Product details
Overview
SPC560B50L5C6E0Y from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 60 DMIPs performance and Variable Length Encoding (VLE). It integrates 512 KB ECC-protected code flash, 64 KB data flash, 48 KB SRAM, six FlexCAN 2.0B interfaces, and dedicated lighting diagnostic modules for body electronics control.
For engineers reviewing the SPC560B50L5C6E0Y datasheet, SPC560B50L5C6E0Y pinout, SPC560B50L5C6E0Y application, or SPC560B50L5C6E0Y equivalent, key selection criteria include CAN interface count (6x), automotive-grade temperature range (−40 to +125 °C), LQFP144 package compatibility, and integrated CTU-synchronized PWM/ADC for lighting diagnostics.
Technical Context
This MCU implements a dual-voltage architecture with separate VDD_HV (5 V or 3.3 V) and VDD_BV domains, supporting ultra-low-power standby with RTC, SRAM retention, and CAN monitoring. Its clock system includes FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), SIRC (128 kHz), and software-controlled FMPLL for flexible frequency synthesis.
The interrupt subsystem supports 16 priority levels, NMI, and up to 34 external interrupts-including 18 wakeup-capable lines-while the 16-bit counter time-triggered I/O unit delivers up to 56 channels with PWM, motor control, input capture, and output compare functions, all synchronized via cross-triggering unit (CTU).

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B40L5C6E0Y | Same LQFP144 package but with 256 KB code flash and no data flash; lacks dedicated lighting diagnostic module | Suitable for cost-sensitive BCMs without advanced LED control; not qualified for ASIL-B lighting functions | Select when flash footprint and diagnostic features are non-critical and BOM cost reduction is prioritized |
| SPC560C50L5C6E0Y | Same flash/SRAM specs but adds EEPROM emulation and enhanced LINFlex UART features; identical pinout and thermal profile | Better suited for gateway functions requiring non-volatile parameter storage and multi-protocol serial bridging (LIN/CAN/UART) | Choose when EEPROM-like data retention and expanded serial interface flexibility outweigh minor cost premium |
Compared with SPC560B40L5C6E0Y, this part adds 256 KB flash capacity and lighting diagnostics essential for ASIL-B LED control; versus SPC560C50L5C6E0Y, it trades EEPROM emulation for lower gate count and reduced test complexity in lighting-dedicated designs.

FAQ
What is the maximum operating frequency of the e200z0h core in SPC560B50L5C6E0Y?
The e200z0h CPU operates at a maximum frequency of 64 MHz, delivering up to 60 DMIPs. This frequency is achieved using the FMPLL with input from the fast external crystal oscillator (FXOSC) or fast internal RC oscillator (FIRC), and is validated across the full −40 °C to +125 °C temperature range per AEC-Q100 requirements.
Does SPC560B50L5C6E0Y support JTAG debugging?
Yes, the device supports JTAG boundary scan and Nexus1 debug interface on all packages. JTAG is used for programming, emulation, and structural testing, while Nexus1 provides real-time trace, breakpoints, and memory access - both compliant with IEEE 1149.1 and Nexus Class 1 standards for automotive development workflows.
How many CAN message objects does each FlexCAN interface support?
Each of the six FlexCAN 2.0B interfaces supports up to 64 message objects, configurable as transmit, receive, or FIFO buffers. These objects include acceptance masking, priority arbitration, and timestamping - enabling complex multi-node body networks with guaranteed latency for critical messages like door lock status or hazard light commands.
Is the 512 KB code flash field-programmable and ECC-enabled?
Yes, the 512 KB code flash is fully field-programmable via standard Flash programming algorithms and includes single-bit error correction and double-bit error detection (SEC-DED) using dedicated hardware ECC logic. This ensures data integrity during over-the-air (OTA) updates and runtime execution in harsh automotive environments.
