For New Designs, we highly recommend to consider Revision B for Prototypes and Production.

ARM® Cortex®-M4 processor-based microcontroller (MCU), the SAM4E16E features a floating point unit and a high data bandwidth architecture and is targeted at industrial automation and building control applications.

The device embeds 1MB Flash and features multiple networking/connectivity peripherals, including two 2.0A/B compatible CAN interfaces and an IEEE Std 1588-compatible 10/100Mbps Ethernet MAC. Additional communication interfaces include a FS USB device, a HS SDCard/SDIO/MMC interface, USARTs, SPIs and multiple TWIs.

Analog features include dual 1Msps, 16-bit ADCs of up to 24 channels with analog front end offering offset and gain error correction, and a 2-channel, 1Msps, 12-bit DAC.

The SAM4E16E is available in 144-pin BGA and QFP package options.
