FAQ

What is the maximum operating frequency and core architecture of the SPC560P34L1CEFAR?

The SPC560P34L1CEFAR operates at up to 64 MHz using the e200z0h 32-bit CPU core compliant with Power Architecture® embedded category. It supports Variable Length Encoding (VLE) to reduce code size by ~30% versus standard Power ISA, improving flash utilization in safety-critical firmware.

Does the SPC560P34L1CEFAR support functional safety certification per ISO 26262?

Yes - the device includes hardware safety mechanisms required for ASIL-B compliance: ECC on flash and SRAM, Fault Collection Unit (FCU), programmable watchdog timer, NMI, and Nexus Class 1 debug interface for runtime verification. ST provides safety manuals and FMEDA reports for integration into certified systems.

How many CAN interfaces does the SPC560P34L1CEFAR provide, and what are their capabilities?

The SPC560P34L1CEFAR integrates two FlexCAN 2.0B interfaces, each with 32 message buffers. One can be configured as a safety port supporting up to 8 Mbit/s at 64 MHz - usable as a second CAN channel when not assigned to safety-critical messaging, enabling dual-bus redundancy in brake or airbag ECUs.

What ADC performance specifications are guaranteed for the SPC560P34L1CEFAR?

The integrated 10-bit SAR ADC achieves <1 µs full-precision conversion time (including sampling), supports up to 12 input channels in LQFP64 configuration, and includes four analog watchdogs with interrupt capability. Input impedance and offset/gain error specs are validated across –40 °C to 125 °C per datasheet Table 30.
