PIC16F1936T-I/MV Обзор
An 8-bit microcontroller (MCU) is a compact, single-chip processor with an 8-bit data bus, typically integrating CPU, Flash program memory, SRAM data memory, EEPROM, timers, ADC, comparators, and serial peripherals into one package. Within the broader taxonomy, an MCU belongs to microcontrollers → integrated circuits (ICs) → semiconductors. The "PIC16" prefix designates Microchip's mid-range enhanced 8-bit core family, widely used in cost-sensitive and battery-powered embedded designs.
Key features include an integrated LCD driver supporting up to 96 segments, three timers (Timer0/Timer1/Timer2), two comparators, a 5-bit DAC, EUSART, MSSP (I²C/SPI), 25 digital I/O pins, and 11 capacitive-touch channels via the mTouch™ peripheral. The nanoWatt XLP™ technology enables extended battery life across the 2.3 V to 5.5 V operating range. The UQFN-28 (MV) package has an exposed thermal pad, lowering θJA versus standard QFN and improving continuous high-current operation.
Architecturally, the device uses the PIC16 enhanced mid-range core with a single-cycle instruction execution model (except branches) and a 16-level hardware stack. This RISC-style architecture simplifies deterministic timing analysis and code generation, while on-chip peripherals are mapped to linear memory to keep C-compiler output efficient.
Typical applications include battery-powered IoT sensor nodes, low-power LCD-display consumer products, capacitive-touch user interfaces, household appliances, and industrial control panels. The wide 2.3 V to 5.5 V supply range makes it drop-in compatible with 2 × AA, 2 × AAA, single-cell Li-ion, and 5 V regulated rails.
Designers should reserve the exposed pad for thermal relief and provide 0.1 µF decoupling on VDD/VSS pairs within 2 mm of the pins. For low-power battery designs, follow Microchip application note AN1267 on nanoWatt XLP™ sleep-current optimization. The PIC16F1936T-I/MV uses the T suffix to indicate tape-and-reel packaging.

Типичное применение
PIC16F1936T-I/MV подходит для 6 применениеs: Battery-Powered IoT Sensor Node, Low-Power LCD Appliance Front Panel, Capacitive-Touch User Interface, Industrial Sensor Transmitter (4-20 mA Loop), Home Automation Sensor Hub, Portable Medical Monitoring Accessory.
Battery-Powered IoT Sensor Node
The PIC16F1936T-I/MV's nanoWatt XLP™ technology and deep-sleep current below 50 nA make it a strong fit for battery-powered IoT sensor nodes transmitting temperature, humidity, or occupancy data every few minutes. The 32 MHz core handles sensor acquisition and EUSART/MSSP transmit bursts within milliseconds, then returns to sleep, while the 14 KB Flash supports Over-The-Air (OTA) bootloaders and the 256-byte EEPROM stores calibration constants. Estimated average current of 5 µA at 2 × AA yields a service life exceeding 5 years; the 2.3 V–5.5 V range accepts fresh and end-of-life alkaline chemistries without external boost.

Low-Power LCD Appliance Front Panel
The on-chip LCD driver supporting up to 96 segments allows the PIC16F1936T-I/MV to drive a 4-mux × 24-segment LCD directly, eliminating an external LCD controller in washing machines, microwave ovens, and thermostats. With charge-pump-based LCD bias generation, the display persists in deep-sleep without CPU intervention, drawing under 1 µA. The 25 GPIOs handle capacitive touch buttons, rotary encoders, and LED indicators. The 28-UQFN (4 × 4 mm) exposed-pad package fits tight front-panel enclosures and offers a θJA suitable for sustained operation up to 85 °C.
Рекомендуется
Capacitive-Touch User Interface
The PIC16F1936T-I/MV integrates Microchip's mTouch™ CTMU peripheral supporting up to 11 capacitive-touch channels, enabling slide-and-button interfaces without a dedicated touch controller. The 10-bit ADC and 2 comparators add proximity and water-tolerance detection. Combined with the LCD driver, designers can build complete sealed-front-panel HMIs (human-machine interfaces) for medical, industrial, and consumer products. Acquisition and debounce fit easily within the 14 KB Flash budget; the exposed-pad UQFN-28 (4 × 4 mm) package provides thermal headroom for backlit LCD boost converters.
Рекомендуется
Industrial Sensor Transmitter (4-20 mA Loop)
In a 4-20 mA loop-powered transmitter, the PIC16F1936T-I/MV's 2.3 V minimum VDD and nanoWatt XLP™ sleep mode let the MCU run directly from the 4 mA loop with current budgets as low as 3.2 mA total. The 17-channel 10-bit ADC digitizes pressure, temperature, or flow sensors; the 5-bit DAC drives the loop current modulator; and the 256-byte EEPROM stores calibration and unit tags. Industrial -40 °C to +85 °C operation is supported. The UQFN-28 (4 × 4 mm) package with exposed pad fits standard field-mount housings.
Рекомендуется
Home Automation Sensor Hub
The PIC16F1936T-I/MV fits central-control hubs aggregating inputs from Zigbee, BLE, or sub-GHz wireless modules via EUSART and MSSP peripherals. The 32 MHz core handles protocol parsing and local decision logic, while 14 KB Flash supports multi-protocol stacks. The 25 GPIOs drive RGB indicators, buzzers, and relay outputs; the 10-bit ADC monitors rail voltages and battery levels. Low sleep current (~50 nA) extends backup-battery operation during grid outages. UQFN-28 (4 × 4 mm) keeps the PCB under 25 mm × 25 mm.

