MPN： PIC16F1619T-I/SS ✓ 啟用中PIC16F1619T-I/SS 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of programmable peripherals. The PIC16 family sits at the mid-range of Microchip's 8-bit portfolio, using a 14-bit instruction word with a modified Harvard architecture, designed for low power and deterministic interrupt response. The PIC16F1619 is part of the PIC16(L)F161x family of enhanced mid-range XLP MCUs, tailored for Functional Safety (FuSa) compatible applications, which means the device integrates fault-detection peripherals such as a CRC, hardware limit timer, and windowed watchdog that simplify IEC 61508 SIL-1 design-ins.
Key features include 14KB (8K x 14) Flash, 1KB RAM, 32MHz internal oscillator, 10-bit ADC with computation, Zero-Cross Detect (ZCD) for TRIAC and SSR control, Complementary Waveform Generator (CWG) for synchronous MOSFET driving, Configurable Logic Cells (CLC) for hardware glue logic, and four 16-bit timers. The device supports 1.8V to 5.5V operation (PIC16F1619 'F' variant), with industrial -40C to +85C temperature range, and is available as 'T-I/SS' in tape-and-reel packaging.
Technically, the PIC16F1619 uses a 14-bit wide instruction path with a 16-level hardware stack, offering fast context save/restore. Its XLP technology targets nanoWatt sleep currents with active mode currents in the microampere range, ideal for battery-powered designs. The FuSa-oriented peripherals (CRC scan, hardware limit timer, windowed WDT) reduce software overhead in safety-critical loops.
Typical applications include small BLDC/PMSM motor control with integrated CWG and ZCD, white-goods and appliance control, LED lighting drivers, sensor signal conditioning, and IEC 61508 functional-safety designs. The 20-SSOP footprint is also well suited for compact IoT nodes.
When designing with this MCU, mind the supply decoupling (100nF + 10uF bulk at VDD), keep MCLR pull-up above 4.7 kohm for noise immunity, and reserve one CLC for ZCD blanking if you are driving AC loads. The PIC16F1619T-I/SS is pin-compatible within the PIC16F161x family for board-level reuse.

典型應用
PIC16F1619T-I/SS 適用於 6 應用s: Small BLDC and PMSM Motor Control, Functional Safety (IEC 61508 SIL-1) Appliance Control, AC Load and TRIAC/SSR Dimming Control, Battery-Powered IoT Sensor Nodes, White Goods and Appliance User Interface, Automotive Body and Interior Modules.
Small BLDC and PMSM Motor Control
The PIC16F1619T-I/SS is engineered for small BLDC and PMSM motor control loops thanks to its integrated Zero-Cross Detect (ZCD), Complementary Waveform Generator (CWG), and four 16-bit timers. ZCD senses the back-EMF zero crossing of a motor phase without extra analog hardware, while the CWG outputs complementary PWM pairs with programmable dead-time - critical for synchronous MOSFET bridges that would otherwise require a dedicated gate driver. The 32 MHz core (8 MIPS) executes field-oriented control loops in software with enough margin for trapezoidal commutation of fans, small pumps, and ceiling-fan BLDCs. The 1.8-5.5 V VDD range lets the same board design run from a single 18650 Li-ion cell or a 5 V USB rail, and XLP nanoWatt sleep currents below 1 uA keep standby battery drain negligible in always-on appliances.

Functional Safety (IEC 61508 SIL-1) Appliance Control
Functional Safety designs in white goods and HVAC controllers benefit from the PIC16F1619's built-in CRC scan engine, hardware limit timer, and Windowed Watchdog Timer (WWDT). The CRC performs cyclic background memory scans to detect Flash bit errors, while the hardware limit timer independently enforces a maximum actuation duration for safety-critical outputs (heaters, valves, pumps) without CPU intervention. The WWDT triggers a system reset if the firmware fails to service it within a precise window, catching both stuck-too-long and reset-too-fast fault modes. Combined with the Configurable Logic Cell (CLC) for hardware-level interlocking of safety outputs, the PIC16F1619T-I/SS cuts the firmware complexity for IEC 61508 SIL-1 implementations, and Microchip publishes FMEDA and safety manuals to streamline certification.
推薦
AC Load and TRIAC/SSR Dimming Control
Zero-Cross Detect (ZCD) on the PIC16F1619T-I/SS lets the MCU detect AC mains zero crossings without an optocoupler or external comparator, dramatically simplifying phase-angle or zero-cross TRIAC and SSR dimmer designs. The internal ZCD module drives an interrupt that the firmware uses to schedule TRIAC gate pulses, while the CLC cell can implement hardware-level blanking to suppress noise-induced false triggers. Running from a capacitive-dropper supply directly off the AC line, the PIC16F1619's 1.8-5.5 V VDD and nanoWatt XLP modes keep standby power below 100 mW - critical for EU Ecodesign and ENERGY STAR requirements. The 32 MHz CPU executes soft-start, soft-end, and dimming-curve algorithms with cycle-by-cycle timing precision.

