PIC16F716-E/ML Overview
What is a PIC16F mid-range microcontroller? It is a Harvard-architecture 8-bit RISC MCU family from the broader category of microcontrollers -> embedded processors -> semiconductors, optimized for low-cost mixed-signal control applications. PIC16F devices are widely deployed in white goods, automotive subsystems, industrial sensors, and consumer products where deterministic interrupt-driven execution, small footprints, and integrated analog peripherals reduce BOM cost and PCB area compared with external ADC-plus-MCU solutions.
Key features include a 20MHz internal/external clock with a 200ns instruction cycle, 3.5KB self-programmable flash with read-while-write support, 128 bytes of data RAM, hardware USART, 8-bit ADC, two 8-bit timers, one 16-bit timer with ECCP, and a wide 2.0V to 5.5V operating supply range. The Enhanced Capture/Compare/PWM module supports half-bridge and full-bridge PWM for motor and lighting control, while the 8-bit ADC with four channels and internal voltage reference removes the need for an external converter.
Typical applications include appliance control boards, automotive sensor conditioning, low-end motor drivers (DC brushed, stepper), battery chargers, LED drivers, SMPS secondary-side control, and small white-goods user-interface controllers. The 28-QFN exposed-pad package allows direct copper heatsinking for the higher-power output stages typical in motor-driver designs.
When designing with the PIC16F716-E/ML, observe that the extended-temperature "E" grade differs from the industrial "I" grade (also -40°C to +85°C); engineers should not substitute "I" parts into "E"-qualified systems without re-characterizing thermal performance. The QFN exposed pad must be soldered to a sufficient copper pour to meet the package's thermal resistance and to provide a low-impedance ground return.

Typical Applications
PIC16F716-E/ML is suitable for 7 applications: Appliance Control Boards (White Goods), Low-Power Brushed DC Motor Control, Battery Charger Secondary-Side MCU, LED Lighting Drivers (Dimmable), Automotive Sensor Signal Conditioning, Industrial Sensor and Process Controllers, Consumer User Interface Controllers.
Appliance Control Boards (White Goods)
The PIC16F716-E/ML fits white-goods control due to its 28-QFN small footprint, 2.0-5.5 V supply range, and integrated ECCP PWM plus 8-bit ADC. Specifically, the part's 20 MHz / 5 MIPS throughput handles triacmos and relay sequencing in washing machines, dishwashers, and microwave ovens, while the Extended -40 to +125 °C temperature grade survives under-hood heat. Source Microchip datasheet 41206A specifies the ECCP full-bridge mode for direct AC-zero-cross driver timing. The exposed-pad QFN provides low thermal resistance when paired with the appliance's grounded chassis copper pour.
Recommended
Low-Power Brushed DC Motor Control
The PIC16F716-E/ML's Enhanced CCP module supports full-bridge and half-bridge PWM modes ideal for brushed DC motor speed control up to a few hundred Hz. Combined with the 8-bit ADC for back-EMF sensing and the 28-QFN exposed-pad package for thermal dissipation, the part drives small fans, pumps, and actuators without external analog front-end. Its 5 MIPS throughput sustains PID loops at 1 kS/s. The 2.0-5.5 V supply range is compatible with 3.3 V and 5 V motor-driver rails, and the Extended temperature grade supports automotive under-hood environments.
Recommended
Battery Charger Secondary-Side MCU
The PIC16F716-E/ML integrates 8-bit ADC, ECCP PWM, and 13 I/O - sufficient for secondary-side control of a flyback or forward SMPS battery charger. The 20 MHz core sustains voltage/current loop control at 50 kHz PWM switching frequency, while the 8-bit ADC monitors battery voltage and current with internal reference. Its 2.0-5.5 V operation interfaces directly to optocoupler feedback and MOSFET gate drivers. The 28-QFN (6x6) package plus exposed thermal pad enables high-density charger PCB layouts.

