PIC16F19195-E/MR Обзор
The PIC16F19195 belongs to the broader PIC16F1919x family of 8-bit microcontrollers. As an 8-bit MCU, it executes one byte per instruction with a Harvard RISC architecture, optimized for low-power deterministic control. Within the embedded systems hierarchy, this part sits at the 8-bit microcontroller tier — below 16-bit (PIC24) and 32-bit (PIC32) devices — but above simple state machines. It is designed for battery-powered and human-interface applications.
Key features include Microchip's eXtreme Low-Power (XLP) technology, an integrated LCD driver with charge pump, Core Independent Peripherals (CIPs), and intelligent analog (5-bit and 12-bit ADC). The high-current I/O pins support direct LCD backlight drive, while the integrated RTCC with battery backup is well suited for metering and clock applications. The 14KB FLASH and 1024 bytes of RAM support application code for sensor fusion, display rendering, and serial protocol stacks.
The PIC16F19195's architecture pairs an enhanced mid-range 8-bit CPU with up to 32 MHz internal oscillator and rich peripheral integration. The on-chip charge pump simplifies LCD bias generation without external DC-DC components, and the XLP feature set delivers sleep currents below typical microamp levels. The 64-pin QFN footprint exposes a wide peripheral set — multiple UART, SPI, I2C, ADC channels, PWM, and comparators — enabling single-chip implementation of metering, HMI, and IoT sensor nodes.
Typical applications include battery-powered metering with LCD readout, home appliance HMI panels, wearable health monitors, industrial sensor transmitters, and IoT edge nodes. Its CIPs offload tasks from the CPU, freeing cycles for application logic and communication stacks.
When designing, allocate sufficient PCB copper under the QFN exposed pad to dissipate up to ~1 W of power. Always fit the recommended decoupling (100 nF + bulk) within 5 mm of the supply pins, and follow the VQFN land pattern in the manufacturer datasheet for reliable assembly.

Типичное применение
PIC16F19195-E/MR подходит для 6 применениеs: Battery-Powered Metering with LCD Display, Home Appliance HMI Panel, Wearable Health Monitor, Industrial Sensor Transmitter, IoT Edge Sensor Node, Automotive Dashboard Sub-Display.
Battery-Powered Metering with LCD Display
The PIC16F19195-E/MR's eXtreme Low-Power (XLP) technology and integrated LCD driver with charge pump make it ideal for battery-powered metering applications such as gas, water, or electricity meters. XLP delivers sleep currents below typical 1 uA levels, extending battery life across 10+ year deployments. The on-chip charge pump generates the LCD bias voltages without external DC-DC components, reducing BOM cost. The 14 KB FLASH holds metering firmware including tamper detection, calibration tables, and protocol stacks (Wireless M-Bus, NB-IoT, or LoRaWAN). According to Microchip's product page, the integrated RTCC with battery backup maintains timekeeping during main-battery replacement, meeting utility metering regulatory requirements.

Home Appliance HMI Panel
Home appliance front-panel HMIs — washing machines, ovens, and dishwashers — benefit from the PIC16F19195-E/MR's integrated LCD segment driver and high-current I/O pins for direct backlight drive. The 8-bit core at 32 MHz easily handles button-debounce, encoder input, and serial communication with the main appliance controller. Core Independent Peripherals (CIPs) offload PWM for backlight dimming and timer tasks from the CPU. According to the Microchip product page, this part's combination of integrated LCD, ADC, and CIPs enables single-chip implementation of a complete user interface, reducing BOM count versus discrete LCD-driver + MCU designs.

Wearable Health Monitor
Wearable health monitors — heart-rate straps, pulse oximeters, and fitness bands — leverage the PIC16F19195-E/MR's XLP sleep modes to extend battery life to weeks on a single coin cell. The 12-bit ADC captures high-resolution biosensor signals (PPG, ECG, body temperature), while the 5-bit ADC supports quick threshold checks like skin-contact detection. The extended industrial temperature range (-40C to +125C) supports body-temperature environments and outdoor use. According to Microchip documentation, the integrated RTCC enables precise timestamping of health events for sync with smartphone companion apps via Bluetooth Low Energy modules.
Рекомендуется
Industrial Sensor Transmitter
Industrial 4-20 mA loop-powered or wireless sensor transmitters use the PIC16F19195-E/MR for signal conditioning, linearization, and protocol output. The 12-bit ADC digitizes sensor outputs with adequate resolution for process-control loops, while CIPs handle PWM output and timer-based sequencing without CPU load. The extended temperature grade (-40C to +125C) supports outdoor and process-industry environments. According to the Microchip product page, the XLP architecture enables sub-microamp quiescent current for loop-powered 4-20 mA transmitters where the entire circuit must operate under 3.5 mA.
Рекомендуется
IoT Edge Sensor Node
IoT edge sensor nodes combine the PIC16F19195-E/MR's low-power operation with sub-GHz or BLE modules for long-battery-life wireless sensing. The 8-bit core handles sensor sampling, local decision logic, and protocol framing while sleeping between transmissions. The integrated LCD driver supports local display of measurements for diagnostic and commissioning purposes. According to Microchip's product documentation, the eXtreme Low-Power features (deep sleep, low-power RTCC, and peripheral module disable) enable years of operation on two AA batteries when paired with a duty-cycled radio.

Automotive Dashboard Sub-Display
Automotive sub-displays — climate-control panels, audio head-unit secondary screens, and instrument-cluster LCD readouts — match the PIC16F19195-E/MR's extended temperature range and integrated LCD segment driver. The high-current I/O directly drives backlight LEDs, eliminating external drivers and reducing BOM cost. According to Microchip product specifications, the Core Independent Peripherals offload PWM and timer tasks from the CPU, leaving more cycles for CAN/LIN communication and HMI rendering.

Ключевые отличия
- Integrated LCD driver with charge pump eliminates external bias components (против PIC16F18877-I/PT)
- Extended industrial temperature grade for harsh environments (против PIC16F19195-I/MR)
- Compact 9x9 mm QFN footprint with full peripheral access (против PIC16F19195-E/PT)
Заметки по проектированию
The 64-QFN (9x9 mm) exposed pad (EP) must be soldered to a continuous ground plane to dissipate up to ~1 W of internal power and provide electrical ground reference. Estimated: with theta_JA around 30 C/W on a 4-layer JEDEC test board, the EP reduces junction-to-ambient thermal resistance significantly. Use microvia-in-pad (or filled and plated vias) directly under the EP to maximize thermal conductivity. Decoupling capacitors (100 nF + 1 uF bulk) should be placed within 5 mm of each VDD pin.
Leverage the PIC16F19195's XLP features for battery-powered designs: configure unused peripherals to 'module disabled' state, use deep sleep between events, and use the RTCC with internal low-power oscillator for periodic wake-up. The integrated LCD charge pump eliminates the need for an external boost converter for display bias, saving quiescent current. Typical sleep current is documented at sub-1 uA in Microchip's XLP family data.
Verify the supply voltage range before connecting to 5 V systems — the PIC16F19195 family is designed for 1.8 V to 5.5 V operation depending on variant. Using the wrong voltage range can damage the part. When migrating firmware from PIC16F19195 to PIC16F19196 or PIC16F19197, recompile and verify code size; while pin-compatible, the linker scripts may require memory-map updates. Always check errata documents from Microchip before finalizing the design.
