PIC16F716-I/ML Overview
A PIC16F microcontroller is an 8-bit RISC core built on Microchip's PIC16 Harvard architecture, designed for deterministic real-time control in cost-sensitive embedded systems. The PIC16F family spans LDO-equipped mid-range parts from 14 to 64 pins with on-chip peripherals aimed at motor control, power conversion, lighting, and sensor conditioning. Within that family the PIC16F716 occupies the mid-density niche where 4 ADC channels and ECCP hardware PWM are needed but USB, CAN, or >20 MHz performance are not.
Headline specifications include a 2.0 V to 5.5 V operating range suitable for both 3.3 V and 5 V designs, an enhanced PWM with half-bridge, full-bridge, and programmable dead-band control, a USART/SCI module for asynchronous serial communication, and a 25 mA source/sink capability per I/O pin capable of directly driving LEDs and small MOSFETs. The 28-QFN exposed-pad package delivers a footprint of roughly 6 mm by 6 mm with a thermal pad that must be soldered to a ground copper pour for heat dissipation and electrical reference. The internal oscillator can be software tuned from 31 kHz up to 8 MHz and supports an external clock mode up to 20 MHz via the OSC1/OSC2 pins.
Typical applications span LED lighting drivers, sensor signal conditioning, battery chargers, motor and fan control, small appliance control boards, automotive body (lighting) lighting modules, and industrial metering front-ends. The wide 2 V to 5.5 V supply tolerance allows the device to run directly from a single lithium cell, three alkaline cells, a regulated 3.3 V rail, or a 5 V USB bus without an external supervisor.
A practical design consideration is that the on-chip debug memory is configurable in development mode but must be disabled for production to recover the full program-memory space. The 28-QFN package requires careful PCB layout: a 0.5 mm pitch land pattern with a centered thermal pad, four-via ground array, and post-reflow X-ray verification for hidden solder joints under the thermal pad.

Typical Applications
PIC16F716-I/ML is suitable for 6 applications: LED Lighting Drivers and Dimming Control, Battery-Powered Sensor Conditioning, Small Motor and Fan Control (BLDC / Brushed), Automotive Body Electronics and Lighting, Industrial Metering and Front-End Signal Conditioning, Small Appliance and Consumer Control Boards.
LED Lighting Drivers and Dimming Control
The PIC16F716-I/ML fits LED driver and dimming control boards where its 4 ADC channels sense potentiometer or 0-10 V dim inputs and the Enhanced CCP module produces PWM dimming with programmable dead-band. Its 25 mA I/O source/sink capability can directly switch small MOSFETs and the ECCP half/full-bridge modes can drive HBLED strings in buck, boost, or buck-boost topologies. With 3.5 KB flash and 128 B RAM, the part runs PID-style brightness loops and DMX/0-10 V1 D protocol stacks without external memory. The 2.0 V to 5.5 V supply supports 3.3 V regulated designs and 5 V USB-powered fixtures without a separate supervisor.
Recommended
Battery-Powered Sensor Conditioning
The PIC16F716-I/ML is a strong fit for battery-powered sensor conditioning where its 2.0 V to 5.5 V supply lets it run directly from a single lithium cell down to cutoff. The 4 ADC channels sample thermistors, photodiodes, or strain gauges with 8-bit resolution sufficient for threshold-based decisions. The internal 8 MHz oscillator eliminates external crystals, reducing BOM cost and quiescent draw in sleep. With 25 mA I/O capability the device can directly drive status LEDs and a low-side MOSFET for load switching. The 128-byte EEPROM stores calibration constants across power cycles.
Recommended
Small Motor and Fan Control (BLDC / Brushed)
The PIC16F716-I/ML fits small BLDC, brushed DC, and fan-control boards where its Enhanced CCP module generates complementary PWM with programmable dead-band, eliminating external half-bridge driver logic. The 25 mA I/O can directly switch low-side MOSFETs in sub-1 A applications, or drive gate-driver ICs in higher-current designs. The 16-bit timer with hardware capture enables back-EMF sensing and RPM measurement. With 3.5 KB flash, sensored or sensorless FOC-firmware variants fit on this part, and the 2.0 V to 5.5 V supply lets the same firmware run on 3.3 V or 5 V motor rails.
