8-bit MCUs tout 15-W USB power delivery
Microchip’s AVR DU 8-bit MCUs integrate a USB 2.0 full-speed interface that supports power delivery up to 15 W, enabling USB-C charging at up to 3 A at 5 V. According to the manufacturer, this capability, not commonly found in other USB microcontrollers in this class, allows embedded designers to implement USB functionality across a wide range of systems.
In addition to higher power delivery than previous devices, AVR DU microcontrollers also feature improved code protection. To defend against malicious attacks, the devices employ Microchip’s Program and Debug Interface Disable (PDID) function. When enabled, the PDID function locks out access to the programming/debugging interface and blocks unauthorized attempts to read, modify, or erase firmware.
To enable secure firmware updates, the MCUs provide read-while-write flash memory in combination with a secure bootloader. This allows designers to use the USB interface for in-field updates without disrupting product operation.
The AVR DU family of MCUs is suitable for a range of embedded applications, from fitness wearables and home appliances to agricultural and industrial applications. A virtual demonstration of the MCU’s USB bridge is available here.
