Product details
Overview
SPC560P50L5CEFBY 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 (<1 µs conversion), and FlexPWM - designed for chassis control and functional safety applications including electronic braking and steering systems.
For engineers reviewing the SPC560P50L5CEFBY datasheet, SPC560P50L5CEFBY pinout, SPC560P50L5CEFBY application, or SPC560P50L5CEFBY 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 (up to 10 Mbit/s) in the 576 KB variant.
Technical Context
The SPC560P50L5CEFBY implements a single-issue, 64 MHz e200z0h CPU core compliant with Power Architecture® embedded category and supporting Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes ECC-protected 576 KB Flash, 64 KB data flash (4 × 16 KB banks) for EEPROM emulation, and 40 KB SRAM - all accessible via a crossbar switch (XBAR) enabling concurrent peripheral access.
Real-time control is enabled by two eTimer units (6×16-bit cascadable timers each, quadrature decode, double-buffered I/O), a programmable watchdog timer, non-maskable interrupt, and a dedicated Fault Collection Unit (FCU) for ASIL-B-compliant failure detection. The safety port operates as a hardware-isolated FlexCAN instance with independent message RAM and timing, usable either as redundant CAN or dedicated safety channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive chassis control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560P44L5CEFBY | 448 KB Flash, same LQFP144 package, identical peripheral set except reduced Flash capacity | Targeted at cost-optimized chassis modules with smaller firmware footprints (e.g., basic ESC without advanced features) | Select when firmware size ≤400 KB and no requirement for data flash EEPROM emulation beyond 32 KB |
| MC9S12XEQ512 | 16-bit HCS12X core, 512 KB Flash, no FlexRay or safety port; uses BDM debug instead of Nexus L2+ | Legacy platform migration path; lacks ASIL-B-certifiable safety mechanisms and modern time-triggered networking | Choose only for backward-compatible upgrades where FlexRay/FlexCAN safety port is not required and toolchain continuity is critical |
Compared with SPC560P44L5CEFBY, the SPC560P50L5CEFBY provides 128 KB additional Flash for complex safety routines and data logging, while MC9S12XEQ512 lacks hardware safety features and modern deterministic networking - making SPC560P50L5CEFBY the sole option meeting current ASIL-B chassis control requirements.

FAQ
What is the maximum operating temperature range for SPC560P50L5CEFBY?
The SPC560P50L5CEFBY is qualified for AEC-Q100 Grade 1 operation, supporting ambient temperatures from –40 °C to +125 °C. Junction temperature limits are defined in Section 3.5 of the datasheet, with thermal resistance θJA = 28.5 °C/W for LQFP144 package under standard JEDEC PCB conditions.
Does SPC560P50L5CEFBY support ISO 26262 ASIL-B certification out of the box?
The device includes hardware features required for ASIL-B decomposition - ECC memory, Fault Collection Unit (FCU), safety port, and Nexus L2+ debug - but full certification requires system-level integration, safety manual implementation, and tool qualification per ISO 26262 Part 6. ST provides safety documentation (SPC560P50L5 Safety Manual, AN4472) to support this process.
Can the safety port be used simultaneously with the main FlexCAN interface?
Yes - the safety port operates as an independent FlexCAN instance with its own message RAM, clock domain, and dedicated pins (SAFE_CAN_TX/RX). It shares no registers or memory with the main FlexCAN, enabling concurrent operation for redundancy or functional separation (e.g., main CAN for diagnostics, safety port for brake commands).
What boot options are supported at power-on reset?
The SPC560P50L5CEFBY supports three boot modes selected via BOOT[1:0] pins: internal Flash execution, CAN/UART bootloader (BAM mode), or external memory interface. The BAM mode enables field firmware recovery via CAN or UART without JTAG, with configurable signature verification and timeout handling per ST Application Note AN4220.
