PIC16F1773-I/SO Übersicht
An 8-bit PIC microcontroller is a Harvard-architecture RISC processor designed for low-power deterministic control with a small instruction set of approximately 35 to 75 instructions optimized for embedded real-time tasks. Within the broader hierarchy, this places the PIC16F1773-I/SO as: microcontroller -> MCU -> embedded processor -> semiconductor IC. The XLP™ (eXtreme Low Power) family targets battery-backed and energy-harvesting applications where nanoWatt sleep currents extend operating life.
Key features include a 10-bit ADC with up to 17 channels, a 10-bit DAC, a 5-bit DAC, multiple operational amplifiers, high-speed comparators, zero-cross detect (ZCD), programmable ramp generator (PRG), 100 mA I/O drive capability, peripheral pin select (PPS), 10/16-bit PWMs with complementary outputs, plus SPI, I²C, and EUSART communication peripherals. These integrated analog peripherals target LED lighting, power conversion, and motor-control applications.
Technically, the PIC16F1773-I/SO uses a modified Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and operand access. The instruction pipeline and 14-bit instruction word balance code density with deterministic interrupt latency, while the integrated CIP (Core Independent Peripherals) allow closed-loop tasks such as power-factor correction and SMPS control without CPU intervention.
Typical applications include LED drivers and architectural lighting, AC/DC and DC/DC SMPS control, battery charging and battery management, brushless DC (BLDC) and stepper motor control, and industrial low-power sensing nodes. The combination of high-resolution PWM, on-chip op amps, and configurable logic makes it a frequent choice for digital power conversion.
When designing with this part, validate that your firmware routine on peripheral interrupts does not starve the ADC sequencer; consider the PPS routing table when remapping peripherals to non-default pins, and always review the Electrical Characteristics chapter for the latest VOH/IOH specifications of the high-current 100 mA I/O pins.

LED Lighting Drivers
The PIC16F1773-I/SO is purpose-built for high-end LED lighting with its integrated 10-bit and 5-bit DACs, on-chip operational amplifiers, and 16-bit PWM with complementary outputs. The 10-bit DAC enables precise color-mixing across RGB or RGBA strings, while the op amps close the current loop around external MOSFETs to keep LED forward current constant across temperature. The 100 mA high-current I/O bank can directly drive mid-power LED chains without external drivers, and the zero-cross detect (ZCD) simplifies TRIAC dimmer compatibility for retrofit bulb designs. At 32 MHz, the MCU handles 16-bit dimming resolution at flicker-free PWM frequencies above 20 kHz. The 28-SOIC industrial temperature rating (-40 °C to +85 °C) covers outdoor luminaire and architectural lighting environments. Recommended MPNs reflect Microchip's lighting reference designs and the PIC16F1769-I/SO as a cost-down option when 5-bit DAC is not required.

AC/DC and DC/DC SMPS Control
The PIC16F1773-I/SO's programmable ramp generator (PRG) and high-speed comparators enable digital peak-current-mode control of AC/DC and DC/DC switch-mode power supplies. The PRG synthesizes slope compensation for converters operating above 50% duty cycle, eliminating the analog RC network traditionally used. 10/16-bit PWMs with complementary outputs drive synchronous-rectifier half-bridges at up to 32 MHz peripheral clock, while 100 mA I/Os can directly gate low-side MOSFETs. The integrated 10-bit ADC samples current and voltage at the PWM switching frequency, and the on-chip op amps condition feedback signals without external amplifiers. The XLP nanoWatt sleep modes let the MCU survive auxiliary-supply stand-by conditions in compliance with energy-star and 80 Plus efficiency targets. Nova Microchip's CIP-driven SMPS architecture lets a single PIC16F1773 replace the analog controller plus supervisor IC in many sub-100 W designs. Recommended companion MPNs include the PIC16F1773-E/SO for higher-temperature industrial PSU environments.

Battery Charging and Battery Management
The PIC16F1773-I/SO suits multi-chemistry battery chargers with its 10-bit ADC monitoring voltage and current, 10-bit DAC setting charge current/voltage references, and on-chip comparators for safety termination. The ZCD block synchronizes charger operation to AC line frequency for power-factor-corrected chargers, while the 16-bit PWM drives the primary-side MOSFET at a frequency that can be tuned above AM band. The XLP nanoWatt deep-sleep modes keep the MCU alive on a coin-cell during storage or transport without draining the battery, and the 2.3-5.5 V VDD range accepts single-cell Li-ion, two-cell alkaline, or 5 V USB input directly. The 7 KB FLASH holds a CC-CV-Li-ion or lead-acid charge profile with logging and LED status, while 256 B EEPROM stores calibration and cycle-count data. The 28-SOIC package fits inside standard charger bricks and portable power banks.

