PIC16LF1936-E/MV Overview
An 8-bit microcontroller (MCU) is a programmable embedded processor that integrates CPU core, Flash program memory, SRAM, EEPROM, and peripherals onto a single silicon die. The PIC16F193x/LF193x family extends the classic PIC® RISC architecture into ultra-low-power applications by adding nanoWatt XLP technology, putting the device into sub-uA sleep states while retaining peripheral operation. This hierarchy - 8-bit MCU -> microcontroller -> embedded processor -> semiconductor - makes the part an ideal choice for battery-powered, display-driven products.
Key features include 14 KB of self-programmable Flash program memory, 256 bytes of EEPROM, 1024 bytes of SRAM, a 32 MHz internal oscillator, an integrated LCD controller with up to 96 segments, a 10-bit ADC, multiple timers, and enhanced PWM/capture/compare modules. Peripherals include EUSART, MSSP (SPI/I2C), and a Capacitive Sensing Module (CSM). The nanoWatt XLP technology delivers typical sleep currents below 100 nA, vastly extending battery life in portable designs.
Internally, the device uses a 14-bit instruction word RISC pipeline with Harvard architecture, separate program and data buses, and a wide variety of interrupt sources. The integrated LCD controller handles bias generation, contrast control, and variable clocking so the MCU can drive segment LCDs without external components, simplifying design and BOM.
Typical applications include battery-powered consumer devices with LCD segment displays (thermostats, remote controls, glucose meters), home appliances with user interfaces, industrial sensor readouts, metering and instrumentation, IoT edge nodes, and capacitive touch user interfaces. Designers select this part whenever they need integrated LCD drive, low sleep current, and compact 28-pin UQFN form factor on a single 2.3-3.6V rail.
Key design considerations include decoupling the VDD pin with a 100 nF ceramic capacitor placed within 5 mm, using the exposed pad to dissipate heat in higher-frequency designs, and configuring the LCD charge pump for proper bias generation when fewer than 1/3 bias segments are unused. Always program the configuration bits to match the WDT, BOR, and oscillator settings required for the application.

Typical Applications
PIC16LF1936-E/MV is suitable for 7 applications: Battery-Powered Thermostat with LCD Display, Wireless IoT Sensor Node with LCD Readout, Industrial Metering (Water/Gas/Energy) Front Panel, Capacitive Touch User Interface (Kitchen Appliance), Medical Handheld Device (Glucose / SpO2 Meter), Automotive Dashboard LCD Module, Consumer Remote Control with Status LCD.
Battery-Powered Thermostat with LCD Display
The PIC16LF1936-E/MV is a strong fit for battery-powered thermostats because its integrated LCD controller can drive up to 96 segments without an external driver, and its nanoWatt XLP technology delivers typical sleep currents below 100 nA per Microchip datasheet DS41364E. The 28-pin UQFN 4x4 mm package leaves ample PCB area for a coin-cell holder and the segment LCD glass. Engineers benefit from the part's 2.3-3.6 V direct compatibility with two-cell alkaline or single-cell lithium chemistries, removing the need for a boost converter. The integrated 10-bit ADC reads temperature sensors such as NTC thermistors at up to 100 ksps.
Recommended
Wireless IoT Sensor Node with LCD Readout
In a remote IoT sensor node, the PIC16LF1936-E/MV serves as the application MCU host for an RF transceiver (e.g., MRF24J40 or LoRa module), waking periodically to sample sensors and update a local segment LCD before returning to sleep. The 32 MHz core executes sensor fusion and basic encryption within the wake window, while XLP sleep currents below 1.5 uA (LCD enabled) preserve battery life across multi-year deployments. Per Microchip datasheet DS41364E, the EUSART and MSSP peripherals directly interface with common sub-GHz transceivers without external glue logic.
Recommended
Industrial Metering (Water/Gas/Energy) Front Panel
The integrated LCD controller of the PIC16LF1936-E/MV eliminates external driver chips in metering front panels that need to display cumulative consumption, units, status icons, and battery condition. The 32 MHz core runs metering algorithms at 100 ksps ADC rates while the part's -40 C to +125 C industrial-grade temperature range accommodates outdoor meter installations. According to Microchip documentation, the LCD charge pump supports bias generation at low VDD, keeping the contrast stable as the battery discharges.
