Product details
Overview
SPC560B40L3C4E0X 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 256 KB ECC-protected Code Flash, 64 KB Data Flash, 48 KB SRAM, six FlexCAN 2.0B interfaces, and a dedicated diagnostic module for lighting control in body electronics systems.
For engineers reviewing the SPC560B40L3C4E0X datasheet, SPC560B40L3C4E0X pinout, SPC560B40L3C4E0X application, or SPC560B40L3C4E0X equivalent, key selection criteria include its -40 to 125 °C operating range, Nexus1 debug interface, LQFP100 package with 75 GPIOs, and support for time-triggered PWM-synchronized ADC measurements in safety-critical lighting modules.
Technical Context
This MCU implements a deterministic real-time architecture with dual-voltage domains (VDD_HV/VDD_BV), hardware memory protection (8-entry MPU), and clock redundancy via FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz) oscillators. Its FMPLL enables precise frequency synthesis for CAN and timer subsystems.
The device features a cross-triggering unit (CTU) linking ADC conversions to PWM events, enabling synchronized diagnostics in LED driver applications. Interrupt handling supports 16 priority levels, NMI, and up to 34 external interrupts-including 18 wakeup-capable lines-for responsive body control logic.

FAQ
What is the maximum ambient temperature rating for SPC560B40L3C4E0X?
The device is qualified for continuous operation from -40 °C to +125 °C ambient temperature per AEC-Q100 Grade 1 specifications. Thermal derating applies above 105 °C case temperature, and the internal temperature sensor monitors die temperature with ±3 °C accuracy for thermal management feedback.
Does SPC560B40L3C4E0X support CAN FD?
No, it implements six FlexCAN 2.0B controllers compliant with ISO 11898-1:2015, supporting data rates up to 1 Mbps and 64 message objects per channel. CAN FD is not supported; this part targets legacy and cost-optimized CAN networks in body electronics rather than high-bandwidth domains.
How many independent PWM channels does it provide?
The MCU supports up to 56 time-triggered I/O channels configurable as PWM, motor control, input capture, or output compare. These are distributed across two 16-bit counter modules, with hardware dead-time insertion and fault protection inputs for motor drive applications.
Is the SPC560B40L3C4E0X pin-compatible with other SPC560x variants?
Yes, all LQFP100-packaged SPC560B/C40x/50x devices share identical pinouts and footprint. This allows direct substitution between SPC560B40L3, SPC560C40L3, SPC560B50L3, and SPC560C50L3 without PCB changes - differing only in flash size, SRAM allocation, and peripheral enablement.
