC16LF1716-I/ML for low-power heart-rate, SpO2, and motion processing. The on-chip 12-bit ADC and op-amps interface directly with photoplethysmography (PPG) photodiode front-ends; the two DACs bias the LED drivers. CLC and NCO peripherals generate precision PWM for LED intensity control without CPU overhead. With nanoWatt XLP sleep currents below 60 nA and active current ~188 uA/MHz, the MCU delivers 7-day battery life on a 100 mAh Li-Po cell. The 28-QFN 6x6 mm fits the wristband PCB.
Recommended
White Goods LED Display Controller
White goods washing machines, refrigerators, and dishwashers use the PIC16LF1716-I/ML to drive segmented or dot-matrix LED displays and read user inputs. The PIC16LF1716's 25 I/O pins connect to triac-controlled motor drivers, LED segment drivers, and capacitive touch electrodes. The COG (Complementary Output Generator) peripheral generates dead-time-corrected complementary PWM outputs for induction cooktop power stages, while CLC implements capacitive touch detection without CPU wakeup. Industrial temperature grade and 5V-tolerant I/O (when paired with the PIC16F1716 variant) suit kitchen appliance environments.
Recommended
Electronic Metering / Smart Utility
Electronic water, gas, and heat meters use the PIC16LF1716-I/ML to count pulses from flow sensors and drive LCD or LED displays. The 32 MHz internal oscillator provides the resolution needed for low-flow metering, while the 12-bit ADC reads analog flow or pressure sensor outputs. The CLC peripheral implements pulse counting and tamper detection without CPU intervention, and the EUSART supports wireless M-Bus or LoRaWAN module connections. With nanoWatt XLP sleep below 60 nA, the meter operates for 10+ years on a single lithium battery. The 28-QFN footprint fits inside standard residential meter housings.
Recommended
Consumer Remote Control / HMI
Universal remote controls and small HMI panels use the PIC16LF1716-I/ML for low-cost IR, RF, or capacitive-touch user interfaces. The ADC reads battery voltage for low-battery detection while consuming less than 1 uA in idle mode. The MSSP peripherals drive SPI flash for IR code libraries, and the EUSART drives sub-GHz RF transceivers. Core Independent Peripherals (CLC, NCO) handle capacitive-touch scanning and IR protocol generation in hardware, freeing the CPU to enter XLP sleep between button events. The 28-QFN fits inside a slim CR2032-powered remote housing.

Key Differentiators
- XLP nanoWatt sleep current below 60 nA typical at 1.8 V (vs PIC16LF1619-I/ML)
- Integrated Intelligent Analog (2 op-amps + 2 DACs + 12-bit ADC) (vs PIC16LF1713T-I/MV)
- 28-QFN 6x6 mm with 25 I/O pins for compact designs (vs PIC16LF1559T-I/ML)
- 1.8 V minimum VDD for depleted Li-coin cell operation (vs PIC16F1716-I/ML)
Design Notes
The 28-QFN (6x6) package has an exposed thermal pad that MUST be soldered to the PCB ground plane for proper electrical performance and thermal dissipation. Use an array of thermal vias (8 to 16 vias, 0.3 mm drill) under the pad connecting to the inner ground plane. Decouple VDD (pin 7) with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin, plus a 10 uF bulk capacitor at the board supply input. Pin 4 (VCAP) requires a 1 uF to 10 uF low-ESR ceramic capacitor for the internal voltage regulator.
MCLR pin (pin 24, RE3/MCLR/VPP) can be configured as input-only I/O when MCLR is disabled in configuration bits. If your design does not use external reset, tie MCLR to VDD through a 10 kohm pull-up and a 100 nF decoupling capacitor. A floating MCLR will cause intermittent reset and erratic behavior. When using ICSP, the MCLR/VPP line is driven to ~8.5 V during programming; ensure external circuitry does not sink more than 5 mA from this pin during programming.
Estimated: at 32 MHz and VDD = 3.3 V, active current is approximately 6 mA (188 uA/MHz). For battery-life calculation, the dominant power-down mode is sleep with WDT disabled and all peripherals off, which gives ~60 nA typical. Peripheral module disable (PMD) registers can further reduce active current by 1-2 mA when unused peripherals are disabled. The ADC and op-amps each draw approximately 250-500 uA when active and should be turned off between conversions in duty-cycled sensor applications.
The PIC16LF1716 I/O pins have limited source/sink current (~25 mA per pin, 200 mA total package) and 3.6 V maximum VDD. For driving LEDs or relays, use external MOSFET drivers rather than direct GPIO drive. The 12-bit ADC requires a low-impedance input source (<10 kohm) for accurate conversions above 200 ksps; add an external op-amp buffer if the source impedance exceeds this limit. The MSSP I2C pins (RC3/RC4) require 4.7 kohm pull-ups to VDD for 100 kHz and 2.2 kohm for 400 kHz operation.
