FAQ

What is the maximum operating frequency of the e200z0h core in SPC560P50L5BEFAY?

The e200z0h core operates at a maximum frequency of 64 MHz, confirmed in the device summary and electrical characteristics section of the official datasheet (Doc ID 14723 Rev 9). This frequency is achieved using the on-chip FMPLL with external crystal or clock input, and is sustained across the full automotive temperature range (–40 °C to 125 °C).

Does SPC560P50L5BEFAY support JTAG and Nexus debug interfaces simultaneously?

No - the device implements a shared debug port: IEEE 1149.1 JTAG is used for boundary scan and basic programming, while Nexus L2+ operates over the same physical pins (TCK/TMS/TDI/TDO) in debug mode. The debug mode is selected via boot configuration pins; Nexus requires external debugger support (e.g., Lauterbach TRACE32) and cannot be active concurrently with JTAG boundary scan.

How is functional safety supported in the memory subsystem?

Functional safety is enforced via ECC on all major memory blocks: 512 KB code Flash, 64 KB data Flash, and 40 KB SRAM each implement Hamming-code ECC for single-bit correction and double-bit detection. The Error Correction Status Module (ECSM) monitors ECC errors and triggers interrupts or NMI, and is integrated with the Fault Collection Unit (FCU) for ASIL-B-compliant fault logging and response.

What is the role of the safety port FlexCAN interface?

The safety port is a physically separate FlexCAN instance with dedicated message RAM, clock domain, and error counters - not a software-configured mode of the primary FlexCAN. It supports up to 7.5 Mbit/s and is intended for time-critical, safety-relevant communication (e.g., ESC actuator commands), isolated from standard vehicle network traffic handled by the main FlexCAN interface.
