CPU_45A-V3应用开发板

XMC4000 Application Ki t For XMC4000 Family

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.

CPU_45A-V3应用开发板主要特性:

The CPU_45A-V3 board is equipped with the following features XMC4500 (ARM® Cortex?-M4-based) Microcontroller, 120 MHz CPU clock, 1 MByte on-chip Flash, 160 kByte RAM, LQFP-144,
