The RTK5RX65N0C00000BR is a comprehensive development kit manufactured by Renesas for the RX65N MCU. It comes with all of the components necessary for experimenting with the RX65N MCU, including an evaluation board with a Pmod socket, GPIO, and a prototyping area. The evaluation board consists of a 32-bit Arm Cortex-M3 CPU core, 8KB of RAM, 192KB of ROM, two serial interfaces, 2 16-bit timers, 8 10-bit A/D converters, 15 GPIO pins, and other peripheral features. The Pmod socket allows you to quickly and easily add accessories to the board, such as displays, sensors, communications modules, and more. The GPIO pins provide access to an array of external components, and the prototyping area allows experimentation with high frequencies, digital logic, analog circuits, and more.
