PIC16LF1847T-I/MV Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, typically optimized for low-power, deterministic, cost-sensitive embedded control tasks. PIC microcontrollers occupy the wider taxonomy of microcontroller -> embedded processor -> integrated circuit -> semiconductor. The PIC16F/LF1847 family in particular targets ultra-low-power applications, leveraging Microchip's nanoWatt XLP technology that delivers deep-sleep currents in the nanoamp range, making this category a strong fit for battery-powered sensor nodes, wearables, and energy-harvesting endpoints.
Key features of the PIC16LF1847T-I/MV include the integrated mTouch capacitive-touch sensing peripheral, the XLP nanoWatt extreme-low-power technology with multiple idle/sleep modes, an on-chip 32 MHz internal oscillator eliminating the need for external crystals in many designs, and a wide operating voltage range from 1.8 V to 3.6 V suitable for Li-ion and coin-cell supplies. The device also integrates Core Independent Peripherals (CIPs) such as CWG, NCO, DSM, and configurable logic cells that offload timing-critical tasks from the CPU, freeing the core for application logic.
Architecturally the device implements the enhanced mid-range core with C-compiler-optimized instruction set, supporting linear program and data memory addressing of up to 14 KB and 1 KB respectively, automatic context saving on interrupts, and direct/indirect/relative addressing modes. This combination reduces firmware complexity while enabling deterministic interrupt response.
Typical applications include capacitive-touch human-machine interfaces (keypads, sliders, proximity sensors), battery-powered IoT sensor nodes, low-power remote controls, wearables and fitness bands, energy-harvesting wireless sensor endpoints, and small appliances requiring mTouch buttons or sliders.
When designing with this part, note that the LF prefix denotes the low-voltage variant (1.8 V to 3.6 V), while the non-LF PIC16F1847 operates from 1.8 V to 5.5 V. The "T" suffix in PIC16LF1847T-I/MV denotes Tape and Reel packaging. Use MPLAB X IDE with the XC8 compiler for development.

Typical Applications
PIC16LF1847T-I/MV is suitable for 6 applications: Capacitive-Touch User Interface, Battery-Powered IoT Sensor Nodes, Wearable Fitness and Health Bands, Low-Power Remote Controls, Energy-Harvesting Wireless Switches, Small Appliance Control.
Capacitive-Touch User Interface
The PIC16LF1847T-I/MV is purpose-built for capacitive-touch HMIs thanks to its integrated mTouch peripheral, which supports buttons, sliders, and proximity sensors without external touch ICs. The device's 32 MHz CPU and CIPs (Configurable Logic Cells, NCO, DSM) handle real-time touch scanning and noise-immunity algorithms while keeping CPU load under 20 percent. The XLP nanoWatt technology delivers deep-sleep currents below 100 nA, so a battery-powered keypad or remote control can run for years on a single coin cell. This part is preferred over discrete touch controllers because it integrates ADC, timers, communication peripherals (I2C/SPI/EUSART), and touch acquisition into one chip, reducing BOM and PCB area.