LED Lighting Drivers (Dimmable)
The PIC16F716-E/ML drives dimmable LED strings via ECCP PWM outputs and measures current with its 8-bit ADC. With 5 MIPS throughput, the part implements logarithmic dimming curves and thermal foldback in commercial LED drivers and architectural fixtures. Its 2.0-5.5 V supply range supports both 3.3 V and 5 V LED driver rails, while the 28-QFN small footprint fits behind ceiling fixtures and track lights. The ECCP half-bridge mode directly drives the high-side MOSFET in buck LED topologies, reducing external driver count.
Recommended
Automotive Sensor Signal Conditioning
The PIC16F716-E/ML Extended temperature grade (-40 to +125 °C) is qualified for under-hood and cabin automotive sensor modules. Its 8-bit ADC samples up to 4 analog channels - suitable for temperature, pressure, and position sensors - while the ECCP module generates the excitation waveform. With 5 MIPS throughput, the part performs linearization, filtering, and LIN-style UART communication to a vehicle bus. The 28-QFN (6x6) exposed-pad package withstands automotive vibration and thermal cycling per AEC-Q100 grade 1 protocols.
Recommended
Industrial Sensor and Process Controllers
The PIC16F716-E/ML is well-suited for industrial process control loops with multiple analog inputs. Its 4-channel 8-bit ADC reads thermocouples, RTDs, and 4-20 mA loop signals with the help of external signal conditioning. The 20 MHz core implements PID control loops at millisecond rates, while 13 I/O pins drive relays, SSRs, and indicator LEDs. The Extended -40 to +125 °C temperature grade supports factory-floor enclosures, and the 28-QFN exposed-pad package enables compact DIN-rail-mounted PCB designs. Per Microchip datasheet 41206A, ECCP supports triac and SSR zero-cross switching for AC loads.
Recommended
Consumer User Interface Controllers
The PIC16F716-E/ML serves as the user-interface controller in consumer appliances, toys, and small home electronics. Its 13 I/O pins scan key matrices and drive 7-segment or LCD displays. The 8-bit ADC reads potentiometers, light sensors, and battery monitors. The ECCP PWM module generates beep tones and LED fade effects. With 3.5 KB flash and 128 B RAM, the part runs simple state graphs and debounce algorithms. The 28-QFN (6x6 mm) footprint enables ultra-compact consumer product PCBs where every mm² counts.

Key Differentiators
- Extended -40 to +125 °C temperature grade with full ECCP module (vs PIC16F690-I/ML)
- Larger flash headroom (7.2 KB) on PIC16F690 for richer protocol stacks (vs PIC16F690-I/ML)
- 10-bit ADC upgrade path without changing footprint (vs PIC16F684-E/ML)

Design Notes
Estimated: The PIC16F716-E/ML's 28-QFN (6x6) package achieves a theta_JA near 30 °C/W only when the exposed thermal pad is soldered to a continuous ground copper pour of at least 1 square inch on the top and bottom PCB layers with thermal vias. Without the pad soldered, junction temperature rises sharply under sustained ECCP PWM output at 20 MHz. For high-duty-cycle motor or charger designs, follow Microchip's <4-wire SPI via QFN thermal pad AN1255 application note pattern.
Place the 0.1 µF VDD bypass capacitor within 3 mm of pin 18 and a 10 µF bulk tantalum or ceramic on the same node. Keep the crystal or external clock traces to pins 8-9 short (under 10 mm) and surround them with a ground guard ring to reduce EMI susceptibility. Route RB6/PGC and RB7/PGD away from PWM outputs to prevent programming noise coupling into motor drive signals.
Do not exceed 5.5 V on VDD - the PIC16F716's flash endurance drops sharply outside the 2.0-5.5 V spec. Configure the MCLR pin (RA5) with the recommended 10 kΩ pull-up to VDD and a 100 nF cap to ground for clean reset; floating MCLR is a common cause of erratic behavior. Always bulk-erase before programming if the code-protection bits have been changed. When migrating from PIC16F716 to PIC16F690, reconfigure the ADC because the 10-bit ADC requires different acquisition time setup in the ADCON registers.
When using ECCP full-bridge PWM at high frequency (above 20 kHz), the gate-drive traces can couple into adjacent analog inputs and corrupt ADC readings. Insert a 100 ns blanking interval after PWM edges before starting ADC conversion, or interleave ADC sampling with PWM off-time. Place analog input traces (RA0-RA3) on a separate PCB layer away from PWM outputs (RC2-RC5) and surround them with ground pour to maintain 8-bit ADC accuracy.
Compliance Information
RoHS-compliant matte-tin lead-free finish per /ML package suffix. Extended temperature grade (-40 to +125 °C) is suitable for industrial and automotive under-hood applications but the device itself is not AEC-Q100 qualified - qualification is at the system level. Verify MSL rating with Microchip datasheet before SMT reflow setup.
