FAQ
What is the maximum ambient temperature rating for the SPC5748GK0AMMJ6?
The SPC5748GK0AMMJ6 is qualified for operation from –40 °C to +125 °C ambient temperature, with junction temperature up to +150 °C. This rating is validated per AEC-Q100 Grade 1 and supports under-hood deployment in engine control and transmission applications where thermal margins are critical. The device includes integrated thermal monitoring and automatic throttling via the System Protection Unit to maintain reliability within this range. SPC5748GK0AMMJ6 thermal attributes are documented in Section 7 of the official NXP datasheet Rev. 5.
Does the SPC5748GK0AMMJ6 support CAN FD on all eight FlexCAN modules?
Yes, all eight FlexCAN3 modules in the SPC5748GK0AMMJ6 support CAN FD protocol, including bit rate switching, extended data length (up to 64 bytes), and CRC-17 error detection. This capability is confirmed in Table 1 of the MPC5748G Family Comparison and enabled by the integrated FlexCAN3 IP block. SPC5748GK0AMMJ6 leverages this to aggregate high-bandwidth sensor data from ADAS ECUs while maintaining legacy CAN 2.0B compatibility on shared buses.
How does the SPC5748GK0AMMJ6 implement end-to-end ECC protection?
The SPC5748GK0AMMJ6 applies SECDED (Single Error Correction, Double Error Detection) ECC across all 64-bit data and 29-bit address paths for every bus transaction initiated by any master-including both e200Z4 cores, e200Z2 core, eDMA, and debug interfaces. This covers flash reads/writes, SRAM accesses, and peripheral register transfers. SPC5748GK0AMMJ6 ECC logic is embedded in the memory controller and crossbar switch, requiring no software intervention and delivering zero-latency correction for transient faults.
What clock sources are available for the SPC5748GK0AMMJ6 real-time counter (RTC)?
SPC5748GK0AMMJ6 supports RTC operation using either the 32.768 kHz SXOSC crystal oscillator or the internal 128 kHz SIRC oscillator. The SXOSC path provides ±20 ppm accuracy for calendar-time applications, while the SIRC enables RTC wake-up from ultra-low-power stop modes with typical current draw below 1 µA. Both sources feed the RTC/API module independently of the main FMPLL, ensuring timekeeping continuity during system resets or PLL reconfiguration. SPC5748GK0AMMJ6 clock routing is detailed in Section 6.2 of the datasheet.
Is the SPC5748GK0AMMJ6 pin-compatible with other MPC5748G family members in the same package?
Yes, all MPC5748G variants in the 256-pin MAPBGA package-including SPC5748GK0AMMJ6, MPC5748CK0AMMJ6, and MPC5747GK0AMMJ6-share identical pinouts and electrical characteristics. This allows hardware reuse across gateway, body control, and chassis variants by changing only flash content and configuration bits. SPC5748GK0AMMJ6 pin compatibility is guaranteed per NXP's package definition documents and validated in the "Package pinouts and signal descriptions" section (Section 9.1) of the MPC5748G datasheet Rev. 5.
