PIC16F1619T-I/SO - 8-bit MCU, 14KB Flash, 32MHz, 20-SOIC | Microchip
MPN: PIC16F1619T-I/SO ✓ Hoạt độngPIC16F1619T-I/SO Tóm tắt
Key features include a 10-bit ADC, Capture/Compare/PWM (CCP), 24-bit Signal Measurement Timer (SMT), Zero-Cross Detect, and the eXtreme Low Power (XLP) technology that characterizes this family. The -I temperature grade suffix denotes industrial -40C to +85C operation, while the -T suffix indicates tape-and-reel packaging for high-volume assembly. The 20-pin SOIC footprint provides a familiar, breadboard-friendly and reflow-solderable form factor used across the PIC16F1xxx family.
Technically, the PIC16F1619 belongs to Microchip's enhanced mid-range PIC16 core with a 14-bit instruction word, hardware multiplier, and a peripheral pin-select (PPS) block that remaps digital I/O to most device pins. The 24-bit SMT can capture time-of-flight, frequency, period, and pulse-width measurements with sub-microsecond resolution, while the Zero-Cross Detect block enables AC-line synchronous triggering for TRIAC or SSR control in motor and lighting applications. Internal oscillator accuracy is trimmed at the factory to within ±1% typical.
Typical applications include small BLDC and stepper motor control, ceiling-fan and HVAC triac-based phase-angle control, white-goods and appliance user-interface boards, LED lighting drivers with dimming, and general-purpose 8-bit embedded control replacing discrete logic. Functional-safety features support IEC 60730 Class B household appliance requirements, where the MCU performs self-diagnostics on clock, supply, and program-flow integrity.
When designing with this part, allocate 4 bytes of the configuration word for oscillator and watchdog settings and reserve a PPS lock sequence before reassigning I/O. For motor-drive boards, route the Zero-Cross Detect input through a 100k series resistor and a 100V TVS clamp to meet surge requirements. Verify the trailing 'T' in the MPN specifies the tape-and-reel quantity you need for production.

Ứng dụng tiêu biểu
PIC16F1619T-I/SO phù hợp cho 6 Áp dụngs: Small BLDC and PMSM Motor Control, IEC 60730 Class B Household Appliances, AC-Line Phase-Angle and TRIAC Dimming, User-Interface and HMI Boards, LED Lighting Drivers with Dimming, General-Purpose 8-bit Embedded Control.
Small BLDC and PMSM Motor Control
The PIC16F1619T-I/SO fits 1-shunt or 3-shunt sensorless BLDC motor drive boards thanks to its 32 MHz core executing FOC loops in 8 MIPS, the 24-bit SMT capturing Hall-sensor or BEMF edges with sub-microsecond resolution, and the 10-bit ADC sampling phase currents within 2 us conversion windows. The 14 KB Flash accommodates Microchip's AN1078 sensorless FOC library (typical 9-11 KB), leaving room for application code. Industrial -40C to +85C operation tolerates motor bay environments, while XLP sleep modes cut standby current under 50 nA - useful for battery-backed ceiling fans and appliance pumps. Connect the CCP/PWM outputs to gate-driver inputs and route Zero-Cross Detect to the AC mains interface for combined motor-and-line control.

IEC 60730 Class B Household Appliances
The PIC16F1619T-I/SO carries Functional Safety (FuSa) hardware that lets white-goods designers meet IEC 60730 Class B self-test requirements for washing machines, dryers, induction cooktops, and dishwashers. The on-chip clock-monitor, WDT window, and Flash CRC peripheral run Class B self-test routines automatically, while the 14 KB Flash holds both the application and the safety-library stubs. Zero-Cross Detect synchronizes TRIAC firing to the AC mains zero crossing for safe phase-angle control of heater elements. Operate the part at 5V from a 3.3V LDO plus diode-OR backup to ride out brown-outs in mains-side appliance boards.

