PIC16LF1619-E/SS 概述
An 8-bit microcontroller (MCU) is a single-chip computer based on an 8-bit data bus architecture, optimized for cost-sensitive, deterministic real-time control. Within the broader hierarchy, the PIC16LF1619 sits under the PIC16F family → PIC16F1xxx enhanced mid-range core → 8-bit MCU → microcontroller → embedded processor → semiconductor. The 'LF' prefix indicates the wide-voltage 'F' process variant supporting operation down to 1.8 V, while the 'E' temperature grade denotes an extended industrial range of -40 °C to +125 °C. SSOP-20 packages balance I/O count with compact board footprint.
Key features include 32 MHz internal oscillator (8 MIPS instruction throughput), 18 I/O pins, 1.8 V to 3.6 V VDD range, 10-bit ADC with computation, Zero-Cross Detect for AC line sensing, Windowed WDT for ASIL-B-ready firmware safety, and hardware CRC engine. The 14 KB Flash is self-programmable and supports dual-operand reads. Core-independent peripherals (CIPs) such as the Configurable Logic Cell (CLC), NCO, and 24-bit Signal Measurement Timer (SMT) allow hardware-level event handling without CPU intervention.
Typical applications include BLDC/PMSM small motor control (fans, pumps, appliance drives), LED lighting drivers, IoT edge sensor nodes, AC mains zero-crossing detection for solid-state relays (SSR/TRIAC driving), consumer white goods, and battery-powered instrumentation where the XLP nanoWatt XLP sleep modes extend coin-cell lifetime.
Design tip: use the ZCD output directly to trigger a hardware timer for mains-zero-cross TRIAC firing, and place a 100 nF + 10 µF decoupling pair within 3 mm of VDD/SS pins to keep ADC noise low. Application note AN2017 (microchip.com) covers the CLC + SMT pairing for sensorless BLDC commutation on this exact die.

