PIC16F1936-I/MV Overview
A PIC microcontroller (MCU) is a Harvard-architecture RISC processor widely used in embedded systems for control, sensing, and human-machine interface tasks. The PIC16F1936 belongs to the enhanced mid-range PIC16 family and adds an on-chip segmented LCD driver, making it a specialized member of the broader 8-bit MCU hierarchy that sits between simple PIC10/12/16 baseline parts and higher-end PIC18/dsPIC devices.
Key features include 14KB Flash program memory, 512 bytes of RAM, 256 bytes of EEPROM, 25 digital I/O pins, an internal 32 MHz oscillator, a 10-bit ADC with up to 14 channels, multiple timers (Timer0/1/2/4/6), enhanced PWM, MSSP (SPI/I2C), EUSART, and the integrated LCD driver supporting up to 96 segments. nanoWatt XLP technology delivers deep-sleep currents in the nanoamp range, making the part attractive for battery-powered products that must wake periodically to read sensors.
The architecture combines a single-cycle 8-bit ALU with a 14-bit instruction word, providing deterministic execution and tight code density. The integrated LCD controller can directly drive static, 1/2, 1/3, or 1/4 duty multiplexed glass, eliminating the need for an external LCD driver IC and reducing BOM cost in meter, appliance, and instrument designs.
Typical applications include battery-powered consumer products with LCD displays (thermometers, kitchen scales, remote controls), IoT sensor nodes that must sip power between transmissions, industrial HMI panels, metering equipment, and low-cost white goods with segmented LCD user interfaces.
When designing with this device, pay attention to the UQFN EP package's exposed pad - it must be soldered to the ground plane for both electrical grounding and thermal dissipation. Use Microchip's MPLAB X IDE with XC8 compiler for code development and consider the PICkit or ICD programmer for in-circuit debugging.

Typical Applications
PIC16F1936-I/MV is suitable for 6 applications: Battery-Powered Metering with Segmented LCD, Consumer Appliance HMI Panels, Battery-Powered IoT Sensor Nodes, Automotive Interior HMI and Lighting, Industrial Control and Monitoring, Portable Medical and Wellness Devices.
Battery-Powered Metering with Segmented LCD
The PIC16F1936-I/MV's integrated LCD driver supports up to 96 segments of static or multiplexed glass, removing the need for an external LCD controller and reducing BOM cost. Its nanoWatt XLP sleep current below 100 nA lets a battery-powered water, gas, or electricity meter sleep for years on a single lithium cell while periodically waking on RTCC overflow to update the display. The 14 KB Flash holds the metering firmware and LCD digit maps; the 10-bit ADC samples the sensor front-end with adequate resolution for class-1 metering. Operating voltage spans 2.3-5.5 V, accepting both single-AA and 3 V coin-cell stacks without level translation. The 28-UQFN EP package is small enough to fit inside a meter's housing, and the exposed pad dissipates heat during sustained ADC conversions. Designers should follow Microchip application note AN1606 for layout of the LCD bias network and use Microchip's MPLAB Code Configurator to generate the LCD segment map.

Consumer Appliance HMI Panels
Coffee machines, microwaves, washing machines, and air conditioners benefit from the PIC16F1936-I/MV's combination of LCD segment driver, 32 MHz CPU, and rich peripheral set including PWM, EUSART, and MSSP for I2C sensors. The 25 I/O pins accommodate keypad scanning, buzzer drive, relay control, and triac firing without an external I/O expander. nanoWatt XLP idle mode keeps standby power under regulatory limits for white goods - critical for meeting EU ERP and US ENERGY STAR requirements. The 28-UQFN EP footprint is compact enough for the tight PCBs found behind membrane keypads, and the exposed pad provides thermal relief when driving inductive loads. Designers should consult Microchip's TB3147 for noise-immune triac zero-cross detection patterns and pair the MCU with an MCP8024 gate driver for compressor or pump control.
Recommended
Battery-Powered IoT Sensor Nodes
The PIC16F1936-I/MV's nanoWatt XLP sleep current below 100 nA makes it a strong fit for remote sensor nodes that wake every few seconds to read a sensor, transmit, and return to sleep. The integrated 10-bit ADC digitizes thermistor, photocell, or soil-moisture probes directly, while the MSSP peripheral talks to I2C sensors such as the Bosch BMP280 or Sensirion SHT31. The 14 KB Flash comfortably holds state machines, Modbus frames, or LoRaWAN AT commands; the 256-byte EEPROM stores calibration constants and node IDs. The 2.3-5.5 V supply range accommodates both 3 V lithium primaries and rechargeable Li-ion packs. The 28-UQFN EP package is small enough to fit inside AA-battery-powered enclosures. Engineers should use Microchip's TB3118 application note for low-power design patterns and enable the RTCC periodic wake-up to minimize active duty cycle.

