Infineon expands XMC4000 mcu range

According to Infineon, the XMC4400, XMC4200 and XMC4100 are the first Cortex based microcontrollers to offer a high resolution PWM unit featuring a resolution of 150ps. It believes the parts are suitable for use in digital power conversion in inverters as well as in switching and uninterruptible power supplies. Dr. Stephan Zizala, Infineon's senior director, industrial and multimarket microcontrollers, said: "The new series combine all the strengths of the XMC4000 family with a high-resolution PWM unit. The result is a control quality comparable to the precision of analogue solutions." There are now four members of the XMC4000 family, which differ mainly in core frequency, memory capacity, peripheral functions and I/O. The XMC4400 series, available in a choice of LQFP100 or LQFP64 packages, runs at 120MHz and comes with up to 512k of flash. The XMC4200 and XMC4100 series – both available in lqfp64 or vqfn48 packages – runs at 80MHz. The XMC4200 has up to 256kbyte of flash and the XMC4100 has up to 128kbyte. Peripherals include high speed 12bit a/d and d/a converters, as well as an integrated delta-sigma demodulator in the XMC4400 family. Communications features include an Ethernet MAC (XMC4400), USB 2.0 and CAN interfaces as well as software configurable serial communication channels. Samples of the XMC4400, XMC4200 and XMC4100 are available, with volume production scheduled to start in the middle of 2013.
