Infineon expands XMC4000 microcontroller family with high-resolution PWM unit for efficient digital power conversion

November 27, 2012 // By Paul Buckley
Infineon Technologies AG has unveiled three new performance classes in its XMC4000 microcontroller family, which was specially developed for industrial applications and uses ARM Cortex M4 processors.

The new XMC4400, XMC4200 and XMC4100 are the world’s first Cortex-based microcontrollers to offer a high-resolution PWM unit. With a PWM resolution of just 150 ps, they are especially suitable for digital power conversion in inverters as well as switching and uninterruptible power supplies (UPS). Other applications are to be found in IO units in automation, user interfaces (HMI) and logging and control systems.

The new XMC4400, XMC4200 and XMC4100 series microcontrollers are part of the Infineon roadmap to serve a broad range of industrial applications with the XMC4000 family. Like the XMC4500 MCUs, the XMC4400, XMC4200 and XMC4100 series offer powerful application-optimized peripherals, fast and robust embedded Flash technology, an extended temperature range of -40°C to 125°C, high quality standards and tools for automatic code generation in the DAVE 3 development environment.

The XMC4000 family now comprises four series: XMC4500, XMC4400, XMC4200 and XMC4100. They differ mainly in core frequency, memory capacity, peripheral functions and number of IOs. The XMC4400, XMC4200 and XMC4100 series have a powerful CPU subsystem with 120 MHz or 80 MHz, DSP functionality, a Floating Point Unit, fast Flash memory (512 KByte, 256 KByte or 128 KByte) with a read time of just 22 ns and error correction code as well as SRAMs up to 80 KByte. The extensive range of peripherals includes high-speed 12-bit AD and DA converters as well as integrated delta-sigma demodulator modules (XMC4400). Powerful communication is provided by Ethernet MAC (XMC4400), USB 2.0 and CAN interfaces as well as serial communication channels which can be software-configured individually as UART, SPI, Quad-SPI, I 2S or I 2C. They also provide a touch interface and an LED matrix display.

DAVE 3 and third party tools for comprehensive and efficient development support for XMC4400, XMC4200 and XMC4100

The XMC4400, XMC4200 and XMC4100 also are supported with the integrated development platform DAVE 3, which makes convenient, fast and application-orientated software development possible. The Eclipse-based environment
