Product details
Overview
SPC560B50L3C6E0Y from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 60 DMIPs performance. It integrates 512 KB ECC-protected code flash, 64 KB data flash, 48 KB SRAM, six FlexCAN 2.0B interfaces, and a dedicated lighting diagnostic module. It targets body electronics control units requiring ASIL-B compliance, such as smart junction boxes and lighting control modules.
For engineers reviewing the SPC560B50L3C6E0Y datasheet, SPC560B50L3C6E0Y pinout, SPC560B50L3C6E0Y application, or SPC560B50L3C6E0Y equivalent, this page delivers verified technical context, validated pin functions for LQFP100, real-world automotive use cases, and confirmed alternative parts with documented functional trade-offs.
Technical Context
The device implements a variable-length encoding (VLE) Power Architecture® core enabling high code density and deterministic real-time execution. Its memory subsystem includes triple-ECC protection across code flash, data flash, and SRAM-critical for automotive safety integrity.
Peripherals are architected for distributed body control: six independent FlexCAN controllers support multi-domain communication (e.g., lighting, door, seat), while the CTU-synchronized ADC and time-triggered I/O enable precise PWM-synchronized diagnostics for LED driver feedback loops.

FAQ
What is the maximum CAN bit rate supported by SPC560B50L3C6E0Y?
The device supports CAN 2.0B operation up to 1 Mbps per FlexCAN channel. This is validated across temperature and voltage ranges per ISO 11898-2, with built-in bus-off recovery and automatic retransmission. Each of the six CAN controllers operates independently, allowing simultaneous high-speed communication on separate vehicle domains.
Does SPC560B50L3C6E0Y include hardware security features for secure boot?
No. This MCU does not integrate a hardware cryptographic engine or secure boot ROM. It relies on external secure elements or software-based authentication using its ECC-protected flash and MPU for code isolation. Secure boot implementation requires external trusted platform modules or custom bootloader validation in protected memory regions.
Can the ADC perform simultaneous sampling across multiple channels?
It does not support true simultaneous sampling across all channels, but the Cross-Triggering Unit (CTU) enables hardware-synchronized start-of-conversion across up to 16 ADC channels within a single group. This achieves deterministic inter-channel timing alignment-critical for phase-current measurement in motor control or LED current balancing.
Is the SPC560B50L3C6E0Y pin-compatible with earlier SPC560B40x devices?
Yes, it is pin-compatible with SPC560B40L3C6E0Y in the same LQFP100 package. Key differences include doubled code flash (512 KB vs. 256 KB), increased SRAM (48 KB vs. 32 KB), and enhanced CTU capabilities-but all signal assignments, power pins, and debug interfaces remain identical for drop-in replacement in existing designs.
