PIC16F1719-E/PT Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and a rich set of peripherals (ADC, timers, communication interfaces) onto one silicon die. Within the semiconductor taxonomy, an MCU sits under Embedded IC -> Integrated Circuit -> Semiconductor. The PIC16F family occupies Microchip's mid-range 8-bit portfolio, offering a balance of low power, deterministic execution, and integrated analog for general-purpose embedded designs.
Key features include extreme low-power (XLP) technology with multiple Idle/Doze/sleep modes, 35 instructions, vectored interrupts, 256 bytes of EEPROM, four 8-bit timers and one 16-bit timer, two CCP modules supporting PWM, an Enhanced USART (EUSART), and MSSP for I2C/SPI. The PPS module remaps digital peripheral I/O to any device pin, simplifying PCB layout and BOM reuse across PIC16F1717/8/9 derivatives.
The PIC16F1719 uses Microchip's enhanced mid-range 8-bit RISC core, manufactured on a low-power CMOS process. The Harvard architecture keeps program and data buses separate for deterministic single-cycle instruction execution except for program branches. Integrated analog front-ends (op-amp, 10-bit ADC, DAC, comparator) reduce external component count, while the COG/CLC/NCO blocks allow waveform generation and logic operations without CPU intervention.
Typical applications include LED lighting control, consumer white goods, sensor conditioning nodes, low-cost motor control (PWM/COG), battery-powered IoT edge nodes, and general-purpose mixed-signal embedded designs that benefit from on-chip analog and Core Independent Peripherals.
When designing with this MCU, allocate sufficient decoupling (100nF plus 10uF bulk) close to VDD pins and follow Microchip's TQFP-44 land-pattern guidelines. For low-power designs, leverage the XLP sleep modes and the Peripheral Pin Select routing map from the datasheet.

Aplicações típicas
PIC16F1719-E/PT é adequado para 6 aplicaçãos: LED Lighting Control, Mixed-Signal Sensor Conditioning Nodes, Battery-Powered IoT Edge Nodes, Low-Cost Motor Control (PWM + COG), Consumer White Goods Control Boards, General-Purpose Mixed-Signal Embedded Designs.
LED Lighting Control
The PIC16F1719-E/PT is well suited to LED lighting controllers that mix dimming PWM, analog current sensing, and serial control because it pairs four 8-bit timers and a 16-bit timer with two CCP modules that generate high-resolution PWM at the 32MHz core speed. The on-chip high-speed comparator and op-amp let you close a constant-current feedback loop around an external MOSFET without adding a dedicated LED driver IC, while the Peripheral Pin Select remaps PWM outputs to any GPIO for flexible PCB routing. This combination reduces BOM by one or two analog parts compared with discrete MCU-plus-driver designs and keeps the firmware response deterministic for flicker-sensitive dimming.
Recomendado
Mixed-Signal Sensor Conditioning Nodes
In sensor-conditioning hubs the PIC16F1719-E/PT brings together a 10-bit ADC, a 5/8-bit DAC, two on-chip op-amps, and a high-speed comparator on a single die, eliminating the discrete analog chain that low-end MCUs require. The Core Independent Peripherals (CLC, NCO, ZCD) generate timing and zero-cross triggers without CPU intervention, leaving the enhanced mid-range 8-bit core free for sensor-fusion logic. Industrial -40C to +125C operation allows deployment in factory floors and outdoor enclosures without additional thermal qualification, and the wide 1.8V to 5.5V supply range simplifies battery or bus-powered sensor designs.
Recomendado
Battery-Powered IoT Edge Nodes
The PIC16F1719-E/PT's eXtreme Low Power (XLP) sleep modes with sub-microamp currents, combined with the wide 1.8V to 5.5V VDD range, let the device run for years on a CR2032 coin cell in remote sensor applications. The on-chip 32MHz internal oscillator removes an external crystal for typical sub-MHz peripheral tasks, cutting quiescent draw and BOM cost. Core Independent Peripherals handle pulse counting, NCO-based waveform synthesis, and zero-cross detection while the CPU remains in deep sleep, so the average system current stays at the leakage floor rather than the active-clock level.
