About XC23xxE microcontrollers

The XC23xxE series is the high-performance extension of the XC2300 microcontroller family focussing on Safety applications.

The integrated instruction cache (iCache) offers a strong performance boost of up to 30%. In addition the frequancy increase of up to 128MHz brings further

performance improvements.

The new devices of this series, equipped with up to 1MB embedded Flash and optional FlexRay are geared towards automotive Safety applications, like

high-end Airbag, Electric Power-Steering (EPS) or Braking,  requiring a higher range of performance or the potential for future performance improvements.

Customer benefits
  • Fast time to market due to Infineon's proven in use safety concept
  • Comprehensive safety documentation intelligent error management avoids false alarm and therefore, reduces FIT and DPPM rate 
  • Scalable platform guarantees optimized cost-performance ratio 
  • Supports ASIL requirements
XC2300 and CIC61508

The implementation of ISO26262 and IEC61508 std. compliant safety critical systems requires an independent robust safety watchdog for main microcontroller supervision.

Thus, microcontroller-based safety systems, must be made of three components: Main microcontroller, an independent watchdog with robust monitoring channels, and a supporting safety software.

With its safety computing platform, Infineon covers all of these three needed components: The XC2300 MCU family, the CIC61508, an independent 

robust watchdog plus, the SafeTcore safety library.

All three components were specified and developed for efficient implementation and fast  time to market.

Typical target applications of Infineon’s safety computing platform are IEC61508 and SIL3 

and ISO26262 and ASIL-C-ASIL-D applications.

CIC61508: 

  • Intelligent error management
  • Robust monitoring channel
  • Up to three safety enable and disable paths
  • Task monitoring
  • Wide temperature range (-40°C to 140°C)
  • TSSOP-38 package

SafeTcore library:

  • Processor monitoring and self-tests
  • Independent safety monitor software with tasking V5r2p3
  • supports ISO26262 and IEC61508
  • Small memory footprint typ. 92 KB ROM
