SAM3U Series: 96 MHz Cortex-M3 Flash MCU with High-Speed USB

Atmel´s SAM3U series is the world´s first 32-bit ARM Cortex™-M3 Flash microcontroller with high-speed 480 Mbps USB + Phy.

High-SpeedUSB

The SAM3U is the first Cortex-M3 microcontroller with high-speed USB and an integrated transceiver for fast up/downloading of data, robust EMI tolerance, and plug-and-play high-speed serial interconnectivity.

High Performance

Features a 96 MHz maximum operating frequency and a high data-bandwidth architecture based on a 5-layer bus matrix with 22 DMA channels and distributed memory

Dual-Bank Flash

Provides safe in-application programming(IAP) including the boot program

1.62 to 3.6V Operation

True1.8V±10% operation extends device operation when running from two AA alkaline batteries

Memory Protection Unit

Improves code protection and secures multi-application/task execution

High-EndAnalog

Features a differential input and programmable gain amplifier (PGA) on a 12-bit 1 Msps ADC

SAM3U-EK & SupportEcosystem

For rapid evaluation and code development. Industry-leading third parties provide a full range of development tools, RTOS, middleware and support services to reduce time-to-market to a minimum.
