FAQ
What is the maximum operating temperature range for SPC560P50L5BEFAR?
The SPC560P50L5BEFAR is qualified for AEC-Q100 Grade 1 operation, supporting junction temperatures from –40 °C to +125 °C. Thermal characteristics are specified in Doc ID 14723 Rev 9 Table 12, with θJA = 26.5 °C/W for LQFP144 under standard JEDEC 2S2P board conditions.
Does SPC560P50L5BEFAR support CAN FD?
No. The SPC560P50L5BEFAR integrates FlexCAN 2.0B Active (not CAN FD), supporting up to 1 Mbit/s classical CAN. Its safety port operates at up to 7.5 Mbit/s but remains protocol-compatible with CAN 2.0B only-no CAN FD frame format or bitrate switching capability is implemented.
How is functional safety certification documented for this MCU?
STMicroelectronics provides ISO 26262 ASIL-B ready documentation for the SPC560P50L5BEFAR, including FMEDA reports, safety manuals, and diagnostic coverage analysis. These materials are accessible via ST's Automotive Functional Safety Portal under product-specific safety archives (SPC560P50L5).
Can the 64 KB data flash be used for EEPROM emulation in production firmware?
Yes. The device includes 64 KB (4 × 16 KB blocks) of on-chip data flash with ECC and wear-leveling support, explicitly designed for EEPROM emulation. ST provides the SPC56ELK EEPROM Emulation Library (EEEL) with drivers, sector management, and atomic write/erase APIs validated for automotive duty cycles.
