This month, Infineon begins sampling its XMC4000 32bit micrcocontrollers which use ARM's Cortex-M4, combined with application-optimised peripherals. They can be used in electric drives, solar inverters and automating manufacturing and buildings. The XMC4100, XMC4200, XMC4400, XMC4500 and XMC4700 are scalable and are differentiated by the core frequency, memory capacity and peripheral functions and number of I/Os. The devices have DSP functionality, a floating point unit, a flash memory with only 22ns read time and error correction code and SRAM. Peripherals include timer modules, up to four parallel 12bit ADCs with a sampling rate of 70ns and a conversion time of 500ns, up to two 12bit DACs, up to four high-resolution PWM channels (150ps), integrated delta-sigma demodulator modules and touch button modules. Communication is provided by an IEEE 1588-compatible-Ethernet MAC, USB 2.0, CAN and SD/MMC interfaces and up to six serial communication channels which can be configured as UART, SPI, Quad SPI, IIC, IIS or LIN using software. There is also a fast external bus interface that supports synchronous standards such as SDRAM or burst flash, and asynchronous standards such as SRAM, NAND flash and NOR flash. The accompanying IDE, DAVE 3, supports automatic code generation based on predefined software components. These so-called DAVE Apps are configured via the GUI.
