Microchip’s AVR DU 8-bit MCUs combine a USB 2.0 full-speed interface that helps energy supply as much as 15 W, enabling USB-C charging at as much as 3 A at 5 V. In line with the producer, this functionality, not generally present in different USB microcontrollers on this class, permits embedded designers to implement USB performance throughout a variety of methods.
Along with greater energy supply than earlier gadgets, AVR DU microcontrollers additionally characteristic improved code safety. To defend in opposition to malicious assaults, the gadgets make use of Microchip’s Program and Debug Interface Disable (PDID) operate. When enabled, the PDID operate locks out entry to the programming/debugging interface and blocks unauthorized makes an attempt to learn, modify, or erase firmware.
To allow safe firmware updates, the MCUs present read-while-write flash reminiscence together with a safe bootloader. This enables designers to make use of the USB interface for in-field updates with out disrupting product operation.
