PIC16LF1619-I/P Übersicht
What is an 8-bit PIC microcontroller? An 8-bit PIC is a RISC-based microcontroller from Microchip Technology using a Harvard architecture with separate program and data buses. PIC microcontrollers occupy the broader hierarchy of microcontrollers and embedded processors within integrated circuits, and are widely adopted for low-power, deterministic real-time control in industrial, automotive, and consumer products.
Key features include 14 KB self-programmable Flash, 1 KB SRAM, 256 bytes EEPROM, up to 17 I/O pins, peripheral pin select, 10-bit ADC with computation, and Core Independent Peripherals (CIPs) such as ZCD, CWG, and SMT. The device also integrates an internal 32 MHz oscillator and supports In-Circuit Serial Programming (ICSP).
The PIC16LF1619-I/P uses a 14-bit instruction word RISC core capable of executing most instructions in one cycle. The XLP designation indicates optimized low-power operation with sleep currents in the nanoampere range, multiple power-managed operating modes, and peripheral activity monitors that wake the core on external events without software intervention.
Typical applications include small-DC-motor control with back-EMF sensing using ZCD, LED lighting control, consumer white goods, sensor conditioning, and low-power IoT nodes. The 20-pin DIP package is particularly suited for prototyping and through-hole manufacturing flows.
When designing, place a 0.1 µF decoupling capacitor close to VDD and route the analog VDD (AVDD) reference carefully when using the ADC. ICSP requires dedicated ICSPCLK/ICSPDAT pins which must be accessible even in the final PCB layout.

Typische Anwendungen
PIC16LF1619-I/P ist geeignet für 6 Anwendungs: Small-DC-Motor Control, AC Line Zero-Cross Sensing, Battery-Powered IoT Sensor Nodes, Consumer White Goods Control, LED Lighting Control, Touch & Capacitive Sensing Front Panels.
Small-DC-Motor Control
The PIC16LF1619-I/P is ideal for small-DC motor control because it integrates Zero-Cross Detection (ZCD), Complementary Waveform Generator (CWG), 24-bit Signal Measurement Timer (SMT), 10-bit ADC with computation, and PWM — all Core Independent Peripherals that execute in hardware without CPU intervention. The 32 MHz CPU provides 8 MIPS throughput for closed-loop control algorithms, while the XLP low-power architecture keeps battery drain minimal during standby. Designers wire the motor H-bridge feedback to the ZCD pin for back-EMF sensing, use SMT for accurate RPM measurement via period capture, and let CWG generate complementary drive waveforms with hardware dead-band. The 20-pin PDIP package suits through-hole prototype and small-batch appliance manufacturing.

