+Overview
+********
+
+The EV63J76A (SAMA7D65 Curiosity Kit) is a development kit for evaluating and
+prototyping with Microchip SAMA7D65 microprocessor (MPU). The SAMA7D65 MPU is a
+high-performance ARM Cortex-A7 CPU-based embedded MPU running up to 1GHz.
+
+The board allows evaluation of powerful peripherals for connectivity, audio and
+user interface applications, including MIPI-DSI and LVDS w/ 2D graphics, dual
+Gigabit Ethernet w/ TSN and CAN-FD.  The MPUs offer advanced security functions,
+like tamper detection, secure boot, secure key stoarge, TRNG, PUF as well as
+higher-performance crypto accelerators for AES and SHA.
+
+The SAMA7D65 series is supported by Microchip MPLAB-X development tools, Harmony
+V3, Linux distributions and Microchip Graphic Suite (MGS) for Linux. The
+SAMA7D65 is well-suited for industrial and automotive applications with
+graphical displays support up to WXGA/720p.
