The Microchip ATUC128L3U-AUT is a 32-bit single-core microcontroller from the UC3 L series, clocked at 50 MHz.
An 8-channel 12-bit ADC handles analog sensor inputs without an external converter. The USB interface supports host or device roles, covering a wide range of embedded connectivity needs.
The part supports standard AVR32 debug and programming interfaces via the JTAG or aWire single-wire protocol, accessible through the 64-TQFP package pins. Development tools such as the Atmel-ICE or AVR ONE! are compatible.
