PIC16LF1827T-I/MV Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O onto one silicon die. The PIC16 family uses Microchip's enhanced mid-range 8-bit RISC architecture, with single-cycle instruction execution at 200ns and 49 instruction opcodes that simplify code generation. Positioned in the hierarchy as PIC16 -> PIC mid-range -> 8-bit MCU -> microcontroller -> semiconductor, the LF (low-power F) variant is optimized for battery-operated designs through nanoWatt XLP technology offering sleep currents as low as 20nA.
Key features include 7KB (4K x 14 words) Flash program memory, 384 bytes RAM, 256 bytes EEPROM, 16 I/O pins, integrated capacitive touch (mTouch) sensing, 10-bit ADC with up to 12 channels, two 8-bit and two 16-bit timers, two comparators, and master I2C/SPI/EUSART peripherals. The device supports 1.8V to 3.6V operation with active current of approximately 4 mA at 32 MHz, enabling direct Li-Ion or 2xAA battery connection without external regulation.
The PIC16LF1827T-I/MV uses Microchip's enhanced mid-range core with hardware multiplier, providing deterministic interrupt response and code-compatible migration to larger PIC16 variants. The internal 32MHz oscillator eliminates the need for an external crystal in cost-sensitive designs, while the nanoWatt XLP technology enables years of operation from a single coin cell in sleep-dominated applications.
Typical applications include consumer touch-interface products (appliance controls, toys, remote controls), portable battery-powered instrumentation, sensor nodes for IoT, low-end wearable devices, and capacitive touch user interface panels. The wide 1.8V-3.6V operating range makes it well-suited for direct connection to single-cell Li-Ion or two-AA battery stacks.
When designing with this part, leverage the XLP sleep modes to maximize battery life, and place a 0.1uF decoupling capacitor within 5mm of the VDD pin. The UQFN EP package requires thermal pad soldering for proper thermal and electrical performance.

Typical Applications
PIC16LF1827T-I/MV is suitable for 6 applications: Capacitive Touch User Interface, Battery-Powered IoT Sensor Node, Consumer Remote Control, Small Appliance Control Board, Portable Health Wearable, LED Lighting Controller.
Capacitive Touch User Interface
The PIC16LF1827T-I/MV is purpose-built for capacitive touch human-machine interfaces thanks to its integrated mTouch peripheral and 16 GPIO channels. The mTouch module supports up to 12 touch buttons via dedicated CTMU-based charge-time measurement, eliminating the need for an external touch controller IC and reducing BOM cost by approximately USD 0.30-0.50 per board. Operating from 1.8V-3.6V with 4 mA active current at 32MHz, the LF variant supports years of battery operation between touch events. Its 7KB Flash and 384B RAM are sufficient to store a full touch UI state machine plus communication stacks for SPI or I2C OLED displays, making it ideal for appliance control panels, smart locks, and remote control products.
Recommended
Battery-Powered IoT Sensor Node
The PIC16LF1827T-I/MV is well suited for wireless sensor nodes where multi-year battery life from a single coin cell is required. The nanoWatt XLP technology delivers sleep currents in the 20-100 nA range with multiple low-power modes (doze, idle, sleep), and the 1.8V-3.6V operating range allows direct connection to a single CR2032 or two-AA cells without voltage regulation. The 10-bit ADC with up to 12 channels handles temperature, humidity, and battery voltage monitoring, while the integrated I2C/SPI/EUSART peripherals interface to sensors and sub-GHz radios like the MRF89XA. Estimated runtime for a 1% duty-cycle wake/sleep pattern at 220 mAh CR2032 is in the 3-5 year range.
Recommended
Consumer Remote Control
The PIC16LF1827T-I/MV is widely deployed in handheld remote controls for TVs, set-top boxes, and consumer audio equipment. Its 32MHz internal oscillator eliminates the need for an external crystal, reducing BOM cost and PCB area, while the 7KB Flash is sufficient to encode IR, RF4CE, or Bluetooth Low Energy command protocols. The low 1.8V minimum VDD allows use of a single CR2032 coin cell, while the XLP sleep current extends battery life to multi-year timeframes between user button presses. The integrated comparators and timers support capacitive or mechanical keypad scanning without external glue logic.
