PIC16F1719T-I/MV - 8-Bit 32MHz 28KB Flash MCU 40-UQFN | Microchip
MPN: PIC16F1719T-I/MV ✓ Hoạt độngPIC16F1719T-I/MV Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory (RAM), and a rich set of peripherals (ADCs, timers, communication interfaces, I/O). PIC microcontrollers from Microchip use a Harvard RISC architecture optimized for deterministic, low-power embedded control. The PIC16F1719 belongs to the mid-range PIC16 family and targets cost-sensitive applications requiring on-chip analog signal conditioning rather than external op-amps and comparators.
Key differentiating features include integrated operational amplifiers, Core Independent Peripherals (Configurable Logic Cells CLC, Complementary Output Generator COG, Numerically Controlled Oscillator NCO, and Zero-Cross Detect), Peripheral Pin Select (PPS) for flexible signal routing, and eXtreme Low Power (XLP) sleep currents as low as . The on-chip op-amps allow direct interfacing with sensors without external analog front-end components, reducing BOM cost and PCB area.
Technically, the device uses a 14-bit instruction word RISC core with 49 instructions, hardware stack, and 32 MHz internal oscillator. The 10-bit ADC with computation (ADC2) automates averaging, threshold comparison, and oversampling, while the CLCs let designers build custom logic glue without CPU intervention. PPS allows remapping of digital peripherals onto any I/O pin, simplifying PCB layout.
Typical applications include LED lighting and signage drivers (using COG for half-bridge control), IoT sensor nodes (using XLP and ADC2 for battery monitoring), industrial control (using op-amps for 4-20 mA loop interfaces), consumer appliance control, and general-purpose sensor signal conditioning. The PIC16F1719 combines the analog integration of a small mixed-signal MCU with the low-power credentials of an XLP device, making it a strong fit for energy-aware embedded designs.
When designing with this part, plan for in-circuit serial programming (ICSP) via the PGD/PGC pins and reserve adequate UQFN thermal pad soldering per IPC-7351 guidelines. Decouple VDD with at least a 100 nF plus 10 uF bulk capacitor close to the supply pins. Use PPS deliberately - remapping digital functions after layout is final can save respins.

Ứng dụng tiêu biểu
PIC16F1719T-I/MV phù hợp cho 6 Áp dụngs: LED Lighting and Signage Drivers, Industrial Sensor Signal Conditioning, IoT Sensor Nodes and Battery Monitoring, Consumer Appliance Control, Power Conversion and SMPS Secondary-Side Control, Automotive Body and Interior Modules.
LED Lighting and Signage Drivers
The PIC16F1719's on-chip Complementary Output Generator (COG) produces hardware-timed complementary PWM with programmable dead-band, perfect for driving half-bridges in LED drivers. The PIC16F1719T-I/MV's 32 MHz core and 28 KB Flash allow continuous color-mix loops, DMX512 reception over UART and per-channel temperature compensation. The on-chip op-amps can amplify a thermistor for thermal foldback without an external analog IC. Use the COG outputs to gate the high-side and low-side MOSFETs directly, then use ADC2 (10-bit) to read LED current via a shunt resistor. This eliminates an LED-driver IC and a temperature sense amplifier from the BOM, dropping component count by 3-5 parts per channel.

Industrial Sensor Signal Conditioning
The on-chip operational amplifiers of the PIC16F1719T-I/MV allow direct conditioning of 4-20 mA loops, Wheatstone bridges and thermocouples. With 28 KB Flash and 2 KB RAM, the device can run calibration tables and Modbus RTU framing simultaneously. Use the 10-bit ADC with computation (ADC2) to perform hardware-averaged conversions without CPU load, and the CLC to implement window-comparator trip logic. The PPS function lets UART, SPI and PWM be mapped to any I/O, simplifying PCB layout when routing isolated industrial interfaces. Typical circuit: op-amp in instrumentation configuration feeding the ADC, with CLC triggering an alert GPIO when thresholds are crossed.

