PIC16F1707-E/ML Overview
An 8-bit PIC microcontroller is a Harvard-architecture CMOS device that executes a reduced instruction set (RISC) optimized for embedded control. PIC microcontrollers are widely used in consumer, industrial, and IoT applications because they pair deterministic interrupt response with low power consumption. Within Microchip's portfolio, the PIC16F1707 sits in the mid-range PIC16F1xxx family - positioned between baseline PIC10/12/16 devices and higher-end PIC18/PIC24 parts - and belongs to the XLP (eXtreme Low Power) sub-line, with idle currents in the microampere range.
Key features include 3.5KB self-programmable flash, 256B SRAM, two op amps with configurable rails, a 10-bit ADC up to 28 channels, PWM, CCP, EUSART, I2C/SPI, and nanoWatt XLP sleep currents down to 20 nA typical. The integrated COG and ZCD make it well suited to motor control, TRIAC/SSR driving, and zero-cross switching applications that previously required a dedicated analog front end. The 20-pin QFN 4x4 mm footprint is among the smallest in the PIC16 line, making it attractive for space-constrained designs.
Typical applications include LED lighting ballast, AC zero-cross switching, low-end BLDC/PMSM commutation assist, battery-powered sensor nodes, and consumer white-goods user-interface controllers. Design considerations include ensuring adequate ground copper under the exposed pad of the QFN for thermal dissipation and using the PPS feature to remap peripheral I/O to convenient package pins.

Typical Applications
PIC16F1707-E/ML is suitable for 6 applications: AC Zero-Cross Switching / TRIAC Driver, LED Lighting Ballast and Color Mixing, Battery-Powered IoT Sensor Nodes, Low-End BLDC/PMSM Commutation Assist, Consumer White-Goods User Interface, Automotive Body and Convenience Modules.
AC Zero-Cross Switching / TRIAC Driver
The PIC16F1707's integrated Zero-Cross Detect (ZCD) peripheral simplifies mains AC zero-cross switching for TRIAC or SSR control in dimmers, motor starters, and solid-state relays. Place the ZCD input across a resistor-bridged mains sample so the controller knows the AC phase reference; the Complementary Output Generator (COG) can then produce precisely timed gate pulses without CPU intervention, reducing EMI. Compared with discrete zero-cross detector ICs, this integration removes external comparators and lets the core stay in sleep mode for microampere-class standby current - a strong fit for always-on smart switches.
Recommended
LED Lighting Ballast and Color Mixing
With two on-chip op amps, a 10-bit ADC2 with computation, and PWM outputs, the PIC16F1707 can condition photodiode feedback and drive constant-current LED strings with closed-loop regulation. The 32MHz instruction rate supports up to 20kHz PWM for flicker-free dimming, while nanoWatt XLP sleep drops quiescent current to about 20 nA for off-state efficiency. The QFN-20 4x4 mm footprint fits inside E27 bulbs and T8 tube replacements, making the part attractive for high-density smart-lighting designs that demand analog precision in a small board area.
Recommended
Battery-Powered IoT Sensor Nodes
The PIC16F1707 is engineered for battery-powered IoT sensor nodes that demand multi-year battery life: nanoWatt XLP provides 20 nA sleep typical, while core-independent peripherals (COG, ZCD, ADC2) allow the CPU to remain dormant while data acquisition runs. A EUSART-based UART-WiFi or UART-LoRa link can wake the core briefly to transmit, and 256B SRAM is sufficient for short sensor bursts. The QFN-20 4x4 mm package enables coin-cell-powered designs for HVAC, leak detection, or asset tracking where every square millimeter of PCB matters.
Recommended
Low-End BLDC/PMSM Commutation Assist
In low-end BLDC and PMSM motor designs, the PIC16F1707 serves as a commutation-assist controller alongside a dedicated gate driver, using its Complementary Output Generator to produce precisely timed high-side/low-side PWM with dead-band control. The 10-bit ADC reads back-EMF or shunt current for sensorless commutation, while the on-chip op amps condition the signal directly - eliminating an external analog front end. The QFN-20 footprint integrates into compact fan controllers, small appliance motors, and 12V-class pump drives.
