With 35 I/O lines and an 11-channel 12-bit ADC, it can handle a mix of digital sensors, relay drivers, and analog feedback in a single package. ## Industrial temperature and 44-QFN — board-level fit The 44-QFN package (8x8 mm) with an exposed pad needs a good thermal via stitch under the pad if the MCU drives more than a few hundred milliamps through its I/O pins — the die's junction-to-ambient thermal resistance benefits from a copper pour on the bottom layer. The part is ROHS3 compliant.","metaTitle":"PIC18F46K80-I/ML Microchip 8-bit MCU, 64KB Flash, 64MHz","metaDescription":"Microchip PIC18F46K80-I/ML 8-bit MCU with 64KB Flash, 64MHz core, 3.6KB RAM, ECANbus, I2C, SPI, UART, 1.8V-5.5V, -40°C to 85°C, RoHS3.