Recomendado
Low-Cost Motor Control (PWM + COG)
The Complementary Output Generator (COG) peripheral on the PIC16F1719-E/PT produces hardware-timed complementary PWM with programmable dead-band, which is exactly the signal pair a half-bridge MOSFET driver expects for brushed-DC or small BLDC motors. Pairing COG with the 16-bit timer gives 32MHz-edge resolution on the PWM frequency, and the on-chip op-amps measure shunt current for closed-loop torque control without an external amplifier. The integrated high-speed comparator triggers protection trips in hardware within a few hundred nanoseconds, far faster than a firmware interrupt path could respond.
Recomendado
Consumer White Goods Control Boards
White-goods control boards - washing machines, dishwashers, microwave ovens - need a single MCU that drives a user interface, reads sensors, runs a motor or heater, and communicates with the main controller, all at a tight BOM cost. The PIC16F1719-E/PT hits all of these notes: 28KB of Flash absorbs state-machine firmware plus a UI menu, the integrated EUSART and MSSP expose RS-485 and I2C for inter-board comms, and the 44-TQFP gives enough pins for a keypad matrix plus relay drives. Industrial temperature tolerance and on-chip op-amps simplify analog sensor inputs.
Recomendado
General-Purpose Mixed-Signal Embedded Designs
The PIC16F1719-E/PT is the right PIC16 for general-purpose mixed-signal boards because it is the top-memory variant of the PIC16F1717/8/9 family and exposes every peripheral the family includes. Designers prototype on the 44-TQFP and then drop down to the smaller-flash PIC16F1718 or PIC16F1717 in the same package once the code stabilizes, cutting BOM cost on production runs. Combined with MPLAB X IDE support, the PICkit 4 debugger, and a large base of legacy PIC firmware, it is a safe choice for engineering teams that want to standardize on one MCU family across multiple product lines.

Notas de projeto
Decouple every VDD pin with a 100nF ceramic capacitor placed within 2-3mm of the pin, and add a single 10uF bulk capacitor near the VCAP pin or the highest-impedance VDD rail. The PIC16F1719-E/PT operates across 1.8V to 5.5V; when VDD is below 2.5V, the on-chip op-amp bandwidth drops and the ADC reference must be set to VDD rather than an internal 4.096V bandgap. Place a 1M-ohm pull-up on MCLR to keep the part out of reset during power-up ramps slower than 50ms.
At 32MHz full-speed operation from 5V VDD, the PIC16F1719-E/PT draws about 8-12mA of core current. The 44-TQFP package has a theta_JA of approximately 45-55 C/W depending on PCB copper area; at 5V VDD and full I/O switching, junction temperature stays well below the 150C limit in normal ambient. Estimated: at 25C ambient, expect a 4-6C junction rise for typical GPIO loading. For sealed IP65 enclosures without airflow, derate peripheral count to keep total power dissipation under 100mW.
Always configure the unused I/O pins as outputs driving low, not as inputs, to avoid floating-pin supply current that can add 50-100uA per pin in deep sleep. The MCLR pin must be tied to VDD through a 10k-ohm resistor; leaving it floating causes intermittent resets in noisy environments. When using the on-chip op-amps, the CHAN bits in the OPAxCON register must be set before enabling the module, otherwise the input stage floats and draws tens of microamps extra.
Route the analog signals (RA0-RA5, RC0-RC3, RE0-RE3) on a separate layer or with a guard trace to digital traces carrying PWM outputs and serial clocks; the PIC16F1719-E/PT shares its I/O ring between analog and digital functions, and the on-chip ADC exhibits 1-2 LSB degradation from digital switching noise above 50MHz edge rates. Keep the VCAP trace short (under 5mm) and flood copper around the analog VDD/VSS pair to provide a low-impedance reference for the ADC.