Brushless DC (BLDC) and Stepper Motor Control
The PIC16F1773-I/SO drives BLDC and stepper motors with its 16-bit PWM generating complementary 3-phase gate signals and its high-speed comparators implementing hardware over-current protection. The on-chip op amps condition back-EMF or Hall-sensor signals, while the 10-bit ADC digitizes phase currents for sensorless FOC entry modes. The 100 mA I/O drives directly interface 5 V gate drivers such as the Microchip MCP14700 family, eliminating level shifters in 24 V motor systems. The PRG block implements torque-per-amp profiling and soft-start ramps, and the EUSART links the controller to an external HMI or PLC master. At 32 MHz, the firmware completes one FOC iteration in microseconds, leaving headroom for housekeeping tasks. The industrial temperature range supports factory-floor and outdoor motor applications. Recommended MPNs include the PIC16F1713-I/SO when an additional op amp is required for current sensing.
Empfohlen
Industrial Low-Power Sensing Nodes
The PIC16F1773-I/SO anchors industrial wireless sensor nodes with its XLP nanoWatt sleep currents below 100 nA, allowing multi-year operation from a single CR2032 cell. The 10-bit ADC scans up to 17 channels for temperature, humidity, pressure, or 4-20 mA loop sensors, while the 5-bit DAC and on-chip op amp deliver excitation signals to resistive bridges. SPI/I²C/EUSART connect to radios such as the Microchip MRF24XA or external LoRa modules, and PPS lets the firmware remap peripherals to any pin for optimal PCB layout. The 256-byte EEPROM stores calibration data and node IDs, while 7 KB FLASH holds protocol stacks for Modbus, IO-Link, or proprietary wireless. Industrial -40 to +85 °C operation covers factory-floor and outdoor cabinet environments. Recommended MPNs include the PIC16F1768-I/SO for compact form factors where the full 7 KB FLASH is not needed.

Smart Home and IoT Edge Devices
The PIC16F1773-I/SO drives smart-home hubs and edge devices with its combination of PWM (for dimming), 10-bit ADC (for sensor reading), and EUSART/SPI/I²C (for radio and cloud links). The XLP technology keeps the MCU quiescent at nanoamp-level draw between events, critical for battery-powered door sensors, window sensors, and HVAC thermostats. The peripheral pin select (PPS) reassigns UART and PWM to any GPIO, simplifying PCB routing when adding BLE or LoRa daughter boards. The on-chip op amps and 5-bit DAC generate bias currents for thermistors or photodiodes, reducing BOM cost in compact IoT products. 7 KB FLASH accommodates Over-the-Air (OTA) bootloader stubs for firmware updates, while 256 B EEPROM stores network credentials and pairing keys. Recommended MPNs include the PIC16F1769-I/SO as a cost-down option for high-volume SKUs.

Automotive Body and Lighting Modules
The PIC16F1773-I/SO serves interior lighting, ambient lighting, and body-control modules with its 100 mA high-current I/Os capable of directly driving LED strings without external drivers. The 16-bit PWM with complementary outputs drives RGB tail-light and interior-strip LEDs at flicker-free frequencies, while the 10-bit ADC monitors battery voltage for low-voltage warning logic. The on-chip op amps interface with thermistors for ambient-light and temperature compensation, and the SPI/I²C/EUSART peripherals connect to LIN transceivers for body-network communication. The industrial -40 to +85 °C rating covers cabin and under-hood-near-body environments, while extended-temperature variants handle harsher locations. PIC16F1773-I/SO is widely used in aftermarket LED controllers and motorcycle/Bus lighting retrofits. Recommended MPNs include the PIC16F1773-E/SO for under-hood and engine-bay mounted lighting.

Designhinweise
PIC16F1773-I/SO operates from 2.3 V to 5.5 V; place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin and a bulk 10 µF tantalum or ceramic capacitor on the same node. For dual-VDD 28-SOIC pins, populate both VDD pins to reduce ground bounce. The MCU's nanoWatt XLP sleep currents (below 100 nA in deep sleep) only hold if all unused I/Os are configured as outputs and pulled to defined logic levels; floating inputs can leak several microamps.
Route the ICSP pins (RB6/PGC and RB7/PGD) as a 2-pin header or test pad cluster to allow in-circuit programming and debugging. Use Peripheral Pin Select (PPS) to remap UART, PWM, and SPI functions to free GPIO, keeping the PCB layout flexible. Keep analog traces (ANx, op-amp inputs, comparator inputs) short and away from PWM and switching traces; guard the analog ground with a star-ground topology back to the VSS pin to preserve 10-bit ADC accuracy.
The 100 mA high-current I/O pins can sink/source strong loads, but the absolute maximum per pin and per-port limits must be observed; never parallel more than the recommended number of high-current pins simultaneously or the package thermal limit is exceeded. The MCLR pin (RE3) is the only reset source on this part - leaving it floating will cause intermittent resets from noise; tie it to VDD via a 10 kΩ resistor with a 100 nF decoupling cap for noise immunity. The 16-bit PWM with complementary outputs requires dead-band setup, otherwise fields can short the half-bridge. Estimated: under worst-case conditions the 28-SOIC package dissipates up to 800 mW - respect the theta-JA of approximately 80 °C/W.
The 28-SOIC package has a thermal resistance of approximately 80 °C/W. At full 32 MHz operation with all peripherals active, the device draws roughly 6-8 mA from VDD (typical); at 5 V supply this is approximately 30-40 mW of dissipation, giving a junction temperature rise of about 3 °C above ambient. For closed-enclosure designs (luminaire housing, sealed sensor), derate by reducing FOSC or using sleep modes to maintain junction temperature below 125 °C.
