PIC16F1773T-I/SS Présentation
A PIC microcontroller is a compact, low-cost, Harvard-architecture RISC processor with on-chip Flash, RAM and peripherals designed to be programmed once and embedded inside an appliance, sensor, lighting controller or motor drive. It sits within a hierarchy of MCU -> embedded controller -> microcontroller -> semiconductor. The PIC16F1773 belongs to the PIC16F177x sub-family, which is positioned for intelligent analog and digital peripheral integration in lighting, power conversion and battery-charging applications.
Key features of the PIC16F1773T-I/SS include 25 digital I/O pins, a 10-bit ADC, multiple PWM/capture/compare/PWM (CCP) modules, configurable logic cells (CLC), operational amplifiers, comparators and a 32 MHz internal oscillator. These integrated peripherals eliminate many external components, shrinking BOM cost in LED drivers, switch-mode power supplies and motor-control loops. The XLP variant keeps active current low for battery-powered end nodes.
Typical applications include commercial and industrial LED lighting, digital switch-mode power supplies, battery chargers, DC-DC converters, BLDC/PMSM motor control firmware, and general-purpose embedded control with mixed-signal demands. The wide 2.3 V to 5.5 V operating range lets the same part serve a 3.3 V logic rail and a 5 V sensor rail from a single MCU.
When designing with the PIC16F1773T-I/SS, plan the ICSP™ programming/debug pinout early because the same pins (PGED/PGEC, MCLR) used for in-circuit serial programming also constrain the PCB layout. For analog-heavy designs, leverage the integrated op-amp and comparator to remove external analog ICs, and use the configurable logic cells (CLC) for glue logic without burning gates.

Applications typiques
PIC16F1773T-I/SS convient pour 6 applications: Commercial LED Lighting Drivers, Digital Switch-Mode Power Supplies, Battery Charging Controllers, BLDC / PMSM Motor Control, Industrial Sensor Hubs, Portable / Battery-Operated IoT Nodes.
Commercial LED Lighting Drivers
The PIC16F1773T-I/SS is a strong fit for commercial LED lighting drivers because the integrated op-amps, comparators and configurable logic cells (CLC) enable constant-current feedback loops without external analog ICs. The 32 MHz CPU and ECCP/CCP modules support high-resolution PWM dimming above 1 kHz, eliminating visible flicker while the XLP nanoWatt technology keeps standby current low for energy-star compliance.
Recommandé
Digital Switch-Mode Power Supplies
In a digital SMPS the PIC16F1773T-I/SS can host the compensation loop, soft-start, and housekeeping telemetry. The 32 MHz MIPS throughput runs 50-100 kHz control loops while the 10-bit ADC samples current and voltage feedback. The 2.3 V to 5.5 V supply range accepts the auxiliary rail directly and the 7 KB Flash fits typical state-machine plus lookup-table compensation.
Recommandé
Battery Charging Controllers
The PIC16F1773T-I/SS drives CC/CV battery-charging algorithms for Li-Ion, lead-acid and NiMH packs. Its integrated comparators sense battery voltage and current, while the ADC samples temperature from an external thermistor for thermal protection. XLP nanoWart technology reduces quiescent draw when the charger is connected to a battery but no load is present, extending shelf life.
Recommandé
BLDC / PMSM Motor Control
Sensorless BLDC and PMSM motor control relies on back-EMF zero-cross detection and PWM commutation. The PIC16F1773T-I/SS exposes comparators and op-amps needed for back-EMF sensing, plus multiple PWM channels that drive a 3-phase FET bridge. The 25 I/O pins handle Hall inputs, fault output, brake coil and tachometer simultaneously without external logic.
Recommandé
Industrial Sensor Hubs
Industrial sensor hubs aggregate temperature, pressure and flow signals into Modbus or CAN-fd output. The PIC16F1773T-I/SS supports the 10-bit ADC scanning for analog sensors, EUSART for RS-485/Modbus RTU, and industrial -40 °C to +85 °C temperature range for cabinet mounting. The 128-byte EEPROM stores calibration and unit identity persistently across power cycles.
Recommandé
Portable / Battery-Operated IoT Nodes
The XLP nanoWart technology inside the PIC16F1773T-I/SS makes it a fit for coin-cell or 2xAA powered IoT nodes that sleep most of their duty cycle. Sleep current in the nA range combined with fast wake from the internal 32 MHz oscillator lets a sensor node spend >99% of its time in standby and still wake fast enough for periodic uplink transmissions.

- Integrated op-amps, comparators and CLC cells reduce BOM count (vs PIC16F1716-I/SS)
Notes de conception
Route the ICSP pins (PGC/PGD on RB6/RB7 plus MCLR) to a 6-pin or 8-pin header following Microchip's ICSP layout guideline so the PICkit 4 or MPLAB Snap programmer can attach without rework. Add a 10 kΩ pull-up on MCLR to VDD unless the device is always-on. Keep the ICSP traces short and isolated from switching nodes.
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, plus a bulk 10 µF tantalum or ceramic on the same rail. Place a 10 µF bulk at the regulator output when the device drives FET bridges. The internal LDO is sensitive to fast supply transients, so avoid sharing its decoupling with high-di/dt nodes.
Do not float unused I/O pins. Configure them as outputs or enable the internal weak pull-up; floating inputs may source/sink mA-range current and inject noise through the analog mux. When migrating firmware from PIC16F1776 to PIC16F1773, audit interrupt vector names and peripheral library versions because enhanced mid-range peripheral libraries differ between the two parts.
When using the internal op-amp for current sensing in SMPS or motor control, place the sense resistor and feedback traces on a quiet ground island separate from the digital switching returns. Use guard rings around the analog input pins to avoid digital crosstalk. The 10-bit ADC is adequate for most loop bandwidths below 50 kHz.
At 32 MHz CPU and full I/O switching, the 28-SSOP package dissipates <100 mW - well within the SSOP's 150 °C/W θJA. Estimated: at 25 °C ambient and 100 mA active, junction rise is about 4 °C. For elevated-temperature (>70 °C) cabinets, derate at most a few mW/MHz and ensure the PCB copper area exceeds 100 mm² for any safety margin.