AC Line Zero-Cross Sensing
Zero-cross detection of an AC mains waveform is a primary use case for the PIC16LF1619-I/P, where the integrated ZCD peripheral operates directly off a 120 V / 240 V line via a current-limiting resistor without external op-amps or comparators. The ZCD pin triggers an interrupt on each zero crossing, allowing the MCU to control triac-fired loads (heaters, lamps, solenoids) with minimal EMI. Combined with the 32 MHz internal oscillator and hardware CWG, designers can build dimmers, motor-speed controllers, and synchronous solid-state relays. The XLP sleep current under 50 nA makes battery-backed smart-switch products feasible. The 20-pin PDIP footprint simplifies connection to mains-isolation barrier boards.
Empfohlen
Battery-Powered IoT Sensor Nodes
Battery-powered IoT sensor nodes benefit from the PIC16LF1619-I/P because of its nanoWatt XLP technology, which provides sub-µA sleep currents with peripheral wake-on-event operation. The 14 KB Flash comfortably hosts wireless protocol firmware, while 1 KB SRAM buffers sensor data before transmission. The 1.8 V to 3.6 V supply range directly supports 3.3 V coin-cell or 2×AA battery operation. SMT peripheral can measure pulse-width sensor signals with 24-bit precision for flow meters or pulse-output sensors. ADC-with-computation automates averaging and threshold comparison without CPU wake-ups. The 20-pin PDIP package is convenient for through-hole prototype boards before reflow-ready QFN migration for volume production.
Empfohlen
Consumer White Goods Control
Consumer appliances like washing machines, dishwashers, and refrigerator controllers fit the PIC16LF1619-I/P's feature set: 14 KB Flash for state-machine and user-interface code, ZCD for AC line synchronization, CWG for motor-drive waveforms, and PWM for valve/relay control. The 32 MHz speed delivers deterministic real-time response to keypad presses and over-temperature safety events. Wide 1.8 V to 3.6 V operating tolerance handles brown-out and load-dump events typical of compressor-driven appliances. The industrial -40 °C to +85 °C temperature grade supports unheated appliance compartments. Designers use the 10-bit ADC to read thermistor inputs for closed-loop temperature control with hardware threshold interrupts.
Empfohlen
LED Lighting Control
LED lighting drivers benefit from the PIC16LF1619-I/P's PWM, CWG, and ADC-with-computation peripherals. CWG generates high-resolution dimming waveforms synchronized to AC-line zero crossings via ZCD, supporting phase-cut dimmer emulation and flicker-free dimming down to <1 % duty cycle. The 10-bit ADC reads ambient light sensors for closed-loop daylight harvesting, and ADC-with-computation performs automatic brightness averaging, reducing CPU wake events. XLP operation supports battery-backed wireless dimmer remotes with multi-year coin-cell life. The 20-pin PDIP footprint is ideal for retrofit-lamp driver boards where through-hole assembly is preferred. Hardware CRC supports DMX-512 or DALI-style lighting-protocol error checking.
Empfohlen
Touch & Capacitive Sensing Front Panels
Capacitive touch-button front panels for kitchen appliances, industrial controls, and consumer electronics leverage the PIC16LF1619-I/P's mTouch peripheral, Core Independent Peripherals, and 14 KB Flash for robust touch firmware. The 32 MHz CPU resolves mTouch measurements in real time, and the 10-bit ADC supports proximity and slider scanning. Hardware CIPs free CPU bandwidth for communication stacks (I²C, SPI, UART). The 1.8 V to 3.6 V range and XLP sleep keep battery-powered remote controls alive for years. The 20-pin PDIP package supports prototype front-panel boards; migration to QFN is straightforward for high-volume products.

Wichtigste Unterscheidungsmerkmale
- Integrates Zero-Cross Detection (ZCD) peripheral for AC-line applications (vs. PIC16LF1618-I/P)
- Includes 24-bit Signal Measurement Timer (SMT) peripheral (vs. PIC16LF15325-I/P)
- Larger program memory at lower voltage operation than F-variant (vs. PIC16F1619-I/P)
Designhinweise
Place a 0.1 µF ceramic decoupling capacitor within 3 mm of each VDD pin (pin 16 and pin 20) with a wide, short trace to the nearest VSS pin (pin 7 and pin 19). For analog applications using AVDD, follow the datasheet's AVDD/VREF layout guidance to isolate analog and digital grounds to a single-point star ground at the VSS pins. Use a bulk 10 µF tantalum or ceramic capacitor at the board's power entry. The 1.8 V minimum operating voltage means a discharged 2×AA battery (2.0 V) still operates reliably; below 1.8 V the BOR holds the MCU in reset.
Reserve dedicated access to ICSPCLK (RB6/pin 9) and ICSPDAT (RB7/pin 8) on the PCB, even in production layouts, because Microchip recommends ICSP-capable programming access for field firmware updates. If the design uses these pins for I/O, route them to test points or a programming header. Keep analog traces (RA0-RA5) short and away from switching digital lines to minimize ADC sampling noise; use a ground guard ring around the AN0/AN1 capacitive-touch pins.
Do not drive the MCLR pin (RA3/pin 3) low in-circuit unless performing a reset; an unintended low causes continuous reset. Configure unused I/O pins as outputs driving low to minimize sleep current. When using the 32 MHz internal oscillator, ensure VDD is stable above 1.8 V before releasing MCLR — brown-out below 1.8 V triggers BOR, but marginal voltage may cause unstable code execution. Verify PPS (Peripheral Pin Select) mappings in the APFCON registers at startup if remapping pins from defaults.
The PIC16LF1619-I/P operates from -40 °C to +85 °C (Industrial). Diode-controlled internal current peaks draw operating hours of derating above ambient. Estimated: continuous 32 MHz CPU execution at 3.3 V draws ~3 mA, producing ~10 mW power dissipation — well within the 20-pin PDIP thermal envelope without a heatsink. Closed-package DIP junction-to-ambient thermal resistance is typically 70 °C/W for socketed DIP; verify with the Microchip family thermal application note AN243 for production thermal budgets.
