PIC16F1936T-I/ML Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data RAM, EEPROM, peripherals (timers, ADC, communication, I/O), and interrupt logic onto one die. The PIC16F core uses a modified Harvard RISC architecture with a 14-bit instruction word and a two-stage pipeline, optimized for deterministic response and low interrupt latency. The PIC16F1936 sits within the XLP (eXtreme Low Power) family, where nanoWatt technology enables sleep currents below 50 nA, supporting battery-powered applications that demand years of standby life.
Key features include 512B RAM, 256B EEPROM, an on-chip LCD driver capable of driving up to 64 segments, a 5-channel 10-bit ADC, multiple timers (Timer0/1/2/6), EUSART, I2C, SPI, and up to 25 digital I/O pins. Internal 16 MHz and 32 kHz oscillators reduce external component count. The integrated LCD charge pump and on-chip voltage reference minimize external BOM for glass and chip-on-board displays.
The PIC16F1936 architecture uses CMOS flash technology with 100,000 erase/write endurance on the program memory and 1,000,000-cycle EEPROM endurance. Enhanced peripherals include mTouch capacitive sensing, an SR-latch, PWM modules, and a configurable logic cell. Together they provide flexibility for mixed-signal front-ends in a single MCU.
Typical applications include battery-powered consumer devices with segment LCDs (thermostats, blood pressure monitors, water/gas meters), home appliances with user interfaces, industrial control panels, and remote sensor nodes. The XLP sleep current is critical for metering and IoT edge nodes powered by coin-cell or 2x AA cells.
Design consideration: route the QFN-28 (6x6 mm) thermal/exposed pad (EP) to a continuous ground copper pour to dissipate up to ~800 mW and to meet the -40C to +85C industrial range under sealed-enclosure conditions. Enable the internal oscillator to save two external crystals and reduce BOM.

Typical Applications
PIC16F1936T-I/ML is suitable for 7 applications: Battery-Powered Thermostat with LCD, Residential Gas and Water Meter, White Goods Control Panel (Washing Machine / Dishwasher), Blood Pressure / Glucose Meter (Consumer Medical), Industrial Sensor Transmitter (4-20 mA / WirelessHART), Remote Control with LCD Status Bar, IoT Edge Node with Segment LCD HMI.
Battery-Powered Thermostat with LCD
The PIC16F1936T-I/ML fits battery-powered thermostats thanks to its integrated 64-segment LCD driver and <50 nA typical XLP sleep current. The 14 KB Flash accommodates HVAC state machines, weekly schedules, and PID loops; the 10-bit ADC reads NTC thermistors with 0.1 C resolution after averaging. A 32.768 kHz external crystal enables RTC for time-based scheduling while the main core sleeps. 2x AA cells can deliver 5+ years of standby life under typical duty cycles. The QFN-28 (6x6 mm) footprint supports compact wall-mount enclosures behind the glass LCD.
Recommended
Residential Gas and Water Meter
For residential utility meters, the PIC16F1936T-I/ML combines LCD segment driving, eXtreme Low Power (nanoWatt XLP) for 10+ year coin-cell life, and on-chip EEPROM for tamper-resistant consumption logs. The 11-channel 10-bit ADC digitizes flow-sensor pulses and battery voltage; UART/I2C/SPI connect to wireless M-Bus or LoRaWAN modules. The 25 I/O drive tamper switches, valve control, and the optical interface per IEC 62056-21. Industrial -40 C to +85 C operation handles outdoor enclosures. QFN-28 (6x6 mm) keeps the BOM compact for in-line meter designs.
Recommended
White Goods Control Panel (Washing Machine / Dishwasher)
In washing machine or dishwasher control panels, the PIC16F1936T-I/ML drives the segment LCD that shows cycle, temperature, and time remaining. The 32 MHz core executes motor-control supervisory logic with deterministic interrupt response for triac zero-cross timing. The 10-bit ADC reads temperature sensors (NTC), water level, and motor current; PWM modules dim LED indicators. The integrated charge pump drives the LCD at 5 V without external boost components, reducing BOM cost by ~$0.40 vs discrete LCD bias circuits. The QFN-28 footprint survives vibration in laundry appliances.
