Product details
Overview
SPC560B50L3C6E0X 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 SPC560B50L3C6E0X datasheet, SPC560B50L3C6E0X pinout, SPC560B50L3C6E0X application, or SPC560B50L3C6E0X equivalent, key selection criteria include CAN message object count (64 per interface), -40 to 125 °C operating range, LQFP100 package with 75 GPIO, and hardware CTU-synchronized PWM/ADC timing for lighting diagnostics.
Technical Context
This MCU implements a dual-voltage domain architecture (VDD_HV/VDD_BV) supporting single 5 V or 3.3 V supply operation, with integrated FMPLL for clock synthesis and independent FIRC/SIRC oscillators enabling ultra-low-power standby with RTC and CAN monitoring active. The Nexus1 debug interface is standard; Nexus2+ requires LBGA208 packaging.
The peripheral set includes a 10-bit ADC with up to 36 channels (extendable to 64 via external mux), cross-triggering unit (CTU) for synchronized PWM generation and ADC sampling, and six-channel 32-bit periodic interrupt timers plus real-time clock - all designed for deterministic timing in automotive body control units.

FAQ
What is the maximum CAN bit rate supported by SPC560B50L3C6E0X?
The device supports up to 1 Mbps CAN FD-capable physical layer signaling through its six FlexCAN 2.0B interfaces. Each interface implements full CAN protocol handling including error framing, automatic retransmission, and bus-off recovery - validated per ISO 11898-1 with external transceivers such as TJA1043.
Does SPC560B50L3C6E0X include hardware security features?
No - this variant lacks embedded cryptographic accelerators, secure boot ROM, or tamper-detection circuitry found in the SPC560C50x series. It meets ASIL-B functional safety requirements via ECC memory, lockstep peripherals, and diagnostic firmware libraries, but does not provide hardware-enforced security primitives.
Can the ADC operate synchronously with PWM outputs?
Yes - the Cross-Triggering Unit (CTU) enables hardware-level synchronization between PWM edge events and ADC start-of-conversion triggers. This eliminates software jitter and ensures repeatable sampling timing within ±1 system clock cycle, critical for closed-loop LED current regulation.
What debug interface is included on SPC560B50L3C6E0X?
The device integrates Nexus1 debug architecture as standard, supporting real-time trace, breakpoints, and memory inspection via JTAG. Nexus2+ is only available on LBGA208 packages and is not implemented on this LQFP100 variant.
