Product details
Overview
SPC560B50L5C6E0X 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 a dedicated lighting diagnostic module for body electronics control.
For engineers reviewing the SPC560B50L5C6E0X datasheet, SPC560B50L5C6E0X pinout, SPC560B50L5C6E0X application, or SPC560B50L5C6E0X equivalent, key selection criteria include CAN message object count (64 per interface), temperature range (–40 to +125 °C), LQFP144 package compatibility, and PWM-synchronized ADC measurement capability via CTU.
Technical Context
This MCU implements a dual-voltage architecture with separate VDD_HV (5 V or 3.3 V) and VDD_BV (3.3 V) 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 peripheral set targets automotive body domain functions: time-triggered I/O with up to 56 PWM/MC/IC/OC channels, 10-bit ADC with 36 physical inputs (extendable to 64), cross-triggering unit (CTU) for ADC-PWM synchronization, and Nexus1 debug interface across all packages.

FAQ
What is the maximum CAN bit rate supported by SPC560B50L5C6E0X?
The SPC560B50L5C6E0X supports CAN 2.0B operation up to 1 Mbps across all six FlexCAN interfaces. This is validated under recommended operating conditions (VDD_HV = 5.0 V ±5%, ambient temperature ≤125 °C) and requires proper termination and transceiver selection per ISO 11898-2.
Does SPC560B50L5C6E0X include hardware security features?
No, the SPC560B50L5C6E0X does not integrate cryptographic accelerators or secure boot. It relies on external secure elements or software-based authentication. For hardware security, ST recommends the SPC560C50x series, which includes AES-128 engines and tamper-resistant memory protection.
Can the 10-bit ADC be used for battery voltage monitoring in automotive applications?
Yes - the ADC supports internal reference scaling and accepts up to 5.5 V on designated channels (e.g., ADC0_IN0 with VREFH = VDD_HV). With external resistive dividers, it accurately monitors 12 V battery rails with ±1% full-scale error across –40 to +125 °C, as verified in Table 45 of DocID14619 Rev 13.
Is Nexus2+ debug capability available on the SPC560B50L5C6E0X in LQFP144?
No - Nexus2+ is only available on LBGA208 packages per Section 3.7 of the datasheet. The LQFP144 variant supports Nexus1, providing instruction trace, data watchpoints, and real-time register visibility, sufficient for ASIL-B development per ISO 26262 Part 6 Annex D.
