    ATtiny1627 microcontroller. The voltage limits configured in the on-board debugger on ATtiny1627 Curiosity Nano are 1.8-5.1V. Info:  The target voltage is set to 3.3V when the board is manufactured. It can be changed through MPLAB X IDE project properties and in the Atmel Studio device programming dialog.

  • Page 16: External Supply

    VBUS Output Pin ATtiny1627 Curiosity Nano has a VBUS output pin that can be used to power external components that need a 5V supply. The VBUS output pin has a PTC fuse to protect the USB against short circuits. A side effect of the PTC fuse is a voltage drop on the VBUS output with higher current loads.

  • Page 17: Power Supply Exceptions

    This is most lightly caused by a high-current drain on VBUS, and the protection fuse (PTC) will reduce the current or cut off completely. Reduce the current consumption on the VBUS pin to fix this issue. User Guide DS40002199A-page 17 © 2020 Microchip Technology Inc.
