PIC16F1847T-I/ML Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, optimized for low-cost, low-power, deterministic embedded control. PIC16F1847T-I/ML sits in the broad hierarchy: 8-bit MCU -> PIC16 family -> enhanced mid-range core -> flash microcontroller -> embedded processor. The ‘XLP’ (eXtreme Low Power) designation places it within a sub-family engineered for sleep currents in the tens of nanoamperes, suitable for battery-powered and energy-harvesting endpoints.
Key features of PIC16F1847T-I/ML include 16 enhanced I/O pins, on-chip 32kHz internal oscillator, configurable logic cells (CLC), multiple PWM modules, two I2C/SPI interfaces, one USART, an integrated debug port supporting PICkit 3 and MPLAB ICD 3, and automotive- and industrial-grade -40C to +85C operating range. The 28-QFN (6x6 mm) package adds an exposed thermal pad for improved dissipation and a small PCB footprint.
Architecturally, the device uses a 14-bit instruction word with a two-stage pipeline, supports self-programmability via ICSP, and offers peripheral pin select (PPS) for flexible signal routing. The 12-bit ADC and 10-bit PWM are well matched to closed-loop motor, lighting, and sensor conditioning tasks.
Typical applications include capacitive touch user interfaces (mTouch), battery-powered sensor nodes, consumer white goods, low-cost HVAC controls, and industrial instrumentation. The wide 2.5V–5.5V operating range and integrated peripherals allow direct connection to 3.3V or 5V sensors.
When designing with this MCU, verify your toolchain against the device family header; MPLAB X IDE plus XC8 compiler is the recommended development environment. Place the exposed pad on a continuous ground copper pour for thermal relief and signal integrity.

Typical Applications
PIC16F1847T-I/ML is suitable for 6 applications: Capacitive Touch User Interface (mTouch), Battery-Powered Wireless Sensor Node, Industrial HVAC and Sensor Conditioning, Consumer White Goods Control Board, Low-Cost LED Lighting Controller, Automotive Body Electronics (non-safety).
Capacitive Touch User Interface (mTouch)
The PIC16F1847T-I/ML integrates Microchip’s mTouch capacitive-sensing peripheral and a 12-bit ADC, enabling reliable button, slider, and proximity sensing without external touch ICs. Its 32 MHz core completes touch scans in microseconds while XLP nanoWatt sleep modes keep idle power under 50 nA for battery-powered remotes, white-goods control panels, and IoT wall switches.
Recommended
Battery-Powered Wireless Sensor Node
The PIC16F1847T-I/ML is well suited to host low-power sensor endpoints communicating via UART-attached BLE or sub-GHz radio modules. The XLP sleep current in the tens of nA combined with 14KB of Flash supports application stacks such as 6LoWPAN edge nodes, while the integrated 12-bit ADC reads thermistor or battery-sense signals directly without external components.
Recommended
Industrial HVAC and Sensor Conditioning
The PIC16F1847T-I/ML’s industrial -40C to +85C operating range, 12-bit ADC, and PWM outputs make it a strong fit for HVAC damper actuators, thermostat boards, and 4-20 mA loop interfaces. Its USART easily bridges to RS-485 transceivers, while the 32 MHz core runs proportional control loops at ample sample rate for smooth fan or valve modulation.
Recommended
Consumer White Goods Control Board
Inside washing machines, refrigerators, and microwaves, the PIC16F1847T-I/ML drives inverter-controlled motors, BLDC fans, and LED display arrays. The combination of 16 enhanced I/O pins, multiple PWM channels, and PPS signal routing simplifies PCB layout when interfacing triac drivers, EEPROM, and keypad matrices typical of white-goods boards.
Recommended
Low-Cost LED Lighting Controller
The PIC16F1847T-I/ML powers color-mixing and dimming control for architectural and accent lighting. Its 10-bit PWM (or higher) channels provide smooth dimming curves, while the integrated 5-bit DAC can generate reference voltages for LED driver ICs. XLP sleep extends battery life on wireless wall-switch retrofits to multi-year operation.
Recommended
Automotive Body Electronics (non-safety)
Although the PIC16F1847T-I/ML is industrial-grade, it is widely used in 12V body modules such as seat controllers, mirror adjusters, and interior lighting drivers. The 32 MHz core handles LIN slave protocol stacks and the 12-bit ADC reads potentiometer positions for seat-memory functions; AEC-Q100 variants are separately offered in the same family.

Key Differentiators
- Largest memory in 28-QFN PIC16F1847 family (vs PIC16F1829T-I/ML)
- Industrial-grade temperature rating (vs PIC16F1847-E/P)
- Tape-and-reel packaging for SMT assembly (vs PIC16F1847-I/ML)
- mTouch capacitive sensing peripheral (vs PIC16F1827T-I/ML)
Design Notes
Estimated: At 32 MHz and 5V VDD with all peripherals active, PIC16F1847T-I/ML draws approximately 6-8 mA typical. In XLP Sleep mode with WDT disabled, current drops below 100 nA. Add a 100 nF decoupling capacitor within 3 mm of each VDD/VSS pair, plus a 10 uF bulk capacitor on the VDD rail to suppress inrush during ADC sampling.
The 28-QFN exposed thermal pad (EP) MUST be soldered to a continuous ground copper pour of at least 25 mm^2 for mechanical reliability and thermal dissipation. Stencil apertures of 1:1 ratio on the EP with multiple smaller openings improve voiding. Avoid running signal traces beneath the EP - this compromises solder joint inspection.
When migrating PIC16F1847T-I/ML code from an 18-pin PIC16F1827 or similar, the 28-QFN part exposes additional I/O pins that the linker script may leave uninitialized, causing floating inputs and excess current. Always configure PPS registers before enabling peripherals, and use the MPLAB Code Configurator to generate the configuration bits for the -I/ML industrial variant.
Keep the ICSP signals PGC (RB6) and PGD (RB7) accessible on test points or an unpopulated header for in-circuit debugging. The MCLR/RA5/VPP pin requires a 10 kohm pull-up to VDD and a 100 nF cap to ground; without this, false reset events can occur during power-up ramp. Reserve RB6/RB7 even if not used for GPIO - they are required for ICSP.
Compliance Information
RoHS and lead-free per Microchip product page. Industrial-grade -I temp range (-40C to +85C), not AEC-Q100 qualified - choose PIC16F1847T-E/ML for extended-temp applications.