Battery-Powered IoT Sensor Nodes
Battery-powered IoT sensor nodes benefit from the PIC16F1619T-I/SS's XLP nanoWatt technology, which delivers sub-microampere sleep currents and active-mode currents in the hundreds of microamperes range at 1 MHz. The 14 KB Flash fits Zigbee PRO, BLE stack front-ends, or LoRaWAN Class A device drivers, and the 1 KB RAM is sufficient for small sensor buffers without external memory. The integrated 10-bit ADC with computation (averaging, threshold compare) eliminates the need for a separate analog front-end IC, reducing BOM cost and board area. The Configurable Logic Cell (CLC) can hardware-debounce a wake-up push-button without waking the CPU, preserving battery life over multi-year deployments.
推薦
White Goods and Appliance User Interface
The PIC16F1619T-I/SS handles user-interface logic in washing machines, dishwashers, ovens, and refrigerators by combining capacitive-touch-ready I/O with the Configurable Logic Cell (CLC) for hardware debouncing and rotary-encoder decoding. Its four hardware timers drive LED indicators, buzzer PWM, and segment-LCD multiplex waveforms without CPU load, leaving the 8 MIPS core free for the appliance's main state machine and communication stack (UART to a Wi-Fi or BLE module). The 1.8-5.5 V VDD range lets the board run from a single 3.3 V or 5 V rail, and the SSOP-20 footprint fits behind a 7-segment display module. Microchip supplies reference firmware and application notes for capacitive touch and segment-LCD bias generation on this family.
推薦
Automotive Body and Interior Modules
The PIC16F1619T-I/SS suits automotive body-electronics modules such as interior lighting controllers, seat-adjustment keypads, and HVAC blend-door actuators. Its -40C to +85C industrial temperature range covers cabin environments, and the Windowed Watchdog Timer catches transient firmware lockups caused by EMI on long wiring harnesses. The ZCD and CWG can drive LED strings or small brushed DC motors without external gate drivers, and the CRC engine performs background Flash integrity checks mandated by ISO 26262-derived workflows. The SSOP-20 footprint is well suited to the space-constrained PCB layouts inside door modules and center-stack consoles.

設計說明
Place a 100 nF X7R decoupling capacitor within 5 mm of the VDD pin (pin 16) and a 10 uF X5R bulk capacitor on the same rail. The PIC16F1619's analog peripherals (ADC, ZCD) share the VDD rail and can introduce 1-2 LSB noise if the bulk decoupling is omitted. For battery-powered designs with long sleep intervals, the 10 uF bulk capacitor doubles as a reservoir that prevents VDD droop during wake-up transients. Estimated: with the XLP sleep current of approximately 50-100 nA and a 10 uF bulk cap, VDD ripple during a 10 ms wake-up at 32 MHz stays below 30 mV - well within the ADC's 1 LSB at 3.3 V.
The SSOP-20 footprint has a thermal pad but no exposed pad - the package dissipates heat through the SSOP leads. The estimated theta_JA of the SSOP-20 is approximately 90 C/W (estimated based on similar 20-pin SSOP packages). For motor-control designs that switch high-current loads, keep ground-return currents away from the analog pins by partitioning the PCB into digital, analog, and power sections joined at a single-point ground star under VSS pin 7. Place the ICSP header (PGC/PGD on RA4/RA5) on the same side of the board as the MCU to minimize stub lengths.
Do not connect MCLR (RA3/MCLR, pin 3) directly to VDD - a 4.7 kohm to 10 kohm pull-up is mandatory for noise immunity and in-circuit serial programming (ICSP). Forgetting the MCLR pull-up is the single most common reason for ICSP programming failures. Additionally, the ZCD pin (RB0 on this package) requires the ZCD peripheral to be enabled in CONFIG words - it does not function as a normal GPIO if left in default reset state. Finally, the WWDT must be enabled with a window value; using WWDT as a regular WDT (no window) defeats its safety purpose.
For AC-mains ZCD designs, the ZCD input requires an external series resistor of at least 1 kohm to limit surge current per the datasheet. Add a 5.6 V Zener clamp at the ZCD pin to protect against transients on the AC line. The CWG output pins (RA6/RA7 in this SSOP-20 layout) toggle up to 32 MHz in complementary mode - route them as short differential traces, and add 22 ohm series resistors to dampen ringing when driving external MOSFET gates. Estimated: a 5 cm trace un-terminated can ring up to 30% of VDD at 32 MHz, exceeding typical MOSFET gate-drive ratings.
