Product Overview
The ATMEDA32U4-AU is factory configured with a USB boot loader located in the on chip flash boot section of the controller. This USB boot loader allows to perform in system programming from a USB host controller without removing the part from the system or without a pre-programmed application, and without any external programming interface.
- Auto baud (8/16 MHz crystal)
- Read/write flash and EEPROM on chip memories
- Read device ID
- Full chip erase
- Start application command
- Software entry points for on chip flash drivers
Applications
Automation & Process Control, Consumer Electronics, Embedded Design & Development, Sensing & Instrumentation
