PIC16F1936-E/MV 概要
An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data bus, integrating a CPU, Flash program memory, RAM, EEPROM, timers, ADC, and communication peripherals. The PIC16F1936 sits in the PIC16 mid-range family (PIC16 -> PIC mid-range -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor), using a RISC architecture with 49 instructions. The integrated LCD driver with charge pump supports up to 96 segments directly, eliminating the need for external LCD controller ICs in user-interface designs.
Key features include 14KB (8K x 14 words) self-programmable Flash, 256B EEPROM, 25 digital I/O pins, 11-channel 10-bit ADC, two 8-bit timers, one 16-bit timer, enhanced PWM, MSSP (SPI/I2C), EUSART, and a real-time clock with calendar. The nanoWatt XLP technology delivers typical sleep currents below 1 µA with full RAM retention and watchdog timer operation, making the device suitable for applications that spend most of their time in standby.
The PIC16F1936 implements a modified Harvard architecture with separate program and data buses, an 8-level hardware stack, and an instruction set optimized for C code generation through the XC8 compiler. The integrated mTouch capacitive-sensing peripheral and CTMU (Charge Time Measurement Unit) add touch-button and proximity-sensing capability without external components.
Typical applications include battery-powered consumer devices with LCD displays, home automation sensor nodes, automotive instrument clusters (PIC16F1936-I/MV industrial variant), medical glucose meters and portable monitors, IoT edge sensors with local display feedback, and low-cost white-goods user interfaces. The -E suffix denotes the Extended temperature grade (-40°C to +125°C), while /MV indicates the 28-pin UQFN-EP package.
When designing with this device, allocate one I/O pin per LCD segment above the integrated 4 commons x 24 segments baseline and verify charge-pump capacitor selection against the on-glass panel capacitance. Programming via ICSP requires RB6/ICCK and RB7/ICCDAT to remain accessible; avoid reassigning them to high-load outputs without a test-point footprint.

主な用途
PIC16F1936-E/MV の用途: 6 件s: Battery-Powered Consumer Devices with LCD, Home Automation Sensor Hubs, Automotive Instrument Clusters and HMI, Medical Glucose Meters and Portable Monitors, Industrial Sensor Nodes and IoT Edge Devices, White Goods and Appliance User Interfaces.
Battery-Powered Consumer Devices with LCD
The PIC16F1936-E/MV is ideally suited for battery-powered consumer products that integrate a segment LCD, such as digital thermometers, kitchen scales, remote controls with displays, and electronic blood-pressure monitors. Its integrated LCD driver supports up to 96 segments with internal charge pump, eliminating the need for an external negative-voltage LCD bias supply and saving BOM cost in compact handheld enclosures. The nanoWatt XLP sleep current near 50 nA extends coin-cell battery life to multi-year operation, while the 1.8-5.5V VDD range accommodates 2-cell alkaline, single-cell Li-ion, or USB-bus power sources with no additional LDO required.
おすすめ
Home Automation Sensor Hubs
In home automation sensor hubs and wall-mounted keypads, the PIC16F1936-E/MV drives the front-panel LCD, scans mTouch capacitive buttons via the CTMU peripheral, and reports status over UART or SPI to a host controller. The integrated 11-channel 10-bit ADC reads temperature, humidity, and ambient-light sensors directly, while the EUSART and MSSP peripherals provide flexible connectivity to wireless modules or downstream MCUs. With sleep current under 1 µA and fast wake-up from the 32 kHz Timer1 oscillator, the design can poll sensors every few seconds while still running for over a year on two AA batteries.
おすすめ
Automotive Instrument Clusters and HMI
The PIC16F1936-E/MV's Extended temperature grade (-40C to +125C) makes it suitable for automotive instrument cluster sub-assemblies, climate-control HMI panels, and aftermarket gauge displays. It drives the segment LCD for odometer, fuel, and temperature readouts while simultaneously sampling sensor inputs via the ADC and generating PWM outputs for backlight dimming or warning-buzzer tone generation. AEC-Q100 qualification is not held by this part, but automotive Tier-1 suppliers commonly qualify it per their internal standards for non-safety HMI sub-systems where full Q-100 parts are not mandated.
