Product details
Overview
SPC560P50L5BEAAY from STMicroelectronics is a 32-bit Power Architecture® automotive MCU featuring a 64 MHz e200z0h CPU core, 576 KB on-chip Flash memory with ECC, 40 KB SRAM with ECC, and integrated FlexCAN, FlexRay, LINFlex, DSPI, ADC, and FlexPWM peripherals - deployed in chassis control units for brake-by-wire and electronic stability control systems.
For engineers reviewing the SPC560P50L5BEAAY datasheet, SPC560P50L5BEAAY pinout, SPC560P50L5BEAAY application, or SPC560P50L5BEAAY equivalent, this page delivers verified technical context, validated pin functions, automotive-grade fail-safe features, and real-world timing and interface constraints for functional safety (ASIL-B) system integration.
Technical Context
The device implements a single-issue e200z0h core compliant with Power Architecture® embedded category and supports Variable Length Encoding (VLE) for code density optimization. It integrates a crossbar switch (XBAR) for concurrent peripheral access and an enhanced DMA (eDMA) controller with 16 channels to offload CPU during high-bandwidth data transfers.
Fail-safe operation is enforced via programmable watchdog timer (SWT), non-maskable interrupt (NMI), fault collection unit (FCU), and ECC-protected memory subsystems. The safety port extends FlexCAN functionality to support up to 7.5 Mbit/s communication with dual-message-object arbitration for ASIL-B–compliant chassis domain controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive chassis MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560P44L5BEAAY | 448 KB Flash, same LQFP144 package, identical peripheral set except reduced Flash capacity | Suitable for cost-optimized chassis modules with smaller firmware footprints (e.g., basic ESC variants) | Select when firmware size ≤400 KB and no future OTA update headroom is required |
| MPC5604B | Freescale (now NXP) 64 MHz e200z0h core, 512 KB Flash, no FlexRay, only one CAN channel | Lacks FlexRay and safety-port CAN; limited to ASIL-A applications without dual-bus redundancy | Choose only if FlexRay is unused and system-level redundancy is implemented externally |
Compared with SPC560P50L5BEAAY, the SPC560P44L5BEAAY offers identical safety architecture but less Flash for firmware growth margin, while the MPC5604B lacks FlexRay and dual-CAN safety port - making it unsuitable for new ASIL-B chassis designs requiring native protocol diversity and redundancy.

FAQ
What is the maximum operating junction temperature for SPC560P50L5BEAAY?
The device is qualified for automotive operation with a maximum junction temperature of 125 °C, validated per AEC-Q100 Grade 1 requirements. Thermal resistance (θJA) is 29.5 °C/W for the LQFP144 package under standard JEDEC 2S2P board conditions, enabling reliable operation in under-hood environments without forced airflow.
Does SPC560P50L5BEAAY support bootloading over CAN?
Yes - it includes an on-chip CAN/UART bootstrap loader with Boot Assist Module (BAM), allowing firmware updates via CAN 2.0B frames without external programming hardware. The loader supports secure checksum verification and segmented memory writes aligned to Flash sector boundaries.
How many message objects does the FlexRay module support?
The FlexRay module supports 32 message objects, configurable across static and dynamic segments per FlexRay v2.1 specification. All 32 objects are accessible in both single- and dual-channel modes, with hardware timestamping and cyclic redundancy check (CRC) generation/verification enabled per message.
Is the internal 16 MHz RC oscillator calibrated for production use?
Yes - the 16 MHz RC oscillator is factory-trimmed to ±1% accuracy across –40 °C to 125 °C and supports clock failover to main oscillator or external source. It serves as a reliable backup clock for safety monitor functions and low-power wake-up scenarios where crystal startup delay is unacceptable.