Battery-Powered IoT Sensor Nodes
The PIC16LF1847T-I/MV is a strong fit for IoT sensor endpoints thanks to its 1.8 V to 3.6 V operating range that aligns directly with single-cell Li-ion, two-cell coin-cell, and energy-harvesting rails. NanoWatt XLP technology drops sleep current into the nanoamp range, enabling multi-year battery life on periodic sensor readings. The 14 KB Flash and 1 KB SRAM comfortably run sensor drivers, calibration tables, and lightweight wireless protocol stacks (LoRa, BLE-managed-host). The 28-UQFN 4x4 mm package is small enough for sub-1 cubic-inch sensor enclosures, and the internal 32 MHz oscillator removes the crystal BOM. Pair this MCU with a sub-GHz or BLE transceiver for a complete energy-efficient wireless node.
Recommended
Wearable Fitness and Health Bands
Wearables demand tiny packages, low quiescent current, and integrated touch plus ADC peripherals, all of which the PIC16LF1847T-I/MV delivers in a 4x4 mm UQFN. Its 12-bit ADC (channel count per datasheet) captures heart-rate, skin-temperature, and motion-related analog signals, while the mTouch peripheral handles swipe and tap gestures on band enclosures. XLP deep-sleep current in the nanoamp range keeps standby battery drain negligible between active measurements, and the 1.8 V minimum VDD supports direct Li-ion or rechargeable coin-cell chemistries without an LDO. The 14 KB Flash accommodates lightweight BLE host stacks or proprietary RF firmware.
Recommended
Low-Power Remote Controls
IR/RF remote controls benefit from the PIC16LF1847T-I/MV's combination of sub-microamp sleep current, mTouch buttons, and integrated PWM for IR carrier generation. Battery life extends to multiple years on a single coin cell thanks to XLP modes that power down the core while keeping wake-on-touch and IR-receive interrupts active. The 32 MHz internal oscillator and configurable logic cells handle NEC/SIRC RC5/RC6 protocol encoding in firmware without external timing ICs. The compact 28-UQFN fits inside thin remote enclosures, and Microchip's mature MPLAB X toolchain with the FREE XC8 compiler enables fast firmware iteration.
Recommended
Energy-Harvesting Wireless Switches
Self-powered wireless light switches and IoT buttons generate brief energy pulses from a piezoelectric or micro-generator tap, which must be conditioned by an MCU with very low startup voltage and fast wake time. The PIC16LF1847T-I/MV operates down to 1.8 V and wakes from sleep in microseconds, allowing a single harvested pulse to power a complete sub-GHz or BLE transmission. NanoWatt XLP sleep currents below 100 nA minimize quiescent loss between user presses, and the on-chip 32 MHz oscillator eliminates the external crystal wake-time penalty. The 14 KB Flash holds stack and pairing tables for EnOcean, Zigbee Green Power, or proprietary protocols.
Recommended
Small Appliance Control
Kitchen appliances, fans, coffee machines, and small white goods benefit from the PIC16LF1847T-I/MV's balance of GPIO, touch input, ADC for temperature sensing, and PWM for motor or heater control. The integrated Core Independent Peripherals (CWG, NCO, DSM) generate accurate motor-drive waveforms without CPU intervention, freeing the core for safety checks, user interface, and sensor polling. The 28-UQFN footprint allows compact mainboards for slim product enclosures, and the industrial -40 C to +85 C temperature rating handles appliance operating environments. Production firmware is supported by Microchip's MPLAB Code Configurator (MCC) for rapid peripheral setup.

Key Differentiators
- Integrated mTouch capacitive touch peripheral (vs PIC16LF1826-E/MV)
- More Flash memory for richer firmware (vs PIC16LF1782T-I/MV)
- Lower voltage rail for battery-only designs (vs PIC16F1847T-I/MV)
- Best balance of memory and touch integration (vs PIC16LF1718T-I/MV)
Design Notes
Take advantage of nanoWatt XLP sleep modes to minimize system current. Configure unused peripherals to off-state in firmware, select the lowest-power SLEEP variant that retains required RAM, and gate the mTouch scan engine with a low-frequency timer to avoid continuous scanning. In designs that wake periodically to transmit, expect overall average current in the single-digit microamp range when transmit duty is below 0.1 percent.
The 28-UQFN (4x4) package exposes a center thermal pad that MUST be soldered to a sufficiently large ground copper pour on the top or bottom layer. This serves both as the primary thermal dissipation path and the low-impedance ground return. Route VDD/VSS as wide traces or pours, place the decoupling capacitor (100 nF X7R + 1 uF X5R) within 2 mm of the VDD pin, and avoid routing high-frequency signals under the package to minimize coupling into analog CPS channels.
Do not exceed the 3.6 V absolute maximum on VDD even for transient spikes; the LF variant is not 5 V tolerant. Always enable the PIC16 hardware BOR (Brown-Out Reset) at a threshold appropriate for your battery chemistry to prevent code execution at unsafe supply voltages. For mTouch designs, add a guard ring around CPS traces and ensure the touch electrode-to-MCU trace length is kept short to minimize noise pickup from inverters or switching converters.
Place the ICSPDAT/ICSPCLK lines (RB6/RB7) on PCB test-point pads so the MPLAB Snap, PICkit 4, or ICD 4 can program and debug the device without rework. Isolate the mTouch CPS traces from noisy digital traces by routing them on a different layer or with a guard ground. Keep the MCLR/VPP line short and avoid capacitive loading above 50 pF to ensure reliable ICSP programming in production.
