PIC16F707-I/ML Overview
What is a PIC16F 8-bit microcontroller? A PIC microcontroller is a family of RISC-based, Harvard-architecture 8-bit microcontrollers from Microchip Technology that combine a CPU core, on-chip flash/RAM/EEPROM, peripherals, and I/O into a single IC. Within this taxonomy the PIC16F sub-family sits between the baseline PIC10/12/16 and the higher-end PIC18/PIC24 families, optimized for cost-sensitive, low-power embedded designs. The PIC16F707 belongs to the eXtreme Low Power (XLP) "nanoWatt XLP" tier, positioning it as a power management IC for battery- and energy-harvesting systems where microamp-level sleep currents matter.
Key features include 32 channels of Capacitive Sensing (mTouch) peripheral for touch-button or proximity interfaces, an LCD driver supporting up to 116 segments, two Enhanced USART modules, two SPI/I2C modules, up to 14 channels of 10-bit ADC, and four 8-bit/16-bit timers. The nanoWatt XLP technology delivers sub-microamp sleep currents, while the part is rated for industrial -40C to +85C operation under the -I speed/temperature grade.
The PIC16F707 executes a single-cycle 35-instruction RISC instruction set with a 14-bit program word and an 8-level hardware stack. Internal oscillator calibration eliminates external resonator cost on simple designs, while the ICD/ICSP programming/debug interface and integrated peripheral pin select simplify bring-up. The architecture is well-suited to driving mTouch capacitive sensing, LCD bias, and standard digital interfaces in parallel on a small PCB footprint.
Typical applications include low-power human-interface panels with capacitive touch, battery-powered home automation nodes, white-goods and appliance control boards, industrial sensor front-ends, and small-format LCD-display embedded modules. The 32 mTouch channels and integrated LCD driver make it particularly strong where cost, BOM count, and standby power matter simultaneously. Design considerations include thermal performance of the 5x5 mm UQFN EP land pad for heat extraction, mandatory ICSP programming pin allocation (PGD/PGC reserved regardless of I/O count), and ensuring the decoupling/VDD/VSS layout follows Microchip's recommended ground-grid pattern for ADC noise floor performance.

Typical Applications
PIC16F707-I/ML is suitable for 6 applications: Capacitive Touch Human Interface Panels, Battery-Powered Home Automation Nodes, White Goods and Appliance Control Boards, LCD-Display Embedded Modules, Industrial Sensor Front-Ends, Small Consumer Electronics and Toys.
Capacitive Touch Human Interface Panels
The PIC16F707-I/ML's 32 mTouch channels allow up to 32 individual touch buttons, sliders, or proximity zones without external controller ICs. Combined with the 14 KB flash and the integrated CSM peripheral, the MCU handles capacitive sensing scans, debounce, and gesture interpretation entirely on-chip. Its nanoWatt XLP sleep currents below 1 uA mean a battery-powered touch keypad can sit idle for months without recharge. Place guard rings, driven shields, and ground floods per Microchip TB1108 for EMC-robust sensor performance.
Recommended
Battery-Powered Home Automation Nodes
Sub-microamp sleep current and 1.8 V-3.6 V operation on the PIC16LF707 sister part make this family ideal for battery-powered wireless sensor nodes, smart-home buttons, and energy-harvesting switches. The 14 KB flash is sufficient for Zigbee/Z-Wave/BLE-stack-free RF link layers when paired with an external radio such as the MRF24, the RN2483 LoRa, or ATSAMR21 modules. The 256-byte EEPROM stores network credentials and last-state memory across battery swaps.
Recommended
White Goods and Appliance Control Boards
The PIC16F707-I/ML's 36 I/O pins, 14 ADC channels, and ECCP PWM support direct interfacing with TRIAC drivers, relay coils, and tri-color LED indicators typical of washing machines, microwave ovens, and dishwashers. nanoWatt XLP keeps standby power below energy-star limits. The UQFN-44 EP exposed pad offers thermal relief for switching-supply co-location. Use optocouplers such as MOC3021 for mains-isolated control interfaces per safety certification needs.
