PIC16F19186-E/PT 概要
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus and Harvard or modified-Harvard architecture; the PIC16F19186 is a member of Microchip's PIC16 enhanced mid-range family (PIC16 -> 8-bit MCU -> microcontroller -> embedded computing device). It executes most instructions in a single clock cycle and provides deterministic interrupt latency, which is why PIC MCUs are commonly chosen for real-time control, low-power sensing, and human-machine interface (HMI) panels.
Key features of this device include 28KB (16K x 14) Flash program memory, 2KB SRAM data memory, 256B EEPROM, integrated 12-bit ADC2 with computation, a 5-bit DAC, low-power comparators, CCP, PWM, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), RTCC, Hardware Limit Timer, WWDT, and Power Management Module (PMD). The -E industrial temperature grade spans -40C to +125C.
Architecture-wise, the device pairs the enhanced mid-range PIC core with on-chip LCD drive hardware, an internal charge pump to bias the LCD glass from a low-voltage supply, and a high-current I/O capability, reducing the external BOM for segment LCD designs. The XLP technology suite (idle/doze/sleep modes + nanoWatt XLP peripherals) enables microamp-level sleep currents.
Typical applications include battery-powered LCD consumer appliances, IoT sensor nodes with segment displays, e-meter / home-automation keypads, portable medical monitoring with LCD readouts, and ruggedized industrial HMI panels. The integrated LCD controller and charge pump allow direct drive of glass displays without a separate bias generator.
When designing with the PIC16F19186-E/PT, ensure the VDDCORE is properly decoupled (typically 0.1uF + bulk) and follow Microchip's LCD bias and charge-pump capacitor recommendations (typically 0.1uF to 1uF) for stable contrast. Use PPS to remap peripherals and avoid pin-conflict routing on the 48-pin TQFP. For lowest sleep current, gate unused peripherals via the PMD register.

主な用途
PIC16F19186-E/PT の用途: 7 件s: Battery-Powered LCD Consumer Appliances, IoT Sensor Nodes with Segment LCD, Smart Home HMI Keypads and Thermostats, Industrial HMI and Panel Meters, Portable Medical Monitoring Devices, Automotive Cabin HMI and Dashboard Sub-Displays, E-Meter and Utility Meter Displays.
Battery-Powered LCD Consumer Appliances
The PIC16F19186-E/PT is purpose-built for battery-powered LCD consumer appliances such as portable kitchen scales, blood-pressure monitors, and remote-control panels with segment displays. Its integrated charge pump drives the LCD glass directly from a 3V coin cell without an external bias generator, while XLP technology drops sleep current into the nanoamp range - critical for applications where two AA cells must last 2+ years. The 12-bit ADC2 with computation handles sensor readings on-chip, reducing MCU wake time. Compared with discrete MCU + LCD driver solutions, the integrated architecture saves PCB area and BOM cost while the 32 MHz CPU keeps button-debounce and UI logic responsive.
おすすめ
IoT Sensor Nodes with Segment LCD
The PIC16F19186-E/PT fits IoT sensor nodes that need a local segment-LCD readout (temperature, humidity, air-quality displays) because the on-chip LCD controller eliminates an external driver and the Peripheral Pin Select (PPS) allows flexible I/O mapping for sensors and radios. The 32 MHz CPU runs Microchip's Modbus or proprietary RF stacks, while the SMT (Signal Measurement Timer) captures sensor pulse streams without CPU intervention. Battery life is dominated by sleep current, which XLP technology targets at sub-1uA - enabling years of operation from a primary cell. The 256B EEPROM stores calibration constants that survive battery swap events.
おすすめ
Smart Home HMI Keypads and Thermostats
Wall-mounted smart-home keypads and thermostats benefit from the PIC16F19186-E/PT because the integrated LCD driver directly addresses segment displays (time, temperature, setpoint) without extra ICs, while the capacitive touch-ready I/O and PWM channels handle backlight dimming and haptic feedback. The -E temperature grade (-40C to +125C) handles indoor environments near heating ducts or exterior walls. RTCC provides accurate timekeeping across power cycles with on-chip 32 kHz crystal support, and ZCD (Zero-Cross Detect) enables silent triac control of AC loads for line-voltage thermostats. Engineers gain BOM reduction versus MCU+LCD-driver+ RTC three-chip solutions.
