Product details
Overview
SPC560B50L3B6E0X from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 60 DMIPs performance, 512 KB ECC-protected code flash, 64 KB data flash, and 48 KB SRAM - deployed in body control modules for headlight automation, door module sequencing, and HVAC actuator control.
For engineers reviewing the SPC560B50L3B6E0X datasheet, SPC560B50L3B6E0X pinout, SPC560B50L3B6E0X application, or SPC560B50L3B6E0X equivalent, key selection criteria include FlexCAN 2.0B interface count (6 channels), 10-bit ADC with CTU cross-triggering (up to 36 channels), dedicated lighting diagnostic PWM engine, and -40°C to +125°C operation in LQFP100 package.
Technical Context
This MCU implements a variable-length encoding (VLE) e200z0h CPU core with Nexus1 debug support and optional Nexus2+ in emulation packages. It integrates six independent FlexCAN 2.0B controllers with 64-message object buffers each, enabling concurrent CAN FD-ready communication across multiple vehicle domains.
The peripheral set includes a time-triggered I/O subsystem with 56-channel 16-bit counter/timer supporting PWM, input capture, output compare, and motor control - synchronized via cross-triggering unit (CTU) to ADC conversions for lighting diagnostics and sensor sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | e200z0h Power Architecture® core with VLE, 64 MHz max, 60 DMIPs - enables deterministic real-time execution for ASIL-B-compliant body electronics tasks. |
| Flash Memory | 512 KB code flash + 64 KB data flash, both with ECC - supports robust firmware storage and parameter logging in harsh automotive environments. |
| SRAM | 48 KB SRAM with ECC - provides fault-tolerant runtime data buffering for safety-critical control loops. |
| ADC | 10-bit SAR ADC with up to 36 channels, CTU-synchronized sampling - delivers precise analog sensing for ambient light, temperature, and position feedback in lighting and HVAC systems. |
| FlexCAN Interfaces | 6 × FlexCAN 2.0B controllers, each with 64 message objects - allows full CAN network partitioning (e.g., separate buses for lighting, door, seat, HVAC, gateway). |
| Operating Temperature | -40°C to +125°C - qualified for under-hood and cabin-mounted automotive body control units without derating. |
| Supply Voltage | Single 3.3 V or 5 V supply - simplifies power architecture by eliminating dual-rail regulators in cost-sensitive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B50L5B6E0X | LQFP144 package (123 GPIO), same core/peripherals but larger footprint and higher pin count | Required when >75 GPIO or additional CAN/LIN channels needed (e.g., full-featured gateway) | Select only if LQFP144 mechanical layout and thermal margin are available; otherwise LQFP100 offers optimal cost/size balance. |
| SPC560C50L3B6E0X | Same LQFP100 package but with enhanced clock monitor unit (CMU) and extended watchdog features per ISO 26262 ASIL-B | Preferred for new designs targeting functional safety certification where CMU fault injection testing is mandated | Choose SPC560C50L3B6E0X if ASIL-B certification evidence (FMEDA, safety manual) is contractually required; SPC560B50L3B6E0X remains valid for legacy-compliant body nodes. |
Compared with SPC560B50L3B6E0X, the L5 variant trades package size for scalability, while the C50 variant adds certified safety mechanisms - making the B50 the optimal choice for cost-sensitive, volume-production body control units where existing qualification suffices.

FAQ
What is the maximum operating frequency of the e200z0h core in SPC560B50L3B6E0X?
The e200z0h core operates at a maximum frequency of 64 MHz, delivering up to 60 DMIPs. This frequency is achieved using the FMPLL with either the 4–16 MHz external crystal oscillator or the 16 MHz internal FIRC, and is fully characterized across the -40°C to +125°C temperature range per ST's production data.
Does SPC560B50L3B6E0X support CAN FD?
No, SPC560B50L3B6E0X implements FlexCAN 2.0B controllers only, supporting classical CAN up to 1 Mbps. It does not include CAN FD protocol handling, bit-rate switching, or extended data length frames - confirmed in the peripheral summary (Section 3.27.1) and register-level documentation of the MCR and CTRL1 registers.
How many ADC channels are accessible in the LQFP100 package?
The LQFP100 package provides access to 36 ADC input channels, mapped to dedicated pins including ADC0_IN0 through ADC0_IN15 and ADC1_IN0 through ADC1_IN20. This count is explicitly listed in Table 6 (Functional port pin descriptions) and verified in the pin multiplexing matrix of Section 3.6.
Is the 64 KB data flash truly EEPROM-emulated with wear leveling?
Yes - the 64 KB data flash supports EEPROM emulation via ST's SPC5 Flash Driver Library, which implements hardware-assisted wear leveling across 128-byte sectors. Endurance is rated at ≥100,000 write/erase cycles with data retention guaranteed for 10 years at 125°C, as specified in Table 30 (Flash module life) and Section 3.19.1.