Recommended
Blood Pressure / Glucose Meter (Consumer Medical)
Consumer medical devices such as wrist blood pressure monitors and blood glucose meters use the PIC16F1936T-I/ML to drive the segment LCD, inflate the cuff via PWM, and read the pressure sensor with the 10-bit ADC. The XLP sleep current below 50 nA extends 2x AAA battery life to 6+ months with daily measurements. 512 B RAM buffers measurement arrays; 256 B EEPROM stores calibration constants and last-30-day history. The integrated LCD charge pump eliminates the external -3 V bias inverter required by discrete drivers. Industrial -40 C to +85 C range supports storage and shipping stress.
Recommended
Industrial Sensor Transmitter (4-20 mA / WirelessHART)
Industrial loop-powered sensor transmitters leverage the PIC16F1936T-I/ML's industrial -40 C to +85 C range, integrated ADC, and low XLP sleep current. The 10-bit ADC digitizes pressure, temperature, or flow transducers; the EUSART drives a 4-20 mA DAC or a WirelessHART/WirelessHART modem. The 14 KB Flash holds linearization curves (PT100/PT1000 lookup tables) and HART command stacks. EEPROM stores calibration certificates and HART long-tag data. The QFN-28 (6x6 mm) footprint suits 1-inch-diameter field-mount enclosures.
Recommended
Remote Control with LCD Status Bar
Universal remote controls and AV receivers with segment-LCD status bars benefit from the PIC16F1936T-I/ML's 14 KB Flash (IR protocol database), 32 MHz MIPS (real-time IR modulation/demodulation), and integrated LCD driver for 32-64 segment displays. The 25 I/O drive keypad matrix scan, IR LED, and rotary encoder. nanoWatt XLP sleep current <50 nA extends AAA battery life to 12+ months in standby. The QFN-28 (6x6 mm) footprint enables slim 8 mm remote housings. UART enables firmware updates and factory test.
Recommended
IoT Edge Node with Segment LCD HMI
Battery-powered IoT edge nodes with a small segment LCD HMI (e.g., LoRaWAN soil-moisture, asset-tracking, smart-locks) use the PIC16F1936T-I/ML as the application processor. The 32 MHz core runs LoRaWAN MAC stacks and sensor-fusion routines; the LCD displays status, RSSI, and battery level locally. The XLP nanoWatt sleep mode (<50 nA) is critical for multi-year coin-cell deployments. EUSART interfaces to the LoRa/BLE modem; the ADC digitizes sensors; SPI drives an external flash for logging. QFN-28 (6x6 mm) supports IP67 enclosures.

Design Notes
Solder the QFN-28 (6x6 mm) exposed pad (EP, pin 29) to a continuous ground copper pour of at least 50 mm^2 to keep junction temperature within the -40 C to +85 C industrial range. The die dissipates up to ~800 mW under full peripheral load (LCD + ADC + EUSART active). Without the EP soldered, the thermal resistance theta_JA exceeds 70 C/W, violating industrial temperature limits at >200 mW. For sealed enclosures (IP65+) add a thermal via array under the EP and route heat to inner copper layers.
Decouple VDD (pin 8) with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin, plus a bulk 1 uF to 10 uF tantalum or ceramic on the same net. Place the 100 nF cap on the same layer as the IC to minimize loop inductance. For battery applications, add a 100 kohm resistor from VDD to the MCLR/VPP pin to limit current during brown-out. The XLP sleep current (<50 nA typical) is only achieved with all peripherals off and the internal LF oscillator running; verify the WPUE bit configuration to avoid floating-input leakage.
Do not omit the ICDSP/ICSP connector for PICkit programming: RB6 (ICSPCLK, pin 18) and RB7 (ICSPDAT, pin 17) must be reachable for in-circuit serial programming. The MCLR/VPP pin (pin 27) needs a 10 kohm pull-up to VDD for normal operation and a capacitor to ground to filter programming voltage spikes. For low-power designs, route the LCD charge-pump capacitors (VLCD, VLCD2, VLCD3) per datasheet and bypass the LCD bias reference with a 1 uF cap to avoid flicker on glass displays. The internal 16 MHz oscillator requires calibration via the OSCTUNE register after brown-out events.
Route the analog ADC inputs (AN0-AN11) away from digital switching lines (CCP PWM, oscillator) to avoid coupling noise into the 10-bit ADC. Use a ground guard ring around the analog traces tied to the analog ground (AGND) plane. Keep the LCD segment traces short and matched to minimize ghosting on the glass. Place the external 32.768 kHz crystal within 5 mm of pins 1-2 (RA4/RA5 on QFN-28) with grounded guard traces to suppress stray capacitance that detunes the RTC oscillator. Connect the EP to a 4-via thermal array to inner ground plane.
