About XC23xxB microcontrollers

The XC2300B series, with the XC2336B (LQFP-64) and XC236xB (LQFP-100) derivatives, is the low-end extension of the XC2300 microcontroller family focussing on Safety applications. With a total memory size of up to 320kB Flash and up to 34kB RAM running at up to 80MHz, the microcontrollers of this series are well suited for low-end cost-sensitive safety applicationss like Airbag, low-end Braking or Belt Pretensioner applications.

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 reduced 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