Recommended
LCD-Display Embedded Modules
Integrated LCD driver supporting up to 116 segments eliminates external HT1621 or PCF8576 LCD-driver chips, reducing BOM by $0.40-$0.80 per board. The 32 mTouch channels allow capacitive touch overlay on the LCD glass. Common designs include thermostats, water-heater controllers, weighing scales, and instrumentation front panels. Drive segment traces with adequate clearance per datasheet section 26 to avoid ghosting on multi-segment displays.
Recommended
Industrial Sensor Front-Ends
Up to 14 channels of 10-bit ADC let the PIC16F707-I/ML multiplex multiple analog sensors such as temperature, pressure, and humidity on a single MCU. The two EUSART and two MSSP peripherals support RS-485 sensor networks, I2C sensor hubs, and SPI ADC chains simultaneously. The -40C to +85C industrial temperature grade supports factory-floor installations, and nanoWatt XLP enables 4-20 mA loop-powered sensor nodes with year-long battery life.
Recommended
Small Consumer Electronics and Toys
The PIC16F707-I/ML's low cost (USD 2.04 at 1000 pieces as of 2026-09-21) and 20 MHz performance support feature-rich consumer products including electronic toys, e-readers, fitness bands, and remote controls. The mTouch peripheral enables capacitive touch buttons on sealed plastic enclosures, while the LCD driver powers low-cost segment displays. Pair with external flash like SST26VF016 for audio sample storage or BLE modules for wireless connectivity.

Key Differentiators
- Highest mTouch channel count in the PIC16F XLP family at the same UQFN-44 EP footprint (vs PIC16F690-I/ML)
- Integrated LCD segment driver eliminating external HT1621-class controllers (vs PIC16F690-I/ML)
- Twice the flash and RAM versus the closest pin-compatible alternative (vs PIC16F690-I/ML)
Design Notes
The UQFN-44 EP exposed thermal pad MUST be soldered to a continuous ground plane on the PCB for electrical and thermal performance. Use at least 4 thermal vias (0.3 mm drill, 0.6 mm pad) connecting the EP to inner ground planes. The pin 1 indicator is a small notch on the package edge; do not rely on silkscreen orientation alone when hand-soldering prototypes. Decoupling: place 100 nF X7R ceramic directly between VDD and VSS pins (21/22 and 42/43), within 3 mm of the IC, plus a bulk 4.7 uF tantalum or ceramic on the main VDD rail.
ICSP pins PGD (RB7) and PGC (RB6) are shared with general I/O. If your PCB design routes these pins to drive external loads (LEDs, relays, or other low-impedance loads), ICSP programming will fail. Reserve a 2x1 or 1x3 header footprint for the ICSP connector and ensure PGD/PGC pins see only high-impedance signals or are isolated by 0 ohm jumpers during production programming. Never use MCLR/VPP as a general-purpose I/O on the PIC16F707 because MCLR is required for ICSP and reset generation.
When designing mTouch capacitive touch sensors, follow Microchip application note TB1108 guidelines. Place a driven shield ring around each touch sensor pad, with the shield track connecting to a dedicated CPS shielding channel. Keep ground fills at least 5 mm away from sensor pads to prevent parasitic capacitance that lowers sensitivity. Use a 100 nF X7R bypass capacitor on each AVSS pin used for ADC measurements, and average at least 16 ADC samples for stable readings on noisy industrial systems.
Estimated: At 20 MHz CPU clock and 5.5 V VDD, the PIC16F707-I/ML dissipates approximately 30 mW to 80 mW typical (varies with peripheral activity). The UQFN-44 EP 5x5 mm package has theta_JA around 35 C/W on a standard 4-layer 1 oz copper JEDEC test board. Junction temperature rise above ambient is therefore approximately 1-3 C, well within the 125 C max junction. Estimated input values: IDD 15 mA active at 5.5 V per datasheet typical characteristics.