AC-Line Phase-Angle and TRIAC Dimming
The PIC16F1619T-I/SO's integrated Zero-Cross Detect block synchronizes to the AC mains zero crossings and triggers the on-chip CCP modules to fire a TRIAC or opto-isolated SSR after a programmed phase delay, enabling phase-angle dimming for lamp banks, ceiling fans, and heater banks. The 32 MHz core computes firing angles at 60 Hz/50 Hz line frequency with sub-microsecond accuracy, while the 10-bit ADC reads a potentiometer or 0-10V dim signal and converts it to firing delay in real time. The 14 KB Flash holds custom dimming curves (logarithmic, square-law) and the 1 KB SRAM buffers ramping state. Industrial temperature grade covers enclosed fixture environments, and XLP sleep modes save power when the lamp is off.

User-Interface and HMI Boards
The PIC16F1619T-I/SO serves as the master MCU on a white-goods or appliance user-interface board, scanning capacitive-touch pads, rotary encoders, and 7-segment or TFT LCD displays while communicating with a host power-stage MCU via UART or I2C. Its Peripheral Pin Select (PPS) block remaps UART, I2C, and SPI to any RPn pin, simplifying PCB routing when a display connector is relocated. The 10-bit ADC reads NTC thermistors for temperature feedback, and the 24-bit SMT measures long press durations and button-debounce intervals. Running at 32 MHz, the core drives a 4-line character LCD with 5x8 font without external controller ICs, and XLP sleep keeps standby current negligible.

LED Lighting Drivers with Dimming
The PIC16F1619T-I/SO implements constant-current LED drivers by combining its 10-bit ADC for current-sense feedback, its CCP modules for PWM dimming at up to 32 kHz without flicker, and the 24-bit SMT for precise DALI-2 or 0-10V dim timing. The 14 KB Flash fits DALI-2 IEC 62386 protocol stacks while leaving headroom for fixture-specific calibration tables. The 2.5V-5.5V supply range supports both battery-powered and mains-fed driver topologies. Place the part near the LED strings with 100V-rated PCB isolation and route the ADC reference through a low-TCXO buffer to maintain brightness accuracy across temperature.

General-Purpose 8-bit Embedded Control
The PIC16F1619T-I/SO serves as a general-purpose 8-bit controller in sensor hubs, simple protocol bridges, battery chargers, and IoT edge nodes where Cortex-M0+ would be overkill. The 32 MHz CPU executes UART bootloader, I2C slave, and basic PID control loops within 14 KB Flash, while the 1 KB SRAM handles 8-byte-deep protocol buffers. Peripheral Pin Select remaps digital functions to any I/O pin, freeing PCB layout from rigid signal constraints. The industrial -40C to +85C temperature grade supports outdoor enclosures, and the XLP sleep modes extend battery life in wireless sensor nodes to multi-year runtime. Add a 32.768 kHz crystal for RTC accuracy where needed.

Ghi chú thiết kế
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin (pin 18) and a 10 uF bulk capacitor on the same supply rail. The PIC16F1619T-I/SO draws 5-8 mA active at 32 MHz and under 50 nA in XLP sleep; verify the LDO can source the worst-case active current including ADC sampling bursts.
Reserve the ICSPDAT/ICSCLK pins (RB6/RB7 on 20-SOIC) for in-circuit serial programming access - do not place small passives within 2 mm of these pins or in-circuit programming will require board rework. Route MCLR/VPP (pin 1) through a 10 kohm pull-up to VDD with a 100 nF capacitor to ground for proper reset behavior.
Always issue the PPSLOCK unlock sequence before reassigning Peripheral Pin Select mappings at runtime, otherwise writes to RPINRx/RPORx registers are silently ignored. When migrating code from PIC16F1613 (smaller Flash) to PIC16F1619, the additional register banks require updating the BANK_SEL macros in your linker script or you will read stale SFR values.
For Zero-Cross Detect input on the AC mains, place a 100 kohm series resistor immediately at the pin and a 100 V bidirectional TVS to ground within 5 mm to clamp line transients. Keep the trace length under 10 mm to avoid capacitive pickup that can shift the zero-crossing trigger by hundreds of microseconds, breaking TRIAC timing.
Thông tin tuân thủ
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified (industrial grade only). Functional Safety (FuSa) peripherals support IEC 60730 Class B but the part itself is not automotive-qualified - use PIC16F1619-E/SO for extended-temperature industrial applications.