Recommended
Automotive Body Electronics and Lighting
The PIC16F716-I/ML family is AEC-Q100 capable for automotive body-electronics modules where its 4 ADC channels read switch positions, potentiometer inputs, and battery voltage, and the ECCP drives LED tail-lights or small motors. The -40C to +125C extended grade PIC16F716-E/ML variant handles underhood and cabin thermal stress. The 2.0 V to 5.5 V supply survives crank-start transients when paired with a TVS diode and bulk capacitor. With AUSART, the part interfaces to body-control modules over LIN-bus transceivers for diagnostic and firmware-update paths in production vehicles.
Recommended
Industrial Metering and Front-End Signal Conditioning
The PIC16F716-I/ML fits industrial metering front-ends where its 4 ADC channels sample current transformers, shunt resistors, or analog sensor outputs and the AUSART streams readings to a host processor. The 2.0 V to 5.5 V supply lets the device run on 3.3 V or 5 V industrial rails. The Enhanced CCP module produces precision PWM for valve control or 4-20 mA loop excitation with dead-band adjustment. With 3.5 KB flash, calibration routines, linearization tables, and Modbus RTU framing fit on-chip. The internal 8 MHz oscillator eliminates external crystals in cost-sensitive metering products.
Recommended
Small Appliance and Consumer Control Boards
The PIC16F716-I/ML fits small appliance and consumer control boards where its 25 mA I/O directly drives seven-segment LEDs, relays, and buzzer transducers, and the ECCP module generates PWM for heating-element proportional control or fan-speed regulation. The 4 ADC channels read thermistor temperature inputs, water-level probes, and user-interface potentiometers. With 128-byte EEPROM, the device stores user-set temperatures and run-cycle counters across brownout events. The 2.0 V to 5.5 V supply supports universal 3.3 V or 5 V designs, and the 28-QFN 6x6 mm footprint fits compact appliance-control PCBs.

Key Differentiators
- Enhanced CCP with dead-band control for direct half/full-bridge drive (vs PIC16F616-I/ML)
- Higher ADC channel count and resolution (vs PIC16F688-I/SL)
- Extended temperature grade variant available (vs PIC16F716-E/ML)
Design Notes
The 28-QFN (6x6 mm) package dissipates heat primarily through the exposed thermal pad on its underside. The pad MUST be soldered to a ground-copper pour of at least 1 square inch with a 4-via thermal array (0.3 mm drill, 0.5 mm pitch) for the part to meet its rated electrical performance. Without a thermal pad connection, junction temperature can rise 30-50 C above ambient under sustained PWM load, potentially triggering thermal-shutdown behavior. X-ray inspection after reflow is recommended for hidden solder joints under the exposed pad.
Decouple VDD with a 100 nF ceramic capacitor placed within 3 mm of the VDD pin (pin 20), plus a 10 uF bulk capacitor on the same net for switching transients. The VSS pin (pin 19) should connect to the same ground pour as the thermal pad with a short, low-inductance path. Place the ADC Vref antenna noise reduction on a separate analog ground island if the ADC accuracy is critical, joined to the digital ground at a single point under the IC.
Do not exceed 5.5 V on VDD or drive any I/O above VDD or below VSS - this clamps protection diodes and can cause latch-up. The PVCC pin (not present on 28-QFN) requires external 5 V for gate drivers on larger packages; on this 28-QFN variant, VDD supplies both logic and I/O. Configure unused I/O as outputs (low) rather than inputs to avoid floating-pin current draw of 1-2 mA per pin. The ICD/ICSP programming pins RB6 and RB7 are shared with in-circuit debugging and require isolation resistors if external pull-ups are present.