Recommended
Small Appliance Control Board
The PIC16LF1827T-I/MV is a strong fit for small household appliances such as coffee makers, blenders, and air purifiers that require low-cost capacitive touch interfaces and motor control. The 10-bit ADC handles temperature and current sensing, while the PWM module and comparators drive TRIAC or FET-based heater/motor power stages. The 28-UQFN EP 4x4mm package has a small PCB footprint suitable for dense consumer product layouts. The integrated mTouch and EEPROM simplify capacitive button UI plus non-volatile storage of user preferences (brew strength, fan speed) without external memory.
Recommended
Portable Health Wearable
The PIC16LF1827T-I/MV is suitable for entry-level wearable health devices such as step counters, heart-rate straps, and pill reminders where battery life and small PCB area are paramount. Its 1.8V-3.6V single-cell operation, low active current, and integrated sleep modes support 6-12 month battery life from a CR2032 coin cell in step-counter use cases. The 10-bit ADC captures heart-rate or SpO2 analog front-end signals, and the I2C peripheral interfaces to miniature OLED displays. The 28-UQFN EP package's 4x4mm footprint is among the smallest PIC16 options for ultra-compact wearable PCBs.
Recommended
LED Lighting Controller
The PIC16LF1827T-I/MV serves as a compact LED controller for low-power architectural lighting, signage, and decorative RGB lighting applications. The PWM channels combined with the 16-bit timers provide smooth dimming curves without flicker, while the I2C peripheral interfaces to addressable LED driver ICs like the TLC59116 or TLC5947 for multi-channel LED driving. The wide 1.8V-3.6V VDD range allows the MCU to operate directly from a 3.3V regulated supply downstream of a mains LED driver. The nanoWatt XLP sleep current keeps standby power consumption negligible in always-connected lighting fixtures.

Design Notes
Decoupling: place a 0.1uF ceramic capacitor within 5mm of the VDD pin (pin 9) and a second 0.1uF on the EPAD ground connection. For designs that switch the internal 32MHz oscillator on/off via OSCCON, add a 1uF bulk decoupling capacitor on VDD to suppress voltage transients when waking from sleep. The UQFN EP package requires the exposed pad to be soldered to a VSS copper pour with at least 4 thermal vias for proper thermal and electrical performance.
Battery life optimization: for coin-cell applications, configure IDLEN=0 and configure the deepest sleep mode (SLEEP via SLPEN) and use WDT or INT-on-pin to wake. Estimated: a 1% duty cycle at 32MHz active current of 4 mA and 100 nA sleep current yields average current of approximately 40 uA, giving roughly 220mAh/40uA = 5500 hours on a CR2032 - the XLP modes are essential to achieve multi-year battery life. Keep the C2OUT/C1OUT comparators powered down unless actively used.
Do not apply a voltage greater than 4.0V to any I/O pin on the LF (low-voltage F) variant; the absolute maximum on digital I/O is VDD + 0.3V. Programming voltage on MCLR/VPP (pin 26) must be limited to 9V absolute maximum per datasheet. Do not leave unused pins floating - configure them as outputs low or inputs with weak pull-ups via WPUA/WPUB registers to minimize sleep current leakage. The PIC16LF1827T-I/MV requires the XLP configuration bit cleared if your firmware was developed for the older non-XLP PIC16F1827 variant.
Place the 32kHz secondary oscillator crystal (if used) within 5mm of SOSCO/SOSCI (pins 18/19) and guard with a ground ring. For mTouch capacitive sensing, route the CPS pins (CPS0-CPS11) on the bottom layer only with no other traces within 0.5mm, and avoid ground fill beneath the touch pad area - this reduces parasitic capacitance and improves touch sensitivity. The CTMU module charges the touch pads at 18uA nominal, so power-supply noise directly couples into touch readings.
Compliance Information
RoHS compliant per Microchip product page and distributor listings (DigiKey SKU 2202150). Industrial temperature grade (-40C to +85C); not AEC-Q100 qualified - choose PIC16F1827T-I/MV automotive variants (where available) for AEC-Q100 applications.
