PIC16LF1936-I/SS Overview
What is a PIC16 microcontroller? A PIC16 microcontroller is an 8-bit RISC-based CMOS MCU from Microchip that belongs to the broader family of microcontrollers -> microcontrollers -> semiconductor ICs. The PIC16LF1936 specifically is part of the enhanced mid-range PIC16F/LF193x lineup that adds capacitive touch support via the mTouch™ sensing solution and the proprietary nanoWatt XLP™ technology for ultra-low-power operation, ideal for battery-powered applications where quiescent current can drop into the sub-µA range.
Key features include 36 I/O pins, a 10-bit ADC with up to 17 channels, two comparators, four 8-bit timers plus one 16-bit timer, an EUSART and two MSSP (I²C/SPI) modules, and the integrated LCD driver. The XLP nanoWatt technology delivers typical sleep currents below 50 nA with full RAM retention, enabling multi-year battery life in applications such as thermostats, metering, and remote sensor nodes.
The enhanced mid-range core provides 49 instructions, a 14-bit instruction word, a hardware stack with 16 levels, and direct interrupt-on-change handling on all I/O pins. The integrated LCD module supports static, 1/2, 1/3, and 1/4 duty cycles with a charge pump option for low-voltage glass, while the mTouch peripheral enables capacitive touch buttons, sliders, and proximity sensing without external components.
Typical applications include battery-powered consumer devices with segment LCDs, home-automation sensor hubs, industrial gauges, thermostat controls, medical dosing pumps, and IoT edge nodes. The wide 1.8V-3.6V operating window also suits 2xAA / coin-cell powered designs where boost converters are undesirable.
When designing with the PIC16LF1936-I/SS, ensure that VDD decoupling uses a 100nF ceramic capacitor placed within 5mm of the VDD pin, that the MCLR pin is pulled up through a 10kΩ resistor, and that the internal oscillator calibration value is committed to the MCU's calibration register on first programming to maintain 32MHz accuracy across the full temperature range.

Typical Applications
PIC16LF1936-I/SS is suitable for 6 applications: Battery-Powered Thermostat Control, Industrial Gas Meter with LCD, Consumer Remote Control with Segment LCD, Medical Dosing Pump Controller, Home-Automation Sensor Hub, IoT Edge Node with Coin Cell.
Battery-Powered Thermostat Control
The PIC16LF1936-I/SS is a strong fit for battery-powered thermostats thanks to its nanoWatt XLP technology, which delivers sleep currents below 50 nA with full RAM retention. With the integrated LCD driver supporting up to 96 segments, the MCU can directly drive a 4-digit plus icon glass without an external segment driver. The 14 KB Flash holds typical thermostat state machines including hysteresis, scheduling, and setpoint storage. At 32 MHz active the core draws about 2 mA, so on 2xAA batteries a duty-cycled design achieves multi-year life.
Recommended
Industrial Gas Meter with LCD
For industrial gas meters the PIC16LF1936-I/SS combines the integrated 96-segment LCD driver for direct 7-segment numeric and annunciator drive, a 10-bit ADC for temperature compensation of the flow sensor, and EUSART for AMR (automated meter reading) uplink. The 1.8-3.6 V supply range lets the design run directly from a single lithium primary cell, eliminating boost losses. nanoWatt XLP keeps the average current below 30 µA in 1-second polling duty, enabling 10+ year battery life in sealed metering applications.
Recommended
Consumer Remote Control with Segment LCD
The PIC16LF1936-I/SS suits premium AV remote controls that need a status LCD showing channel, volume, and battery indicators. The 36 I/O pins are ample for matrix keypads, IR emitter drive, and capacitive touch sliders, while the 14 KB Flash holds advanced remote control state machines, NEC/RC5/RC6 protocol libraries, and pairing logic. The integrated LCD driver eliminates the need for an external HT1621 or equivalent segment driver, reducing BOM cost and PCB area in small handheld enclosures.
Recommended
Medical Dosing Pump Controller
For medical dosing pumps, the PIC16LF1936-I/SS provides the EEPROM for storing calibration constants and dosing profiles, the 10-bit ADC for sensing pump motor current feedback, and the integrated LCD for displaying infusion parameters. The enhanced mid-range core executes PID motor control loops well within the 200 ns instruction budget at 32 MHz. nanoWatt XLP keeps standby current under 1 µA, critical for battery-backed patient mobility, while the 36 I/O pins handle stepper drivers and alarm buzzer outputs.
Recommended
Home-Automation Sensor Hub
In a home-automation sensor hub, the PIC16LF1936-I/SS aggregates signals from a door sensor, PIR motion detector, temperature sensor, and a humidity sensor, then communicates via UART or SPI to a master gateway. The two MSSP peripherals let the MCU talk to an SPI sensor and an I²C sensor simultaneously, while the EUSART handles the wireless module link. The 14 KB Flash is sufficient for protocol translation and on-device sensor fusion, and the small 28-SSOP package fits inside the sensor housing on the wall.
Recommended
IoT Edge Node with Coin Cell
For coin-cell IoT edge nodes, the PIC16LF1936-I/SS offers the lowest sleep current in the 28-SSOP PIC16 family thanks to nanoWatt XLP. With a CR2032 coin cell providing 3 V, the device can wake periodically, sample sensors through the 10-bit ADC, transmit via the EUSART, and return to sleep below 50 nA. The on-chip EEPROM allows persistent configuration storage across power cycles, and the 14 KB Flash holds firmware update images, BLE command stacks, and small protocol parsers typical of LPWAN or BLE sensor nodes.

Key Differentiators
- Integrated 96-segment LCD driver without external segment IC (vs PIC16LF1826-I/P)
- nanoWatt XLP sleep below 50 nA with full RAM retention (vs PIC16LF1903-I/SP)
- 14 KB Flash with 36 I/O in 28-SSOP (vs PIC16LF1933-I/SS)
Design Notes
Estimated: with VDD = 3.0 V and CPU idle in sleep, the PIC16LF1936-I/SS draws approximately 50 nA when Sleep mode is enabled and peripherals are gated. Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the VDD pins and a 10 µF bulk cap near the IC for transient response during LCD charge-pump cycles. Wake from sleep can be triggered by INT, IOC, WDT, or RTC interrupt sources without external wake circuitry.
Route the MCLR pin through a 10 kΩ pull-up to VDD and avoid routing noisy digital lines near the LCD segment pins. Place the optional LCD bias capacitors directly at the COM and SEG pads to minimize segment ghosting. For mTouch capacitive sensing, dedicate one unused I/O as a guard ring around touch electrodes and avoid copper pours directly beneath the touch pads to preserve sensitivity.
Do not exceed 3.6 V on VDD - this is the 'LF' low-voltage variant, not the 'F' 5.5 V variant. Ensure the CONFIG register's oscillator selection matches the hardware configuration; using an external crystal without setting the FOSC bits correctly causes the device to appear dead on power-up. The ICD/ICSP programming pins (RB6/ICSPCLK and RB7/ICSPDAT) should be left in their default configuration or have weak pull-ups to avoid blocking debug access.
When using the EUSART at higher baud rates (above 115 200 baud at 32 MHz), keep the TX/RX traces short and add a series resistor of 22-33 Ω to dampen reflections on long cables. For SPI master mode running above 8 MHz, keep traces matched within 5 mm and provide a ground reference directly under the bus. The MSSP I²C bus needs 4.7 kΩ pull-ups on both SDA and SCL for standard-mode 100 kHz operation; switch to 2.2 kΩ for fast-mode 400 kHz.
Compliance Information