IoT Sensor Nodes and Battery Monitoring
The PIC16F1719T-I/MV's XLP (eXtreme Low Power) technology and 32 MHz performance let it act as the controller for battery-powered IoT nodes, periodically waking from sleep to read sensors, transmit over UART/SPI to a radio module, and returning to sleep. The on-chip 10-bit ADC monitors battery voltage with hardware averaging, while the op-amps condition current-sense shunts for coulomb counting. Core Independent Peripherals (CLC, NCO, Zero-Cross Detect) allow wake-up on external events without CPU intervention, minimizing average current. Use 2 KB RAM for buffering Modbus or simple BLE controller stacks before transmission, and the 28 KB Flash for application logic and over-the-air update bootloaders.

Consumer Appliance Control
In white goods and small appliances, the PIC16F1719T-I/MV provides the motor-control timing (via COG and PWM), user-interface scanning (via PPS-mappable I/O) and sensor conditioning (via on-chip op-amps) in a single chip. With 28 KB Flash it can hold a complete UI state machine plus diagnostic logs. The CLC implements hardware button debouncing and over-current protection without CPU load. The 40-pin UQFN package is small enough to fit alongside a 3-phase inverter in washing machines, dishwashers and induction cooktops. Use the Zero-Cross Detect peripheral for AC line-voltage zero-crossing synchronization to drive TRIACs efficiently.

Power Conversion and SMPS Secondary-Side Control
The PIC16F1719T-I/MV can serve as the secondary-side controller in isolated switch-mode power supplies, providing digital PWM generation, output voltage/current sensing, and housekeeping communications. The COG peripheral produces the timing signals for synchronous rectifiers with programmable dead-band, while the op-amps condition current-mode signals. The 10-bit ADC samples Vout at high rate using ADC2 hardware accumulation. PPS lets the UART be routed to the opto-isolated feedback path. With 28 KB Flash, the device can implement adaptive loop compensation and PMBus telemetry alongside basic regulation. Industrial -40C to +85C operating range suits most PSU environments.

Automotive Body and Interior Modules
While the PIC16F1719T-I/MV is the industrial (-40C to +85C) grade, its feature set (CLC, COG, NCO, PPS, on-chip op-amps) is well-suited to body-electronics functions in non-safety-critical automotive applications: interior lighting drivers, seat-position memory, mirror control, and HVAC blend-door actuators. The op-amps can read potentiometer positions on motorized slides, while the COG drives the H-bridge PWM. Use the CLC to implement window-comparator limit detection without waking the CPU. For safety-critical automotive applications the AEC-Q100 qualified PIC16F1719T-I/MVVAO grade should be substituted; refer to the device family data sheet for qualified variants.

Ghi chú thiết kế
The 40-pin UQFN package has an exposed thermal pad on the underside that must be soldered to a PCB land of at least the same area to meet the thermal performance published in the datasheet. Per IPC-7351, the UQFN-40 land pattern uses 0.5 mm pitch pads. Decoupling: place a 100 nF X7R ceramic as close as possible to each VDD pin, with a shared 10 uF bulk capacitor near the package. Keep the exposed-pad via array on a 1.0 mm grid using 0.3 mm via holes to balance thermal dissipation and soldering yield.
PIC16F1719T-I/MV requires a stable VDD ramp. Add a 10 kohm pull-up to MCLR and place a 100 nF capacitor directly on MCLR to VSS to ensure proper reset behavior. For battery-powered applications using XLP sleep modes, verify the IQ current spec from Microchip datasheet DS40001700D before calculating battery life. Estimated: at 32 MHz active and 1.8V VDD, active current is approximately 4 mA; at 32 kHz LFINTOSC sleep it drops to a few microamps. Always use the BOR (Brown-Out Reset) feature enabled in configuration bits for unattended industrial applications.
A common design pitfall is leaving PPS unlocked or assigning conflicting peripheral mappings - this can cause non-functional GPIOs at first power-up. Always explicitly configure PPS input/output registers at startup. Another pitfall is misconfiguring the ADC: the 10-bit ADC reference voltage defaults to VDD; for accurate readings of low-voltage sensors use the external VREF+ pin. Finally, when migrating from PIC16F1719-I/MV (tray) to the T/MV tape-and-reel variant, confirm reel quantities match the SMT line's feeder setup - the UQFN-40 'T' ships on 13-inch reels with 3300-piece standard quantity.
