PIC16F1719-I/PT - 8-Bit 32MHz 28KB Flash MCU | Microchip 44-TQFP
MPN: PIC16F1719-I/PT ✓ فعالPIC16F1719-I/PT جائزہ
A microcontroller (MCU) in this class is a single-chip computer that combines a CPU core, non-volatile flash memory, RAM, and a configurable set of analog and digital peripherals. PIC16F MCUs use a RISC-based 8-bit Harvard architecture with a 14-bit instruction word, sitting between 8-bit PIC10/PIC12 baseline parts and higher-pin-count PIC18 devices. Within the broader taxonomy, PIC16F1719 belongs to Microcontrollers > 8-bit MCUs > PIC16F Family > PIC16F171x Sub-family > Integrated Analog & XLP variants.
Key features include 35 instructions, two 8-bit timers, four 16-bit timers, an 8-channel 10-bit ADC, a 5-bit/8-bit/10-bit DAC, two comparators, two op amps, 36 I/O pins, and an internal oscillator. The wide 2.3V–5.5V operating range supports both 3.3V and 5V rails. Industrial temperature grade (-40 °C to +85 °C, denoted by the -I suffix) and the 44-TQFP (PT suffix) surface-mount package make it a drop-in option for cost-sensitive general-purpose designs.
Typical applications include IoT sensor nodes, consumer appliances, low-power battery-powered instruments, LED lighting controllers, and small motor-control / signal-conditioning front ends. Core Independent Peripherals offload timing-critical logic from the CPU, lowering firmware complexity and active-mode current. The on-chip op amps and DAC simplify analog front-end design, often removing the need for external analog ICs.
When designing with this part, ensure the ICSP™/ICD programming header is accessible for in-circuit debug and that VDD decoupling (100 nF + 1 µF) sits within 5 mm of the supply pins.

IoT Sensor Node with On-Chip Analog Front End
The PIC16F1719-I/PT fits battery-powered IoT sensor nodes because its 28 KB flash and Core Independent Peripherals (CLC, COG, NCO) handle wake-up, event sequencing, and protocol framing without CPU intervention. The two on-chip op amps condition thermistor, strain-gauge, or photodiode signals directly, while the 10-bit ADC and 5-/8-/10-bit DAC close the analog loop. XLP sleep currents below 1 µA extend coin-cell life to multi-year horizons. Placed on a 2-layer 1.6 mm FR-4 board with a 32.768 kHz crystal for RTC, the part replaces a discrete op-amp + 8-bit MCU stack and shrinks BOM cost.

Consumer Appliance User Interface Controller
Household appliances (coffee machines, induction cooktops, washing-machine HMIs) benefit from the PIC16F1719-I/PT's 36 GPIO pins driving segmented LCDs, capacitive touch via Peripheral Pin Select, and zero-cross detect for TRIAC dimming. The 44-TQFP package fits behind the display PCB and the industrial -40 °C to +85 °C temperature range survives kitchen environments. Compared to discrete logic, the 32 MHz CPU + 28 KB flash holds full state-machine firmware plus a USB-CDC bootloader, while the 2 on-chip comparators handle over-temperature shutdown without external hardware.

LED Lighting Controller with Constant-Current Driver
Smart LED drivers use the PIC16F1719-I/PT's CLC (Configurable Logic Cell) to implement constant-current regulation in hardware, freeing the CPU to run DMX-512 or DALI protocol stacks from the 28 KB flash. The COG (Complementary Output Generator) drives high-side/low-side MOSFET pairs with programmable dead-band, while the 10-bit DAC sets the current reference. With 32 MHz CPU bandwidth, the part supports 8 channels of 16-bit PWM at 1 kHz update rate. Industrial temperature rating and 2.3–5.5 V VDD let the same firmware operate across 3.3 V and 5 V LED strings.

Battery-Powered Handheld Instrument
Handheld multimeters, portable gas detectors, and medical monitors leverage the PIC16F1719-I/PT's XLP sleep current (<1 µA typical) and 2 KB RAM for data buffering between measurement cycles. The two on-chip op amps form a transimpedance amplifier for optical sensors and a buffer for the 10-bit ADC. PPS lets the same PCB host either SPI flash or an LCD by remapping pins. Industrial temperature grade supports field use, and the 44-TQFP (PT) footprint keeps the design hand-solderable for low-volume production runs.

Low-Speed BLDC / DC Motor Control
Small BLDC fans, pumps, and DC motor controllers use the PIC16F1719-I/PT's COG peripheral for hardware dead-band generation, the 10-bit ADC for back-EMF sensing, and the 16-bit timers for precise PWM at up to 32 MHz CPU clock. The on-chip comparators provide hardware over-current protection with cycle-by-cycle current limiting. With 28 KB flash, the part holds sensored and sensorless FOC firmware variants, switching between them at runtime via the bootloader. The 44-TQFP package drops onto standard motor-control PCBs without layout changes.

Industrial Signal Conditioning Module
PLC analog input modules and 4–20 mA loop isolators use the PIC16F1719-I/PT's two on-chip op amps to build instrumentation amplifiers and active filters before the 10-bit ADC. The 5-bit/8-bit/10-bit DAC generates 4–20 mA loop current when paired with a current transmitter. CLCs debounce noisy digital inputs in hardware, while PPS routes UART/SPI to RJ-45 or terminal-block headers without a board spin. The 2.3–5.5 V VDD tolerates 24 V industrial rails after regulation, and the industrial -40 °C to +85 °C temperature rating handles cabinet environments.

ڈیزائن نوٹس
Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin (11 and 32 on TQFP-44), plus a bulk 1 µF X7R on the VDD net. For battery applications, configure XLP Sleep mode by clearing the IDLEN bit and gating peripherals via PMD registers; sleep currents under 1 µA are achievable when all PMDs are disabled.
Keep ICSP™ pins RB6 (ICSPCLK) and RB7 (ICSPDAT) accessible on the production PCB - either with test pads or a 2×3 0.1 inch header. The TQFP-44 has 0.8 mm lead pitch; use ENIG finish and 0.15 mm solder mask expansion for reliable reflow. Ground the exposed pad (if present) to VSS via at least 4 thermal vias for mechanical stability.
Do not exceed 5.5 V on any I/O pin - the absolute maximum is 6.0 V but operation above 5.5 V stresses the ESD diodes. Configure unused I/O pins as outputs driving low to minimize sleep current. When using the on-chip op amps, ensure the non-inverting input stays within VSS–VDD; rail-to-rail behavior is not guaranteed below 2.5 V VDD.
Route analog signals (op-amp inputs, ADC channels) on a separate layer from digital switching traces. Place the AVREF+ bypass cap within 3 mm of pin 4 (RA3 reference) and isolate the analog ground pour under the MCU's analog pins (RA0–RA7). For ZCD or comparator inputs, add 100 pF–1 nF RC filters to suppress high-frequency noise coupling from PWM traces.
When driving external SPI flash or I²C peripherals, add 10 kΩ pull-ups on SDA/SCL even though the PIC16F1719 has weak internal pull-ups. PPS remapping lets you place I²C on any available pin; reserve a PPS pair (e.g., RC3/RC4) for I²C to avoid remapping in production. Use IOC (Interrupt-On-Change) for low-power wake instead of polling GPIO states.