Automotive Interior HMI and Lighting
The PIC16F1936-E/MV (extended temperature grade, -40C to +125C) handles automotive interior HMI such as climate-control displays, mirror controls, and ambient lighting, where the integrated LCD driver and multiple PWM channels can drive both the segmented display and a string of RGB LEDs. The 25 I/O pins are sufficient for key-scanning and LIN or CAN-ready UART connectivity, while the EUSART block talks to a system-on-chip gateway over LIN. AEC-Q100 qualification of the underlying silicon family (check specific lot) makes the part suitable for cabin electronics, though body controller modules typically require a Q-graded part number. The 28-UQFN EP package passes automotive vibration profiles when soldered with adequate corner staking. Designers should review Microchip's automotive reference designs on the MPLAB Xpress page.
Recommended
Industrial Control and Monitoring
In industrial control panels, the PIC16F1936-I/MV serves as the local HMI controller: the integrated LCD shows process variables while the 10-bit ADC reads 4-20 mA loop currents via a burden resistor, and the EUSART links to a PLC or Modbus RTU master. The 32 MHz CPU executes PID loops and alarm logic in real time. The 25 I/O pins handle push-button input, status LEDs, and SSR or relay drive. The 256-byte EEPROM retains setpoints through power cycles, eliminating backup-battery circuits. The 2.3-5.5 V supply accepts 24 V industrial rails after a step-down regulator such as the LM2596 or MCP16311. The 28-UQFN EP package fits inside the tight enclosures of DIN-rail mount modules.
Recommended
Portable Medical and Wellness Devices
Blood-pressure monitors, glucose meters, digital thermometers, and pulse oximeters benefit from the PIC16F1936-I/MV's combination of LCD segment driver, low-power sleep, and on-chip ADC. The integrated LCD shows readings on a segmented glass without a separate controller; the 10-bit ADC reads thermistor or pulse-oximetry photodiode signals; and the nanoWatt XLP sleep current preserves battery life between uses. The 256-byte EEPROM stores calibration and last-reading data. The 2.3-5.5 V supply accepts two AAA cells directly. The 28-UQFN EP package fits inside handheld enclosures. Designers should follow IEC 60601-1 EMI mitigation guidance and use Microchip's TB3018 for medical-device firmware validation patterns.

- Extended temperature grade for automotive interiors (vs PIC16F1936-E/MV)
Design Notes
The 28-UQFN EP package has an exposed thermal pad on the underside that MUST be soldered to a ground copper pour of at least 0.5 in^2 for both electrical grounding and thermal dissipation. Place a 0.1 uF decoupling capacitor within 2 mm of each VDD/VCAP pin. Avoid routing signal traces under the UQFN package body where the EP would block them; instead, route the inner layers to the perimeter. The exposed pad improves thermal performance by approximately 30 C/W versus a non-EP QFN of the same size, critical when the LCD charge pump and ADC operate continuously.
To achieve the nanoWatt XLP sleep current below 100 nA typical, disable all unused peripherals before entering Sleep, switch the system clock to the low-power LFINTOSC, and avoid floating digital inputs (which can supply leakage currents). Use the WDT with its separate 32 kHz source only when periodic wake-up is needed; otherwise disable the WDT for the deepest sleep. Designers should refer to Microchip TB3118 for low-power design patterns and TB3147 for noise-immune resets. Bulk decoupling of 10 uF + 100 nF on the VDD rail is recommended for ADC accuracy.
Route the LCD segment and common lines away from the digital switching traces and the switching power supply to avoid ghosting and contrast drift. Use guard traces or ground pours between the LCD bus and noise sources. Tie unused I/O pins to defined logic levels (VDD or VSS) - never leave them floating - to minimize sleep-mode leakage. For the VCAP pins that bypass the internal voltage regulator, use ceramic capacitors of at least 0.1 uF placed as close to the pins as possible; larger values (1 uF) improve LCD contrast stability.
Do not exceed 5.5 V on any VDD pin; absolute maximum ratings include ESD stress and supply transients that can latch up the part. The MCLR/RE3 pin has an internal pull-up; if unused, leave it open or connect to VDD through a 10 kohm resistor. Programming via ICSP requires the ICSPCLK, ICSPDAT, MCLR, VDD, and VSS lines accessible - provide a 5-pin header or Tag-Connect pads for in-circuit debugging. The LCD bias pins (VLCD1-3) must be properly configured in the LCDCON register before the LCD segment lines will display correctly - a common initialization error on first-time designs.
Compliance Information
RoHS and lead-free compliant per Microchip product page and DigiKey listing. Not AEC-Q100 qualified - choose PIC16F1936-E/MV for extended temperature range; AEC-Q100 automotive qualification requires a specific -Q part number not in this case.
