Introduction
This document describes the features and hardware details of the CPU Board XMC4500 General Purpose
(CPU_45A-V3)
designed to work with Infineon’s XMC4500 Microcontroller. This board is part of Infineon’s
XMC4000 Application Kits.
1
Overview
The CPU board CPU_45A-V3 houses the XMC4500 Microcontroller and three satellite connectors (HMI, COM,
ACT) for application expansion. The board along with satellite cards (e.g. HMI_OLED-V1, COM_ETH-V1,
AUT_ISO-V1, MOT_GPDLV-V boards) demonstrates the capabilities of XMC4500. The main use case for this
board is to demonstrate the generic features of XMC4500 device including tool chain. The focus is safe
operation under evaluation conditions. The board is neither cost nor size optimized and does not serve as a
reference design.
