PIC16F19195-E/PT Overview
What is an XLP microcontroller? An XLP (eXtreme Low-Power) microcontroller is a class of MCU specifically architected for battery-powered and energy-harvesting applications. The hypernym hierarchy is: microcontroller -> MCU -> embedded controller -> semiconductor. XLP devices combine multiple low-power modes (sleep, deep sleep, doze, idle) with peripheral clock gating and ultra-low quiescent current, often below 1 uA in deep sleep. The PIC16F19195 adds a segmented LCD driver, making it a single-chip solution for battery-powered human-machine interfaces in metering, medical, and consumer devices.
Key differentiating features include the integrated LCD driver with charge pump, eliminating external bias-voltage circuitry; 12-bit ADC2 with computation, 5-bit DAC, and low-power comparators providing intelligent analog signal conditioning; and Core Independent Peripherals (CIPs) such as CWG, CCP, PWM, ZCD, and SMT that operate without CPU intervention. The Peripheral Pin Select (PPS) feature allows flexible remapping of digital peripherals to I/O pins, simplifying PCB layout.
Architecturally, the PIC16F19195 uses an enhanced mid-range 8-bit CPU core with a hardware stack, hardware multiplier, and instruction prefetch. The device supports ICSP (In-Circuit Serial Programming) and debug, enabling field upgradability. The PMD (Peripheral Module Disable) registers and HLT (Hardware Limit Timer) further extend battery life by allowing firmware to power down peripherals when not in use.
Typical applications include battery-powered blood glucose meters, electronic shelf labels, smart thermostats, portable medical monitors, and any product combining a low-power MCU with a segmented LCD user interface. The high-current I/O (up to 100 mA per pin) can also directly drive small LED backlights without external transistors.
Design consideration: when migrating firmware between PIC16F19195, PIC16F19196, and PIC16F19197 variants, verify that the target pin count and memory size are compatible. The -E suffix denotes the extended -40C to +125C industrial/automotive temperature grade; -I variants operate from -40C to +85C.

PIC16F19195-E/PT is suitable for 7 applications: Battery-Powered Blood Glucose Meter, Electronic Shelf Label (ESL) Wireless Display, Smart Thermostat with LCD User Interface, Portable Patient Monitor, Industrial Process Meter with LCD Display, Solar-Powered IoT Sensor Node, Wearable Fitness Tracker Display.
Battery-Powered Blood Glucose Meter
The PIC16F19195-E/PT is ideal for handheld medical devices such as blood glucose meters that combine a segmented LCD with coin-cell battery operation. Its XLP deep-sleep current below 1 uA and integrated LCD charge pump eliminate boost circuitry, while the 12-bit ADC2 with computation performs accurate glucose-sensor signal processing without CPU wake-up. The 100 mA high-current I/O can directly drive an LCD backlight without a transistor, simplifying the BOM. The 14 KB Flash accommodates strip-detection state machines, calibration tables, and USB-CDC bootloader. Compared to discrete PIC + LCD-driver solutions, the single-chip design reduces PCB area by approximately 30%.
Recommended
Electronic Shelf Label (ESL) Wireless Display
The PIC16F19195-E/PT fits wireless electronic shelf labels that must run for 5+ years on a coin cell. XLP sleep current below 1 uA combined with the integrated LCD driver and charge pump enables display refresh without waking the CPU. The 32 MHz CPU handles LoRa/Sigfox/Sub-GHz radio packet processing when awake, while the RTCC with battery backup maintains timekeeping when the main battery is replaced. The 64-pin TQFP provides ample I/O for SPI radio, I2C sensor, and segmented LCD interface. Compared to nRF51 + LCD-driver solutions, this MCU eliminates an IC and reduces BOM cost by approximately $0.40 per label at volume.
Recommended
Smart Thermostat with LCD User Interface
The PIC16F19195-E/PT drives the segmented LCD user interface of a wall-mounted smart thermostat while the main Wi-Fi/BLE communication is handled by a companion module. The 12-bit ADC2 reads thermistor temperature sensors with 0.1C resolution, and the 5-bit DAC sets reference voltages for the comparator-based HVAC relay control. The CWG and PWM peripherals generate triac firing pulses for AC load switching without CPU intervention. The integrated RTCC maintains time-of-day and 7-day schedule during power outages. Compared to STM32 + discrete LCD-driver designs, this PIC delivers equivalent functionality with lower sleep current and simpler firmware development using MPLAB X IDE.
