PIC16LF19196T-I/MR Visão geral
An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data path, integrated program memory, RAM, and peripherals intended for embedded control tasks. The PIC16 family sits within the broader taxonomy MCU -> microcontroller -> embedded processor -> integrated circuit -> semiconductor. Within Microchip's portfolio the PIC16LF191xx family adds Core Independent Peripherals (CIPs) and an integrated LCD segment driver with charge pump, targeting low-power battery-driven HMIs.
Key features include the integrated 12-bit ADC2 with computation, a 5-bit DAC, two analog comparators with programmable reference, configurable logic cells (CLC), Complementary Waveform Generator (CWG), Capture/Compare/PWM (CCP) and PWM modules, Zero-Cross Detect (ZCD), Real-Time Clock/Calendar (RTCC) and Peripheral Pin Select (PPS). The device also integrates 256 bytes of EEPROM data memory and supports hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT).
The PIC16LF19196 architecture uses a RISC-style 14-bit instruction word with a 32-level hardware stack and an instruction-cycle-time of four clock periods, yielding 8 MIPS per MHz. The integrated charge pump and LCD driver allow glass bias generation from a single low-voltage rail without external boost components, simplifying BOM count for battery powered meter and appliance displays.
Typical applications include battery powered LCD meters, thermostat and HVAC control panels, portable medical monitors, IoT sensor nodes with segment displays, white goods user interfaces, and remote controls with capacitive touch buttons. The 1.8V minimum Vdd enables single-cell Li-coin or 2x AA-alkaline designs where energy budget is critical.
When designing with this part, choose the LF (low-voltage) variant only if the supply rail will not exceed 3.6V. For 5V-tolerant systems use the PIC16F19196 (5V) variant instead. The 64-QFN package has an exposed pad that must be soldered to the ground plane for thermal and electrical performance per the Microchip datasheet.

Aplicações típicas
PIC16LF19196T-I/MR é adequado para 6 aplicaçãos: Battery Powered LCD Meter, Thermostat and HVAC Control Panel, Portable Medical Monitor, IoT Sensor Node with Segment Display, White Goods User Interface, Remote Control with Capacitive Touch.
Battery Powered LCD Meter
The PIC16LF19196T-I/MR's 1.8V-3.6V wide supply and integrated LCD segment driver with on-chip charge pump make it ideal for battery powered electricity, water, or gas meters. The integrated charge pump generates glass bias voltages (typically 3V-5V) from a single 3V coin cell without external boost components, reducing BOM count by 4-6 parts. XLP nanoWatt sleep currents below 100 nA extend coin-cell life to 10+ years in metrology duty cycles.
Recomendado
Thermostat and HVAC Control Panel
The PIC16LF19196T-I/MR's 28KB Flash, integrated 12-bit ADC2, and PWM peripherals suit thermostat and HVAC controller designs that need to read temperature sensors, drive TRIACs, and display status on segmented LCD. The ADC2 with computation automates averaging and threshold detection in hardware, offloading the CPU. CLC and CWG enable dead-band control of complementary power stages for synchronous motor or PFC drive.
Recomendado
Portable Medical Monitor
The PIC16LF19196T-I/MR suits portable medical monitoring devices such as pulse oximeters, glucometers, and blood pressure cuffs that need low-power analog front ends and segmented LCD output. The 12-bit ADC2 with computation provides automated oversampling and threshold detection required for vital-sign sensor front ends, while the XLP sleep modes keep average current below 5 uA for multi-day battery operation on a single CR2032 cell.
Recomendado
IoT Sensor Node with Segment Display
The PIC16LF19196T-I/MR combines eXtreme Low-Power XLP sleep modes (down to 30 nA in Retention mode) with Core Independent Peripherals that wake the CPU only on sensor threshold events. The integrated LCD driver displays readings without an external display controller, while ZCD and RTCC allow line-powered or battery duty-cycled operation. PPS enables flexible pin remapping for compact 4-layer PCB layouts.
Recomendado
White Goods User Interface
The PIC16LF19196T-I/MR powers the LCD user interface of washing machines, dishwashers, and ovens that need 30-50 segment displays plus motor/relay control. The CWG, PWM, and CCP modules drive brushless DC or universal motors directly, while the LCD charge pump drives TN/STN glass. The industrial -40C to +85C temperature grade handles appliance thermal stress near motors and heaters.
Recomendado
Remote Control with Capacitive Touch
The PIC16LF19196T-I/MR with mTouch capacitive touch sensing library and integrated LCD output suits remote controls that need 10-20 touch buttons plus a multi-segment status display. The CTMU peripheral provides hardware capacitive touch measurement with sub-10 pF resolution, and the ADC2 reads battery voltage for low-battery warning. PPS enables PCB routing flexibility for compact remote-control form factors.

Notas de projeto
The 64-QFN package has a thermal resistance (theta_JA) of approximately 32 C/W on a standard 4-layer JEDEC test board. The exposed pad (pin 64) MUST be soldered to the PCB ground plane with thermal vias to keep junction temperature within the -40C to +85C industrial range. Estimated: at full 32 MHz CPU load and all peripherals active, core current is approximately 6 mA at 3.3V, yielding 20 mW dissipation and a 0.6 C junction rise - well within thermal limits. However, charge-pump load from a large LCD glass can add 1-3 mA continuously, increasing dissipation to 30 mW with a 1 C rise above ambient.
Place decoupling capacitors (100 nF ceramic + 10 uF bulk) within 3 mm of each VDD pin pair (pins 9/10, 27/28, 61/62). The VCAP pin (pin 63) requires a 1 uF to 10 uF ceramic bypass with ESR < 100 milliohm. Route analog AVSS/AVDD pairs separately from digital supplies with a star-ground topology to avoid ADC2 noise injection. Per datasheet DS40001974, place the VCAP cap on the same side as the IC with no via between pin and capacitor pad.
The PIC16LF19196T-I/MR supports multiple XLP sleep modes: Sleep mode at < 50 nA typical, Retention mode at < 100 nA with RAM preserved, and Deep Sleep mode with RTCC active at < 500 nA. For battery-powered LCD meters, use Sleep mode between LCD refreshes and wake the RTCC every 250 ms to update the display. Estimated: 1.5 V CR2032 capacity of 220 mAh divided by 5 uA average current yields approximately 5 years of operation - confirm by integrating the actual application duty cycle.
Do not connect MCLR (RA3, pin 23) directly to VDD without a series resistor - lightning/ESD transients can exceed the absolute maximum rating. Use a 10 kohm pull-up and a diode clamp. Do not exceed VDD + 0.3V on any I/O pin including RA3 when configured as MCLR. For in-circuit programming, add a 100 ohm series resistor on ICSPCLK (RB6) to limit programming current into the debugger. Programming voltage must be removed before normal operation begins.
