PIC16F1719T-I/PT Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus that integrates a CPU, Flash program memory, RAM, and a rich set of peripherals on one die. MCUs sit within the broader semiconductor hierarchy of embedded processors -> microcontrollers -> microcontrollers with integrated peripherals -> PIC XLP family -> 8-bit PIC16F1xxx enhanced mid-range core. The "XLP" branding indicates eXtreme Low Power design, making these MCUs well suited to battery-powered or energy-harvesting products. The "T-I/PT" suffix denotes Tape & Reel packaging, Industrial operating temperature range (-40C to +85C), and the 44-pin TQFP package.
Key features of the PIC16F1719 include on-chip operational amplifiers, Core Independent Peripherals (CIP) such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG), Numerically Controlled Oscillator (NCO), and Zero Cross Detect (ZCD), as well as Peripheral Pin Select (PPS) for flexible signal routing. The 10-bit ADC, 5-bit and 8-bit DACs, and PWM modules with CCP support allow direct analog control without external components.
The device implements an enhanced mid-range 8-bit RISC core with a 14-bit instruction word, providing 49 instruction types and a single-cycle ALU operating at up to 32MHz. Internal oscillator options and the nanoWatt XLP sleep modes deliver idle currents typically below 1 uA, making the part suitable for always-on sensing applications.
Typical applications include LED lighting control, sensor signal conditioning, low-power IoT edge nodes, HVAC actuator interfaces, and general purpose industrial control where analog integration reduces BOM cost. The Peripheral Pin Select feature allows the same GPIO pad to map to multiple internal peripherals, simplifying PCB layout.
When designing with the PIC16F1719T-I/PT, place 100nF decoupling capacitors near each VDD pin and consider the exposed pad thermal dissipation path. MPLAB X IDE and the XC8 compiler provide full development support with free software tools and application libraries for the CIP peripherals.

Aplicações típicas
PIC16F1719T-I/PT é adequado para 6 aplicaçãos: LED Lighting Control, Industrial Sensor Signal Conditioning, Low-Power IoT Edge Nodes, HVAC Actuator Interfaces, General Purpose Industrial Control, Battery Management Front-End.
LED Lighting Control
The PIC16F1719T-I/PT is well suited to LED lighting control because its Complementary Output Generator (COG) and PWM modules drive half-bridge LED strings with hardware-defined dead time, eliminating software jitter. The 32MHz core and 28KB Flash comfortably host DMX, DALI, and custom wireless lighting protocols. Its 10-bit ADC senses ambient light for closed-loop dimming, while the on-chip op amps amplify photodiode signals directly. The XLP nanoWatt sleep modes drop current to under 1 uA between brightness commands, supporting battery-backed wireless lighting nodes.
Recomendado
Industrial Sensor Signal Conditioning
The PIC16F1719T-I/PT integrates on-chip operational amplifiers, 10-bit ADC, and 5/8-bit DACs, forming Microchip's Intelligent Analog subsystem that conditions sensor signals without external op amps. The Core Independent Peripherals (CLC, NCO, ZCD) implement zero-crossing detection, frequency synthesis, and logic gating in hardware, offloading the 8-bit core from real-time tasks. PPS allows flexible routing of UART, I2C, and SPI to any GPIO, simplifying PCB layout in mixed-signal industrial modules. With 28KB Flash, sensor calibration curves and linearization tables fit in-program.
Recomendado
Low-Power IoT Edge Nodes
The PIC16F1719T-I/PT's eXtreme Low Power (XLP) technology and nanoWatt sleep modes deliver typical sleep currents under 1 uA, enabling battery-powered IoT edge nodes that last years on a single coin cell. Its 2KB RAM supports small sensor buffering, while 28KB Flash holds BLE/Zigbee stack fragments or LoRaWAN MAC logic. The on-chip 10-bit ADC reads battery voltage, temperature, and environmental sensors before sleep, while PPS and CLC enable wake-up on external events without CPU intervention. The 44-TQFP package suits compact sensor modules.
Recomendado
HVAC Actuator Interfaces
The PIC16F1719T-I/PT drives HVAC damper and valve actuators via PWM and the COG peripheral, which generates hardware-timed complementary outputs for H-bridge drivers with deterministic dead time. Its 32MHz instruction rate sustains real-time PID loops running at 1 kHz or faster, while 2KB RAM retains setpoint history. The on-chip op amps amplify thermistor bridge signals, and the 10-bit ADC reads up to multiple temperature channels. Industrial -40C to +85C rating and 44-TQFP PCB compatibility make it a strong fit for HVAC controllers.
Recomendado
General Purpose Industrial Control
The PIC16F1719T-I/PT serves general industrial control tasks such as relay sequencing, contactor debounce, encoder reading, and discrete I/O expansion. Its EUSART, I2C, and SPI interfaces connect to MODBUS, IO-Link, and proprietary fieldbuses, while PPS reassigns peripherals to different GPIOs to match PCB routing. With 28KB Flash, application firmware plus bootloader fits easily. The CLC can implement safe-state interlocks in hardware without firmware intervention, providing deterministic fault response in industrial environments.
Recomendado
Battery Management Front-End
The PIC16F1719T-I/PT functions as a battery management front-end, using its 10-bit ADC and on-chip op amps to monitor cell voltage, current shunt, and thermistor temperatures. The 5-bit and 8-bit DACs generate voltage references for threshold comparison. The ZCD peripheral detects AC charger zero-cross events for synchronous timing. With 2KB RAM, charge-state history buffers fit comfortably, and 28KB Flash holds state-machine lookup tables. The XLP sleep mode drops consumption between battery sample intervals.

Notas de projeto
Estimated: The PIC16F1719T-I/PT typically draws 8 mA at 32MHz with all peripherals active and drops to under 1 uA in XLP sleep mode. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 10 and 41) and a bulk 10 uF tantalum or ceramic on the main supply rail. For battery applications, gate the MCU's VDD via a load switch and use the Peripheral Pin Select to wake on RTC or external interrupts.
The 44-TQFP package has a 0.8 mm pin pitch and 10x10 mm body; reserve at least 1.5 mm of clearance beyond the package outline for trace routing and rework. Place the decoupling capacitors on the same layer as the MCU to minimize inductance. Use a star-ground topology with the MCU's VSS pins (11 and 42) tied to a single ground plane via to reduce digital switching noise coupling into analog inputs.
When using the on-chip 10-bit ADC, dedicate an AVSS/AVDD pair (if available, otherwise route VDD/VSS directly) and add a small RC filter at each analog input. Keep analog traces short and avoid routing them parallel to PWM or COG switching outputs. The Peripheral Pin Select feature allows digital functions to be mapped away from analog-capable pins, reducing cross-talk on the same I/O port.
Do not leave the MCLR pin (RE3, pin 40) floating; tie it to VDD through a 10 kOhm pull-up resistor or a filtered RC network for proper reset behavior. When programming via ICSP, ensure the PGC (RB6) and PGD (RB7) pins are not driven by external circuitry during programming, or use isolation resistors. Configuring the PPS module incorrectly will silently route signals to wrong peripherals; always verify PPS mappings against the device header file in MPLAB X.
