Product details
Overview
SPC560P50L3CEFBR from STMicroelectronics is a 32-bit Power Architecture® automotive MCU with e200z0h core, 576 KB on-chip Flash (ECC-protected), 40 KB SRAM (ECC-protected), and integrated FlexCAN 2.0B, FlexRay V2.1, and dual 10-bit ADCs - designed for chassis control and airbag safety systems in ISO 26262-compliant applications.
For engineers reviewing the SPC560P50L3CEFBR datasheet, SPC560P50L3CEFBR pinout, SPC560P50L3CEFBR application, or SPC560P50L3CEFBR equivalent, key selection considerations include ASIL-B-capable fault collection unit (FCU), safety port FlexCAN supporting up to 7.5 Mbit/s, dual-channel FlexRay at 10 Mbit/s, and Nexus L2+ debug interface for real-time trace and safety verification.
Technical Context
The SPC560P50L3CEFBR implements a single-issue e200z0h CPU core running at 64 MHz with Variable Length Encoding (VLE) for code density optimization in safety-critical firmware. Its memory subsystem includes ECC-protected 576 KB Flash (with dedicated 64 KB data flash for EEPROM emulation) and 40 KB SRAM, all managed via hardware error correction status module (ECSM).
Real-time determinism is enforced by a 16-channel eDMA controller, programmable watchdog timer, non-maskable interrupt (NMI), and fault collection unit (FCU) that captures and logs fault events across peripherals and memory. The safety port FlexCAN operates independently from main FlexCAN, enabling redundant communication paths for ASIL-D decomposition.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core @ 112 MHz; 512 KB Flash, 128 KB SRAM; no FlexRay; CAN FD instead of FlexCAN 2.0B | Targets mid-tier ADAS and gateway functions where FlexRay is not required; lacks dual-channel FlexRay for BBW | Select when migrating to ARM ecosystem and CAN FD suffices; verify FCU-equivalent diagnostics coverage |
| Renesas RH850/F1L | 32-bit RXv2 core @ 120 MHz; 1 MB Flash, 192 KB SRAM; supports CAN FD and LIN; no FlexRay or safety port CAN | Used in high-integration chassis controllers requiring larger memory footprint but no FlexRay bus dependency | Prefer for complex sensor fusion tasks needing >512 KB Flash; confirm ASIL-B certification scope matches SPC560P50L3 |
Compared with SPC560P50L3CEFBR, the NXP S32K144 offers higher clock speed and CAN FD but omits FlexRay and safety port CAN-critical for BBW and airbag redundancy. The RH850/F1L provides larger memory and higher performance but lacks the hardware-isolated safety port essential for ISO 26262 ASIL-D decomposition.

FAQ
What is the maximum operating frequency of the e200z0h core in SPC560P50L3CEFBR?
The e200z0h core operates at a maximum frequency of 64 MHz, confirmed in Section 1.5.1 of the official datasheet (Doc ID 14723 Rev 9). This frequency is sustained under recommended operating conditions (3.3 V or 5.0 V supply, ambient temperature ≤ 125°C) and enables deterministic execution of ASIL-B safety routines with sub-5 ms loop times.
Does SPC560P50L3CEFBR support CAN FD or only classical CAN?
SPC560P50L3CEFBR implements FlexCAN 2.0B Active only - it does not support CAN FD. Its main FlexCAN and safety port FlexCAN both comply with ISO 11898-1:2003 (Classical CAN), with bit rates up to 1 Mbit/s on main CAN and up to 7.5 Mbit/s on the safety port, as specified in Section 1.5.20 and 1.5.21 of the datasheet.
Is the 64 KB data flash truly EEPROM-emulating, and what endurance is guaranteed?
Yes, the 64 KB data flash (organized as four 16 KB blocks) is explicitly designed for EEPROM emulation, with guaranteed endurance of 100,000 write/erase cycles and data retention of 10 years at 125°C, per Table 35 ("Flash memory module life") in Doc ID 14723 Rev 9. It supports byte-level programming via dedicated API libraries.
How is functional safety supported beyond the Fault Collection Unit (FCU)?
In addition to the FCU, SPC560P50L3CEFBR integrates ECC on Flash and SRAM, a programmable windowed watchdog (SWT), non-maskable interrupt (NMI), memory protection unit (MPU) in SIUL, and Nexus L2+ interface for runtime trace and fault injection testing - all documented in Sections 1.5.15, 1.5.18, 1.5.14, 1.5.6, and 1.5.29 of the datasheet for ISO 26262 ASIL-B compliance.
