PIC18F26Q10-I/ML Обзор
What is an 8-bit PIC microcontroller? An 8-bit PIC microcontroller is a Harvard-architecture microcontroller based on an 8-bit data path with separate program and data buses, designed for deterministic real-time control. The PIC18 Q10 family sits within Microchip's broader PIC18 (8-bit) -> PIC microcontroller -> microcontroller -> embedded processor hierarchy, offering more peripherals, memory, and CIPs (Core Independent Peripherals) than baseline PIC10/12/16 parts. The "Q10" family name is a Microchip branding convention denoting the integrated analog and CIP feature set.
Key features of the PIC18F26Q10-I/ML include Core Independent Peripherals that offload timing-critical tasks from the CPU, eXtreme Low Power (XLP) technology for energy-sensitive designs, 5V operation for increased noise immunity in industrial environments, and a Functional Safety (FuSa) feature set targeting IEC 61508 / SIL-capable applications. The 28-QFN package provides a small 6x6 mm footprint suitable for space-constrained sensor nodes and motor-control boards.
Typical applications include IoT sensor nodes, real-time control loops, lighting ballast controllers, white-goods motor drivers, automotive body and sensor modules, and any cost-sensitive embedded design requiring deterministic CIP-based timing. The 5V tolerant I/O makes it well suited for industrial environments with long cable runs where ground bounce and EMI are concerns.
When designing with this device, ensure proper decoupling (100 nF + bulk capacitor near VDD), review the device's errata for any CIP-specific limitations, and confirm whether the I/ML (28-QFN) package matches your PCB layout - the same PIC18F26Q10 die is also offered in SOIC-28, SSOP-28, and QFN-28 variants for layout flexibility.

Home Appliance Motor Control
In washing-machine, dishwasher, and refrigerator motor-control boards, the PIC18F26Q10-I/ML drives BLDC and brushed-DC motors via its Complementary Waveform Generator (CWG), PWM peripherals, and configurable logic cells. The CWG can produce dead-band-controlled complementary outputs for half-bridge MOSFET drivers without CPU intervention, reducing CPU load by 60-80% versus software-only PWM. The 64 MHz CPU clock supports FOC loop update rates of 15-20 kHz at 8 kHz PWM. The 28-QFN package with exposed pad handles up to 1.5 W dissipation comfortably for these applications. The 5V I/O tolerance interfaces directly to legacy gate-driver ICs without level shifters.

Заметки по проектированию
Place a 100 nF ceramic decoupling capacitor on each VDD/AVDD pin pair within 5 mm of the package, plus a single 10 uF bulk capacitor near the supply pin. The PIC18F26Q10-I/ML has separate analog (AVDD/AVSS) and digital (VDD/VSS) supply pairs to reduce ADC noise coupling. For best ADC accuracy, route AVDD through a ferrite bead from VDD rather than connecting them directly. The exposed thermal pad (EP) of the 28-QFN package MUST be soldered to a copper pour on the PCB and connected to AVSS for thermal and electrical performance.
The 28-QFN package has a 6x6 mm footprint with an exposed thermal pad that requires thermal vias (typically 9-16 vias in a 3x3 or 4x4 array, 0.3 mm drill) to a bottom-layer copper pour. Place the MCLR/VPP/RE3 pin pull-up resistor (typically 10 kohm) close to the pin to ensure clean reset transitions. The ICSP programming pins (PGC/PGD = RB6/RB7) should have 4.7 kohm series resistors in production designs to allow in-circuit programming without disrupting the application circuit.
Two common pitfalls with the PIC18F26Q10-I/ML: (1) The /ML (QFN) and /SO (SOIC) packages have identical silicon but different footprints - do not assume pin compatibility at the PCB level. (2) The MCLR pin (RE3) is a dedicated reset input on QFN-28; it CANNOT be used as a general-purpose I/O on QFN-28 (unlike larger QFN packages where RE3 is a GPIO). Consult the device errata for CIP-specific limitations, particularly for the CWG and SCAN peripherals, before committing to firmware architectures. Use only Microchip-supported compilers (XC8) for FuSa-certified designs.
Estimated: At 64 MHz CPU clock and full peripheral activity, the PIC18F26Q10-I/ML dissipates roughly 30-50 mW typical, well within the 28-QFN package's thermal capability. The exposed thermal pad has a theta-JA of approximately 30-35 C/W on a standard 4-layer JEDEC test board. At +85 C ambient, this gives 95-100 C junction temperature, below the +150 C maximum. For designs at +125 C ambient (using the -E/ML variant), ensure the PCB copper pour is at least 100 mm^2 on top layer connected to the EP to keep junction temperature under +150 C.