おすすめ
Industrial HMI and Panel Meters
The PIC16F19186-E/PT powers industrial HMI panels and panel meters where a segment LCD shows process variables (pressure, flow, voltage) in 4-20 mA loop-powered environments. The 12-bit ADC2 with computation oversamples and averages noisy industrial signals on-chip, freeing the CPU to manage Modbus RTU over UART. The Hardware Limit Timer (HLT) and Windowed Watchdog (WWDT) meet functional-safety expectations for fault detection, while the -E temperature grade survives +85C cabinet interiors. The integrated CWG generates complementary PWM for synchronous buck pre-regulators feeding the analog supply rails.
おすすめ
Portable Medical Monitoring Devices
Portable medical devices (pulse oximeters, glucose meters, digital thermometers) use the PIC16F19186-E/PT because XLP technology supports the IEC 60601-01 low-current sleep profile that AAA or coin cells demand, while the integrated LCD driver shows readings on the device's segment display without a second chip. The 12-bit ADC2 captures pulse or temperature waveforms with hardware averaging, and the CCP/SMT timers measure pulse intervals precisely for SpO2 calculations. Microchip's medical-grade quality and documentation support IEC 60601-1 design review. PPS allows routing sensitive analog inputs away from digital switching noise.
おすすめ
Automotive Cabin HMI and Dashboard Sub-Displays
Within automotive cabin HMI and sub-displays (climate-control readouts, mirror displays, seat-controller panels), the PIC16F19186-E/PT serves as a segment-LCD sub-display driver because its -40C to +125C industrial grade handles cabin thermal swings, while the integrated charge pump and LCD controller replace a separate LCD-driver ASIC. The PWM + CWG pair handles LED backlight dimming, and LIN bus-ready UART connects to the body-control module. Engineers pair the PIC with a CAN/LIN transceiver and use the CCP modules to interpret HVAC rotary encoders. Note: a fully AEC-Q100 qualified variant would be required for under-hood applications.
おすすめ
E-Meter and Utility Meter Displays
Single-phase e-meters and utility sub-meters with segment LCD readouts use the PIC16F19186-E/PT to drive consumption displays while an external metrology IC handles energy measurement. The RTCC tracks time-of-use tariffs, and the 256B EEPROM stores calibration and billing snapshots that survive brownouts. The integrated 12-bit ADC2 monitors the meter's own supply and battery backup, while ZCD detects mains zero-crossings for accurate reactive-power timestamping. The CWG can drive an audible alarm transducer for tamper alerts. XLP sleep modes keep the meter's parasitic draw within utility regulatory limits.

設計ノート
Decouple VDD and VDDCORE with a 0.1uF ceramic capacitor placed within 3 mm of each pin pair, plus a bulk 1-10uF tantalum or ceramic capacitor. The PIC16F19186-E/PT VDDCORE pin must be tied only to its decoupling cap - do not load it externally, as it is the internal regulator output. For battery applications, gate unused peripherals using the PMD register to drop sleep current below 1 uA.
Do not skip the LCD bias capacitor network recommended in the PIC16(L)F19186 datasheet; absent capacitors cause low contrast and ghost segments. When using the integrated charge pump, populate both the charge-pump capacitor (typically 0.1uF) and the VLCD bypass (typically 0.1uF to 1uF). Also remember to enable the LCD charge pump in the LCDCON register before segment activation.
Route the ICSP/ICD pins (RA0/ICSPDAT, RA1/ICSPCLK) so they can be accessed by the programmer header without crossing analog traces. Place the 32 kHz crystal within 5 mm of OSC1/OSC2 with a guard ground ring for RTCC accuracy. Keep LCD segment traces short and matched in length within a group to minimize ghost-segment artifacts.
When using PPS to remap peripherals, always clear and reconfigure PPS registers around writes to avoid transient glitches on remapped functions. The ZCD (Zero-Cross Detect) input should be AC-coupled through a current-limiting resistor when monitoring mains - never connect mains directly to the ZCD pin. For noisy industrial environments, use the 12-bit ADC2 hardware averaging and oversampling features to suppress 50/60 Hz interference.
