Product details
Overview
SPC560P50L5BEAAR from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 576 KB on-chip Flash (ECC-protected), 40 KB SRAM (ECC-protected), and integrated FlexCAN 2.0B, FlexRay V2.1, LINFlex, DSPI, dual 10-bit ADCs, and FlexPWM - deployed in chassis control units, electronic stability control (ESC), and airbag deployment systems.
For engineers reviewing the SPC560P50L5BEAAR datasheet, SPC560P50L5BEAAR pinout, SPC560P50L5BEAAR application, or SPC560P50L5BEAAR equivalent, key selection criteria include ASIL-B-capable fault collection unit (FCU), Nexus L2+ debug interface, safety port configurable as second CAN or high-speed safety channel (up to 7.5 Mbit/s), and dual-channel FlexRay support at up to 10 Mbit/s.
Technical Context
The SPC560P50L5BEAAR implements a single-issue, 64 MHz e200z0h CPU core compliant with Power Architecture® embedded category and supports Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes 512 KB main Flash with ECC and erase/program controller, plus 64 KB data Flash (4 × 16 KB banks) for EEPROM emulation - both with ECC and independent access paths.
Real-time peripheral coordination is managed via a crossbar switch (XBAR), supporting concurrent access to Flash, SRAM, and peripherals. Safety-critical operation is enabled by programmable watchdog timer (SWT), non-maskable interrupt (NMI), fault collection unit (FCU), and dedicated safety port derived from FlexCAN - configurable for redundant communication or deterministic safety messaging.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560P44L5BEAAR | 448 KB Flash, same 40 KB SRAM, identical peripheral set except reduced FlexRay message object count (16 vs. 32) | Targeted at cost-sensitive ESC variants with lower firmware footprint and reduced FlexRay bandwidth needs | Select when application firmware fits in 448 KB Flash and does not require full FlexRay message buffer depth |
| MC9S12XEQ512MAL | 16-bit HCS12X core, 512 KB Flash, no FlexRay, single CAN, no ECC on Flash/SRAM | Legacy chassis modules requiring pin-compatible upgrade path but lacking ASIL-B support or FlexRay integration | Choose only for brownfield designs where toolchain migration and safety certification are impractical |
Compared with SPC560P44L5BEAAR, the SPC560P50L5BEAAR adds 128 KB Flash and full FlexRay message capacity - critical for next-gen ESC with over-the-air update capability and multi-node FlexRay networks.

FAQ
What is the maximum operating junction temperature for SPC560P50L5BEAAR?
The SPC560P50L5BEAAR is qualified for automotive operation with a maximum junction temperature of 125 °C. Thermal characteristics for the LQFP144 package specify θJA = 30.5 °C/W under JEDEC standard PCB conditions (2s2p copper layers). Derating is required above 105 °C ambient per Section 3.5 of the datasheet.
Does SPC560P50L5BEAAR support JTAG boundary scan?
Yes, the device integrates an IEEE 1149.1 JTAG controller compliant with TAP architecture. It supports boundary scan testing per Table 39 and Figure 22–24 in the datasheet, including instruction register access, data register scan, and IDCODE readback - used for board-level manufacturing test and debug initialization.
Can the safety port operate simultaneously with the primary FlexCAN interface?
No - the safety port shares physical layer resources with the primary FlexCAN module and cannot operate concurrently. When configured as a safety port, the primary FlexCAN interface is disabled. The safety port uses the same CAN protocol stack but adds enhanced timing constraints and error containment logic for ASIL-B use cases.
Is there hardware support for AES encryption in SPC560P50L5BEAAR?
No, the SPC560P50L5BEAAR does not include dedicated AES hardware acceleration. Security functions are limited to CRC computation (for firmware integrity), boot image validation via BAM, and memory protection unit (MPU) enforcement - sufficient for ASIL-B but not cryptographic offload.