Recommended
Capacitive Touch User Interface (Kitchen Appliance)
The PIC16LF1936-E/MV integrates the Capacitive Sensing Module (CSM), enabling touch-button or slider UIs on cooktops, ovens, and washing machines without dedicated touch ICs. The CTMU peripheral provides time-based touch measurements with high noise immunity, while the segment LCD shows mode and timer values. The 28-pin UQFN package is small enough to fit in tight control-panel cutouts. Per Microchip datasheet DS41364E, CSM hardware acceleration reduces CPU wake time and total average current relative to software-loop solutions.
Recommended
Medical Handheld Device (Glucose / SpO2 Meter)
Battery-powered medical handhelds such as blood-glucose monitors rely on the PIC16LF1936-E/MV for its low sleep current (<100 nA), small 4x4 mm UQFN package, and integrated LCD controller to show results on a custom segment display. The MCU's 14 KB Flash accommodates calibrated lookup tables for the disposable test strips, and the 10-bit ADC reads the photo/electrochemical sensor output. Microchip's medical-grade MPLAB X toolchain supports IEC 62304/ISO 14971 documentation workflows often required for FDA 510(k) submissions.
Recommended
Automotive Dashboard LCD Module
Inside an automotive cluster or HVAC control module, the PIC16LF1936-E/MV drives a segmented LCD while running keypad scanning, PWM backlight dimming, and CAN-bus message routing via the EUSART plus an external MCP2515 CAN controller. The E temperature grade (-40C to +125C) is qualified for cabin environments, and the PIC16LF1936-E/MV's QFN exposed pad supports the thermal dissipation needed under sustained MCU activity. Note that for under-hood AEC-Q100 applications, designers should select the PIC16F1937-E/MV automotive-grade variant.
Recommended
Consumer Remote Control with Status LCD
Universal remote controls and ceiling-fan controllers benefit from the PIC16LF1936-E/MV's integrated segment LCD to display channel, temperature, or fan-speed settings. The 32 MHz CPU executes NEC/RC5/RC6 IR decoding while timers capture incoming pulses at microsecond resolution. Sleep current below 1.5 uA with the LCD active enables multi-year operation from two AAA cells. Per Microchip documentation, the MSSP peripheral can drive a small I2C-controlled backlight LED controller directly.

Design Notes
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin, in parallel with a 1-10 uF bulk capacitor on the same node. For battery applications using the nanoWatt XLP modes, ensure the BOR (Brown-Out Reset) level is configured appropriately to avoid MCU resets as the battery discharges below 2.3 V. Use the internal LFINTOSC for low-power sleep transitions rather than external crystals, which draw additional current. Reference Microchip AN1267 for nanoWatt XLP tuning.
The 28-pin UQFN package has an exposed thermal pad that must be soldered to a PCB thermal land of at least equal size, with thermal vias to inner copper pours. Although the PIC16LF1936 is a low-power CMOS MCU, sustained 32 MHz operation with all peripherals active can dissipate noticeable heat in sealed enclosures. At 32 MHz CPU clock with all peripherals ON, estimated: theta_JA for 4-layer UQFN-28 with thermal vias is approximately 30 C/W; an ambient temperature of 85 C yields a junction rise of around 12 C, well within the 125 C limit. Designers should still validate thermal headroom in their specific board.
The UQFN 4x4 mm package with 0.4 mm pitch requires PCB land patterns per IPC-7351 and tight reflow profile control. Use ENIG or OSP surface finishes to prevent pad oxidation. Pin 1 is typically identified by the dot on the package top and the chamfered thermal pad; ensure PCB silk-screen markers match. For noise-sensitive applications, route the LCD segment lines away from the crystal traces to avoid capacitive coupling.
Do not skip the configuration-word setup: the WDT, BOR, and oscillator configuration bits must be programmed before code execution begins, otherwise the MCU may fail to start. For the integrated LCD, the COM and SEG pins must be assigned and the bias resistor ladder network properly connected; missing connections result in faint or unreadable display contrast. When migrating from PIC16LF1933 to PIC16LF1936, check that code targeting the larger Flash range does not exceed 14 KB or rely on unimplemented peripherals.
Compliance Information
RoHS and REACH compliant per Microchip product page. The E suffix denotes the industrial temperature grade (-40 C to +125 C), but this part is not AEC-Q100 qualified; for automotive applications choose the PIC16F1937-E/MV AEC-Q100 variant per Microchip ordering nomenclature.
