PIC16F1619-E/P 概述
A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash program memory plus SRAM and EEPROM), and programmable I/O peripherals. Within the broader hierarchy, MCUs sit inside the embedded computing category, alongside microprocessors and DSPs; the PIC16 family is Microchip's mid-range 8-bit family, sitting between the baseline PIC10/PIC12/PIC16F and the high-performance PIC18/PIC24 families. The PIC16F1619 specifically targets applications that need signal-generation or motion-control peripherals (24-bit SMT, Zero-Cross Detect, CCP, Angular Timer) plus a 10-bit ADC, all in a small 14/20-pin footprint.
Key features include 14KB (8K x 14) self-programmable Flash program memory, 1KB SRAM, and on-chip peripherals such as a 10-bit ADC with Computation (ADC2), Capture/Compare/PWM (CCP), 24-bit Signal Measurement Timer (SMT), Zero-Cross Detect (ZCD), and the Peripheral Pin Select (PPS) module. The device supports up to 32 MHz internal oscillator operation, and the XLP (eXtreme Low Power) variant is qualified for Functional Safety (FuSa) applications per the PIC16F16XX family roadmap. The wide 1.8V-5.5V VDD range simplifies designs that must run from a single Li-ion cell, two AA cells, or a regulated 3.3V/5V rail.
The PIC16F1619 uses a 14-bit instruction word modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. The 32 MHz internal oscillator (8 MHz x 4 PLL) is factory-trimmed to within +/-1% across the industrial temperature range, which is sufficient for UART baud-rate accuracy without an external crystal in most cases. The PPS module is a key architectural feature that allows most digital peripherals to be routed to nearly any I/O pin, simplifying PCB layout and BOM reuse across the family.
Typical applications include BLDC/PMSM small-motor control (with the 24-bit SMT for back-EMF sensing), LED lighting control, switched-mode power supply (SMPS) control loops, fan and pump controllers, AC line zero-cross detection for triac/SCR dimming, and general-purpose sensor-interface nodes. The wide operating voltage and low-power XLP modes also make it a strong fit for battery-powered IoT edge nodes.
When designing with this device, pay attention to the in-circuit serial programming (ICSP) pins (ICSPCLK/ICSPDAT) which must be accessible on the PCB for production programming and debug. Decouple VDD with a 100nF ceramic capacitor placed within 5 mm of the pin, and add a bulk capacitor (>= 1 uF) if the application drives heavy loads. The MCLR pin requires a 10 kohm pull-up to VDD; do not leave it floating, even in production.

典型应用
PIC16F1619-E/P 适用于 6 应用s: BLDC/PMSM Small Motor Control, AC Line Zero-Cross Dimming, Switched-Mode Power Supply (SMPS) Control, Fan and Pump Speed Controllers, LED Lighting Control Nodes, Battery-Powered IoT Sensor Nodes.
BLDC/PMSM Small Motor Control
The PIC16F1619-E/P is well suited for small BLDC and PMSM motor control because its 24-bit Signal Measurement Timer (SMT) provides sub-microsecond period and duty-cycle measurement needed for back-EMF zero-cross detection at low RPM. Placed as the main control MCU between a 3-phase gate driver and the motor windings, the 32 MHz core delivers the interrupt response time required for sensorless trapezoidal commutation while keeping firmware lean. Compared with a generic 8-bit MCU lacking the 24-bit SMT, this part eliminates the external timer IC typically required for back-EMF period measurement, reducing BOM cost and PCB area.
推荐
AC Line Zero-Cross Dimming
For AC line TRIAC or SCR dimming, the PIC16F1619-E/P's Zero-Cross Detect (ZCD) module directly senses the AC mains zero-cross event without external comparators, simplifying the analog front-end to a single resistor divider. The CCP module then generates the firing-angle delay with 1 us resolution at 32 MHz, supporting both leading-edge and trailing-edge dimmer topologies. The wide 1.8-5.5 V VDD range lets the same firmware power the MCU from the line-derived 3.3 V rail, eliminating auxiliary supply circuitry in dimmer designs.
推荐
Switched-Mode Power Supply (SMPS) Control
The PIC16F1619-E/P can implement closed-loop digital control of small buck/boost SMPS topologies using the 10-bit ADC2 with Computation for high-speed voltage and current sensing, and the CCP/PWM for switch duty-cycle control. At 32 MHz the firmware loop can run the control algorithm at 100 kHz+ with margin for input voltage feed-forward. The PIC16F1619's CCM (Current Controlled Modulator) and PWM peripherals directly support peak current-mode control, replacing a dedicated PWM controller IC in sub-100 W designs.
推荐
Fan and Pump Speed Controllers
For variable-speed fan or pump controllers, the PIC16F1619-E/P reads tachometer feedback via the SMT, computes the PI control loop, and drives the motor FETs via PWM. The industrial -40 C to +125 C temperature grade ensures operation in enclosed motor housings where ambient temperatures reach 85 C+. The 14 KB Flash holds both the speed-control state machine and a user-configurable UART command interface, replacing discrete analog control boards with a single 8-cent MCU solution.
推荐
LED Lighting Control Nodes
Smart LED drivers and constant-current controllers benefit from the PIC16F1619-E/P's PWM resolution and ZCD for AC-DC LED retrofit lamps. The 24-bit SMT enables smooth logarithmic dimming curves that match human eye perception, while the 10-bit ADC2 with Computation handles high-side current sensing without external op-amps. The 1.8-5.5 V VDD range lets the MCU run directly from a small linear regulator after the bridge rectifier, removing the need for a separate isolated supply.
推荐
Battery-Powered IoT Sensor Nodes
For battery-powered sensor edge nodes, the PIC16F1619-E/P's XLP (eXtreme Low Power) variants provide nanoWatt sleep currents below 50 nA in deep sleep, allowing multi-year coin-cell operation with periodic sensor reads. The 32 MHz core wakes from sleep in microseconds to service a sensor read, compute, and sleep again, while the PPS module routes UART/I2C/SPI to any pin for flexible sensor PCB layout. The 1.8-5.5 V range lets the same firmware run from 1S Li-ion (3.7 V) or 2x AA (3.0 V) battery packs without redesign.

关键差异点

- Industrial -40 C to +125 C temperature grade as standard （对比 PIC16F1619-I/P)

设计说明
Decouple VDD (pin 20) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a bulk capacitor of at least 1 uF for designs that drive heavy GPIO loads or switch FETs. The PIC16F1619-E/P operates from 1.8 V to 5.5 V; do not exceed 5.5 V or the brown-out detector may not protect the device on slow rising supplies.
The MCLR pin (pin 1) requires a 10 kohm pull-up resistor to VDD - never leave it floating even in production designs. If unused, MCLR may be tied directly to VDD, but this disables in-circuit serial programming (ICSP). The ICSPCLK/ICSPDAT pins must remain accessible for production programming and debug, even if unused in the application firmware.
Place the decoupling capacitor within 5 mm of VDD pin 20 and route VDD with a wide trace to handle the inrush current when peripherals wake from sleep. If using an external crystal on OSC1/OSC2 (pins 9, 10), keep the crystal traces short, symmetric, and surrounded by a grounded guard ring to reduce EMI pickup. Avoid routing high-speed switching signals (PWM, gate drive) under the crystal traces.
