Faster development of Functional Safety attributes for industrial applications

November 26, 2015 // By Graham Prophet
Advancing the development of Functional Safety industrial applications, Infineon's Safety Package for the XMC4000 family of 32-bit microcontrollers helps to develop TÜV-certified automation systems that conform with Safety Integrity Levels SIL2 and SIL3.

With the XMC4000 Safety Package Infineon helps to cut development time for the functional safety software test libraries down to an estimated one year. The XMC4000 Safety Package was developed specifically for industrial high-end applications such as factory automation, industrial motor control and robotics.

The XMC4000 Safety Package includes XMC4000 microcontroller hardware, detailed documentation and a TÜV-certified software test library, which was developed together with functional safety solution provider YOGITECH. It includes consultancy and implementation support by embedded engineering tool supplier Hitex that offers extensive experience in Functional Safety applications. The detailed documentation comprises a failure mode report, FMEDA (Failure Mode Effects and Diagnostic Analysis) based on liable FIT (failure in time) rates for the XMC4000 microcontrollers, and the Safety Application Note helping to develop SIL2 and SIL3 systems.

The detailed documentation from Infineon including the failure mode report, FMEDA and Safety Application Note will be available in January 2016. The non-TÜV-certified version of the XMC4000 Fault Robust Software Test Library (fRSTL) from YOGITECH will be available in December 2015. Under licence from YOGITECH or Hitex, the TÜV-certified version will be available in Q1 2016.

The XMC4000 family addresses industrial market needs; all XMC4000 devices are qualified for operation at 125°C ambient temperature. They are based on an ARM Cortex-M4 with a built-in DSP instruction set, Single Precision Floating Point Unit, Direct Memory Access (DMA) feature and Memory Protection Unit (MPU). All members of the XMC4000 family come with a set of common, fast and precise analogue/mixed signal, Timer/PWM and communication peripherals. The XMC4000 family today has six series: XMC4100, XMC4200, XMC4400, XMC4500, XMC4700 and XMC4800, with more than 75 devices in VQFN, LQFP and LFBGA packages scaling from 48 to 196 pins. The XMC4800 devices are the first highly integrated ARM Cortex-M4 based microcontrollers with integrated EtherCAT, bringing real-time Ethernet communication.
