Double Precision Floating point unit (FPU) for high-precision computing and accelerated data processing.

The SAM E70 series offers a rich set of advanced connectivity peripherals, including 10/100Mbps Ethernet MAC supporting IEEE 1588, dual CAN-FD 1.0, High Speed USB Host and Device with on-chip high-speed phy, Camera Interface, one SD/MMC interface, one SSC supporting TDM and I2S, 8 UARTs, 5 SPI and 3 I2C™. A QSPI, static memory and SDRAM interface offer further memory extension options. SAM E70 series of Flash microcontrollers (MCUs) operates at a maximum speed of 300MHz and features up to 2048kB of Flash, 16KB each instruction plus data cache and up to 384KB of SRAM. The two boards share the same development environment. It is similar to the SAMA5D3 Xplained Evaluation Board (SAMA5D3-XPLD), but with the PHYs removed and replaced by the RMII and RGMII connectors. This board is built around a Cortex®-A5-based processor on-board SDRAM and Flash memory, two Ethernet MACs (one gigabit and one 100 Mbit), three USB ports, an SD card slot, and a Serial UART interface. Source code is available for download from the website for this board, and users may modify and append to it for their needs. Users can also access registers and statistics counters in the PHY or switch, set up VLAN and other configurations in a switch, and perform traffic testing to/from the MCU. When mated to a switch evaluation board, the included software can run protocols, such as RSTP, DHCP, and PTP (1588). The SAMA5D3 EDS board comes with pre-installed Linux and Ethernet drivers. The EDS board is not intended for stand-alone use and has no Ethernet capabilities when no daughter board is connected. These daughter boards are available separately.

Compatible switch and PHY evaluation boards connect to the EDS board via either an RGMII connector or an RMII connector. The Microchip SAMA5D3 Ethernet Development System board (EDS) board is an MPU-based platform for evaluating Ethernet switch and PHY products.