Recommended
Consumer White-Goods User Interface
The PIC16F1707 is well suited for user-interface controllers in washing machines, dishwashers, microwave ovens, and coffee machines, where its Peripheral Pin Select (PPS) allows flexible PCB routing of buttons, rotary encoders, displays, and buzzers. The 32MHz CPU drives segmented or character LCDs via software I2C/SPI, and the two on-chip op amps can read temperature from NTC thermistor dividers with no external analog IC. RoHS compliance and a -40C to +125C temperature range meet the harsh under-cabinet thermal environment typical of white goods.
Recommended
Automotive Body and Convenience Modules
In automotive body controllers, climate-control interfaces, and accessory modules, the PIC16F1707's -40C to +125C operating range and integrated analog peripherals reduce BOM cost versus discrete solutions. The ADC2 with computation handles battery voltage monitoring, while PWM drives small loads such as LED interior lighting or mirror heaters. The QFN-20 4x4 mm package supports miniaturized PCBAs behind door handles, overhead consoles, and rear-view mirrors where automotive OEMs demand compact, low-power microcontrollers with deterministic interrupt response.

- Two on-chip op amps without increasing flash footprint (vs PIC16F1575-E/ST)
- Lower flash footprint for cost-sensitive 8-bit designs (vs PIC16F1713-I/ML)
- nanoWatt XLP sleep current at 20 nA typical (vs PIC16F1705T-I/ML)
Design Notes
The 20-pin QFN (4x4 mm) package exposes a thermal/ground pad on the underside. Solder paste coverage of at least 60% of this EP pad is recommended to achieve the datasheet thermal resistance and a reliable ground return. Add thermal vias in the EP pad region (typical 4-9 vias at 0.3 mm drill) tied to the inner ground plane. Skip the EP solder connection only when the datasheet allows it - for the PIC16F1707 it must be soldered for thermal dissipation and electrical ground.
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin (pin 7), with the loop area minimized to suppress high-frequency noise. Add a bulk capacitor of 1-10 uF near the IC if the supply is shared with analog peripherals. The PIC16F1707 nanoWatt XLP mode draws down to about 20 nA in sleep, so the decoupling network must release charge fast enough to support wake-up transients - prefer X7R or X5R ceramics over Y5V.
For designs that use the on-chip op amps in front of the ADC, route analog traces away from digital switching lines such as PWM and SPI clock. Use a ground-star or partitioned analog/digital ground scheme with a single point join near the IC. The ZCD input pin (RA3) is sensitive to fast edges - place a small RC filter (typically 100 kohm + 100 pF) at the pin when probing mains voltages directly to limit dv/dt and false triggering.
Do not confuse the -E industrial temperature grade (-40C to +125C) with the -I grade (-40C to +85C); both share the same QFN-20 /ML package but the temperature range affects AEC-Q100 suitability. The PIC16F1707 is not AEC-Q100 qualified - choose AEC-Q100-grade PIC16F1xxx variants for automotive designs. When migrating firmware from PIC16F1507 to PIC16F1707, verify that COG and ZCD peripheral registers are mapped correctly; the PPS unlocking sequence (PPSLOCK) must be used when remapping pins.
Estimated: At maximum 32MHz CPU activity, 3.3V VDD, and full peripheral enablement, the PIC16F1707 draws approximately 7 mA, which yields about 23 mW of dissipation - well within the QFN-20 thermal envelope. With the EP pad properly soldered to ground copper of at least 100 mm^2, the junction-to-ambient thermal resistance stays around 40 C/W, giving a ~0.9 C rise above ambient. Designers running the part at +125C ambient should still confirm EP solder coverage and derate CPU activity if forced convection is absent.
Compliance Information
RoHS and lead-free compliant per Microchip product page. Not AEC-Q100 qualified; the -E suffix indicates -40C to +125C industrial temperature grade only. For AEC-Q100 automotive applications, select a PIC16F1xxx part number specifically flagged with the Q-Automotive designation.