典型应用
PIC16LF1619-E/SS 适用于 6 应用s: BLDC / PMSM Small Motor Control, AC Mains Zero-Cross Dimming (TRIAC / SSR), Battery-Powered IoT Sensor Node, White Goods / Home Appliance Control, Automotive Body Electronics, Industrial Sensor Transmitter (4-20 mA / Modbus).
BLDC / PMSM Small Motor Control
The PIC16LF1619-E/SS fits sensorless BLDC and small PMSM motor control because its on-chip Zero-Cross Detect (ZCD), 24-bit Signal Measurement Timer (SMT), and Configurable Logic Cells (CLC) close the commutation loop in hardware, freeing the 32 MHz CPU (8 MIPS) for upper-layer torque and speed control. With 14 KB Flash, BLDC reference code from Microchip AN1078/AN2017 fits without external firmware. A 3-phase 6-step commutation loop can be executed in under 25 µs at 32 MHz. The XLP nanoWatt sleep modes drop system current below 20 nA in standby, ideal for battery-backed appliance drives.
推荐
AC Mains Zero-Cross Dimming (TRIAC / SSR)
For phase-control dimmers and solid-state relay controllers, the PIC16LF1619-E/SS directly senses the AC mains zero-cross event through its integrated ZCD peripheral, eliminating the external optocoupler + comparator front-end used on legacy 8-bit MCUs. The ZCD output triggers a 24-bit SMT timer that schedules TRIAC gate pulses with sub-microsecond accuracy, supporting leading-edge and trailing-edge dimming topologies. The hardware CRC engine validates command packets received over UART from a lighting controller, and 14 KB Flash accommodates the dimming curve library.
推荐
Battery-Powered IoT Sensor Node
The PIC16LF1619-E/SS in a 20-pin SSOP delivers a 1.8 V to 3.6 V operating range and sub-20 nA typical sleep current, so two AA alkaline cells or a CR2032 coin cell can run a sensor node for years. Its 10-bit ADC with computation reads thermistor, photodiode, or PIR outputs; the hardware CRC engine authenticates LoRa/Wi-Fi packets without CPU overhead. Core-independent peripherals (CLC, NCO) keep the MCU in Sleep until an event wakes it. The 14 KB Flash holds BLE/Zigbee stack fragments or LoRaWAN node firmware for low-rate telemetry.
推荐
White Goods / Home Appliance Control
The PIC16LF1619-E/SS -E grade supports -40 °C to +125 °C operation, which is mandatory for kitchen and laundry appliances where internal ambient temperatures routinely exceed 85 °C. Its 18 I/O pins drive relays, triac optos, keypads, and 7-segment displays without external I/O expanders. The Windowed Watchdog Timer (WWDT) catches runaway firmware in safety-critical functions such as door-lock interlocks and heater cutoffs. Microchip Class B safety libraries (AN1229) target this family directly, reducing IEC 60730 certification time for home appliances.
推荐
Automotive Body Electronics
The PIC16LF1619-E/SS -E grade temperature range and 32 MHz CPU with 8 MIPS throughput suit body-electronics modules such as seat controllers, mirror adjusters, and LED interior lighting. Although the part is not AEC-Q100 qualified, Microchip offers the PIC16F1619-E/SS equivalent in PPAP form for selected customers. The 10-bit ADC reads potentiometers and switches, while the PWM/CCP modules drive LED backlights with smooth 16-bit resolution. The hardware CRC engine validates LIN-bus messages per ISO 17987.
推荐
Industrial Sensor Transmitter (4-20 mA / Modbus)
For loop-powered industrial sensors, the PIC16LF1619-E/SS delivers 10-bit ADC measurement accuracy adequate for pressure, level, or flow transmitters. Its 1.8 V to 3.6 V operating range lets it run from a 3.3 V LDO fed by the 4-20 mA loop, while sub-20 nA Sleep current extends loop-compliance voltage headroom. The 32 MHz core executes floating-point scaling and linearization at high update rates, and the UART/USART peripheral interfaces directly to a Modbus RTU transceiver. The hardware CRC engine checks Modbus frame integrity per IEC 60870.

- Lower VDD operating range (1.8 V vs 2.3 V) supports depleted 2x AA battery operation （对比 PIC16F1619-E/SS)

设计说明
Place a 100 nF + 10 µF ceramic decoupling pair within 3 mm of the VDD (pin 5) and VSS (pin 6) pads to suppress switching-noise-induced ADC errors. The on-chip 16 MHz HFINTOSC has a 1% typical accuracy after calibration but drifts up to 2% across temperature; for UART baud rates above 115 200 bps, switch to the 32 MHz HFINTOSC or a 4x PLL on the 8 MHz source, and verify framing with the on-chip DMT peripheral. Estimated: at 32 MHz and 3.3 V, IDD ≈ 5 mA active and < 20 nA in Sleep per DS40001826 typical curves.
The 20-pin SSOP (5.30 mm body) has 0.65 mm pitch pads — design the land pattern per IPC-7351 nominal with a 0.45 mm pad width and 0.40 mm aperture for production solder paste stencils. Keep all traces < 25 mm/4.5 ns to maintain signal integrity on ICSPDAT/ICSPCLK (RA0/RA1). For EMI-sensitive motor-control boards, route RC0–RC7 PWM outputs together on one PCB layer to balance edge rates and avoid ground-bounce coupling into the ADC reference.
The MCLR pin (RA3, pin 1) doubles as the ICSP programming voltage input; do not drive it directly with a 5 V logic level from a 5 V system when VDD = 3.3 V — this can back-power the regulator through internal ESD diodes. Use a current-limit resistor (≥ 10 kΩ) on MCLR if it is shared with a reset source. Also, the ZCD input is sensitive to fast transients; for 230 V AC mains applications, place a 1 MΩ + 100 kΩ resistive divider and 100 pF filter directly at the ZCD pin per AN2017 reference design.