Recommended
Portable Patient Monitor
The PIC16F19195-E/PT suits portable patient monitors (pulse oximeters, infusion pump status displays) that require medical-grade reliability and an integrated LCD readout. The 12-bit ADC2 with hardware averaging and the low-power comparators perform SpO2 signal conditioning at very low active current. The 256 B EEPROM stores patient calibration data across battery swaps, and the RTCC timestamps readings with year/month/day accuracy. The automotive -40C to +125C temperature grade exceeds typical medical requirements. Compared to discrete MCU + external LCD-driver designs, the integrated charge pump saves PCB area and reduces quiescent current for longer battery life.
Recommended
Industrial Process Meter with LCD Display
The PIC16F19195-E/PT drives 4-20 mA loop-powered process meters used in factories and tank-level gauges. Its wide 2.3-5.5 V supply range supports loop-powered designs running directly from the 4-20 mA signal after shunt regulation. The 12-bit ADC2 measures the loop current with 0.05% accuracy, and the segmented LCD displays the process variable in real time. The ZCD (Zero-Cross Detect) and PWM peripherals can drive an opto-isolated HART modem without CPU load. Compared to ASIC-based loop meters, this MCU allows custom protocol implementation and field firmware upgrades via ICSP.
Recommended
Solar-Powered IoT Sensor Node
The PIC16F19195-E/PT powers solar-charged IoT nodes in agricultural and environmental monitoring where energy budget is critical. XLP sleep current below 1 uA extends battery life during cloudy periods, while the integrated charge pump supports LCD readout at low battery voltages. The RTCC schedules periodic sensor readings and Sub-GHz radio transmissions during the day. The 14 KB Flash accommodates sensor-fusion algorithms and LoRaWAN MAC stack. Compared to ARM Cortex-M0+ MCUs of similar price, this PIC delivers lower sleep current and integrated LCD drive, eliminating one external IC.
Recommended
Wearable Fitness Tracker Display
The PIC16F19195-E/PT drives the segmented LCD of a wearable fitness band, offloading real-time clock and sensor polling from the main BLE SoC. The 100 mA high-current I/O can drive an LED heart-rate sensor directly, and the integrated RTCC timestamps activity logs with sub-second precision. XLP sleep current below 1 uA preserves battery during standby. The PPS feature allows flexible remapping of I2C and SPI to free pins for the segmented LCD. Compared to external LCD-driver + low-power MCU designs, this single-chip solution reduces PCB area and BOM cost for compact wearables.

Design Notes
Estimated: the PIC16F19195-E/PT XLP deep-sleep current is below 1 uA with RTCC enabled per the Microchip datasheet. To achieve this in your design, disable unused peripherals via PMD registers before entering sleep, set all unused I/O as outputs driving low, and ensure the MCLR pull-up is disabled. Add a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 13, 36, 61) and a bulk 10 uF tantalum or ceramic capacitor near the MCU. The integrated LCD charge pump draws additional current proportional to the number of enabled segments and refresh rate - estimate 1-5 uA for typical 4-mux, 32-segment displays.
Place the 32.768 kHz crystal (if used for RTCC) within 5 mm of the SOSC1/SOSC2 pins to minimize stray capacitance. Use a guard ring around the crystal traces connected to ground. For ICD debugging, expose the ICSPCLK (RB6) and ICSPDAT (RB7) pins on test pads or a 0.1-inch header. These pins can be released for general I/O via the PPS mechanism after programming. Keep traces for the segmented LCD COM/SEG lines away from noisy digital signals to prevent ghost-segment artifacts on the display.
Critical: do not enable the LCD charge pump and external VLCD bias generation simultaneously - the datasheet requires exclusive configuration via the LCDCON register. Common mistake: setting CONFIG4 LVP (low-voltage programming) bit enables RB4/5 as I/O but disables the ICD function. Always verify the CONFIG words match your programming tool's template. Another frequent issue: the PPS register must be unlocked (PPSLOCK = 0x55 and 0xAA sequence) before changing pin mappings; otherwise writes are silently ignored.
For optimal ADC2 accuracy, route analog input traces on the opposite side of the PCB from digital signals, and place a ground guard ring around analog pins. Use a single ground plane if possible; if split ground planes are necessary, ensure the analog ground return path does not cross digital return currents. The high-current I/O pins (up to 100 mA) should have wider PCB traces (at least 0.5 mm) and via stitching to the ground plane for thermal dissipation. Avoid placing the MCU directly above or below switching converter inductors to prevent coupled noise.
Compliance Information
RoHS compliant per Microchip product page. The -E temperature grade (-40C to +125C) supports industrial and automotive environments but the part is not AEC-Q100 qualified; for AEC-Q100 automotive applications, request Microchip part numbers with the VAO suffix or contact the factory for the Q-grade equivalent.