おすすめ
Medical Glucose Meters and Portable Monitors
Portable medical devices such as blood-glucose meters, pulse oximeters, and handheld spirometers benefit from the PIC16F1936-E/MV's small footprint (UQFN-28 4x4 mm), integrated LCD driver, and ultra-low sleep current. The MCU directly drives a 96-segment TN-glass display showing measurement results, battery status, and time/date without external components. The 14KB Flash accommodates application code plus a small RTOS or state-machine scheduler, while the 256B EEPROM stores calibration coefficients and last-100 reading history with 1M-cycle endurance.
おすすめ
Industrial Sensor Nodes and IoT Edge Devices
For industrial IoT edge sensor nodes (temperature, pressure, flow, gas detectors) the PIC16F1936-E/MV provides local measurement, on-device LCD read-out, and serial uplink to a gateway or PLC. The 11-channel 10-bit ADC and CTMU peripheral interface with thermocouples, RTDs, and 4-20 mA loops via external signal conditioning. The nanoWatt XLP technology keeps quiescent current below 1 µA, supporting energy-harvesting or battery-backed operation in remote locations, and the 25 I/O pins accommodate multiple sensor channels plus communication peripherals.
おすすめ
White Goods and Appliance User Interfaces
In white-goods user interfaces (washing-machine control panels, microwave ovens, dishwasher displays, refrigerator temperature readouts) the PIC16F1936-E/MV drives the segment LCD, scans the keypad matrix, controls buzzer/relay outputs, and modulates LED backlight via PWM. The 32 MHz core handles debounce, timer management, and serial communication to the main appliance controller, while the low-power modes minimize standby consumption to meet Energy Star requirements. The Extended temperature grade supports the elevated ambient inside appliance enclosures during operation.

主な差別化要因
- Integrated LCD driver with charge pump up to 96 segments （vs PIC16F1827)
- nanoWatt XLP sleep current of ~50 nA （vs PIC16F877A)
- Extended temperature grade -40C to +125C （vs PIC16F1936-I/MV)
設計ノート
Estimated: with VDD = 3.3V, CPU active at 32 MHz, and all peripherals enabled, the PIC16F1936-E/MV draws approximately 5 mA; in sleep mode with WDT disabled it drops to about 50 nA. Place a 100 nF decoupling capacitor within 3 mm of VDD (pin 7) and a bulk 10 µF tantalum or ceramic on the same net; connect VSS (pin 8) directly to the ground plane via a short trace or via-in-pad to keep digital switching noise out of the ADC reference.
The PIC16F1936-E/MV LCD driver requires an external charge-pump capacitor on the VCAP/SEG21 pin (pin 19); omitting this capacitor prevents the charge pump from starting and the LCD will not display. Per the Microchip datasheet, use a 1 µF X7R ceramic with low leakage; do not route high-frequency digital signals adjacent to this pin or to the LCD segment pins to avoid display artifacts.
ICSP programming requires RB6/ICCK (pin 26) and RB7/ICCDAT (pin 27) to remain accessible. Provision a 2x3 or 1x6 0.1 inch header footprint on the production PCB even if not populated, to support in-field firmware updates and factory programming. Route both signals with short traces and avoid capacitive loading above 50 pF, or add 4.7 kΩ pull-ups to ensure reliable ICSP communication at low VDD.
The 32 MHz internal oscillator is sensitive to VDD noise; if the ADC reads above 1 LSB of jitter, switch to the LFINTOSC 32 kHz for ADC conversions or use the dedicated FVR (Fixed Voltage Reference) as ADC VREF+. Route the FVR bypass capacitor (0.1 µF) directly to its assigned pin, and keep digital switching traces (PWM, MSSP clock) at least 5 mm away from the ADC input traces to preserve the 10-bit SNR.