Portable Medical Monitoring Accessory
The PIC16F1936T-I/MV's deterministic PIC16 enhanced core and nanoWatt XLP™ technology suit portable medical accessories such as pulse-oximeter dongles and adherence monitors that demand long battery life and reliable real-time response. The 14 KB Flash supports a small RTOS or state-machine plus ML-feature extraction; 25 GPIOs interface to photodiode sensors, BLE radios, and OLED displays; and the 11 mTouch channels implement clean capacitive buttons. Operating at 3.0 V from a CR2032 coin cell with sleep duty-cycling, designers can target 6+ months of runtime in a 25 mm × 30 mm enclosure.

Заметки по проектированию
Estimated: to achieve < 1 µA average current in a periodic sensor-logging application, configure the PIC16F1936T-I/MV for Sleep mode with the WDT or RTCC as wake-up source. Disable all unused peripherals (ADC, comparators, EUSART, MSSP) and switch unused pins to output-low via the LATA/LATB/LATC registers. Use the LF-version PIC16LF1936T-I/MV if VDD drops below 2.3 V at end-of-battery life; otherwise the brown-out reset (BOR) will engage and inflate average current. Reference: Microchip application note AN1267, "Power Management for PIC16F1xxx".
Place 0.1 µF X7R 0402/0603 decoupling capacitors on every VDD/VSS pair within 2 mm of the pins. The UQFN-28 exposed pad (EP, pin 29) MUST be soldered to a continuous ground pour with at least 8 thermal vias (0.3 mm diameter, 0.5 mm pitch) to a bottom-layer ground plane to keep θJA low. For noise-sensitive analog applications, isolate the analog VDD rail (pin 10) with a ferrite bead from digital VDD, and place a 10 µF bulk capacitor near VCAP (pin 27) for the internal 1.8 V regulator. Reference: Microchip datasheet 41374D, section 3.0 "Guidelines for Getting Started with PIC16F1xxx".
Keep the 32 MHz crystal traces short (< 5 mm) and symmetric. Guard the crystal area with a ground ring tied to the EP ground pour; route digital signals away from OSC1/OSC2 (RA7/RA6) and the analog AVSS/AVDD pair (RA0-RA5, RB1-RB5, RC2-RC4). For mTouch™ designs, route CTMU channels on the opposite side of the board from switching power or high-frequency digital signals, and add a hatched ground shield under each touch pad to improve moisture immunity. Reference: Microchip application note AN1478, "mTouch™ Sensing Solution Acquisition Methods".
Do not forget the VCAP (pin 27) capacitor - the internal 1.8 V regulator requires at least 0.1 µF and will not start cleanly without it. Ensure the CONFIG1 register LVP (low-voltage programming) bit is enabled or a high-voltage programmer (ICD 3 / PICkit 4) is used for initial in-circuit programming. Configuring RA3 as a digital I/O without disabling the analog VREF+ function will cause the pin to behave unpredictably. Always set ANSEL/ANSELH bits to 0 for digital-only pins. Reference: Microchip datasheet 41374D, "Special Features of the CPU" section.
