STMicroelectronics SPC560B40L5B6E0Y

Overview

SPC560B40L5B6E0Y 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 Code Flash with ECC, 64 KB Data Flash with ECC, and 48 KB SRAM with ECC, targeting body electronics control in vehicles requiring ASIL-B compliance support.

For engineers reviewing the SPC560B40L5B6E0Y datasheet, SPC560B40L5B6E0Y pinout, SPC560B40L5B6E0Y application, or SPC560B40L5B6E0Y equivalent, key selection considerations include its dual-supply capability (3.3 V/5 V), 6 FlexCAN 2.0B interfaces, time-triggered PWM/ADC synchronization for lighting diagnostics, and Nexus1 debug support in LQFP64 packaging.

Technical Context

The device implements a deterministic real-time execution environment via its e200z0h CPU with hardware memory protection unit (MPU) and cross-triggering unit (CTU) linking ADC conversions to PWM events. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz) with software-controlled FMPLL for flexible domain-specific frequency synthesis.

Peripheral integration includes six 32-bit periodic interrupt timers, four 32-bit system timers, real-time clock, watchdog, and dedicated lighting diagnostic module supporting advanced PWM generation with time-triggered fault detection and synchronized ADC sampling-enabling precise LED driver and relay control in automotive body modules.

FAQ

What is the maximum junction temperature rating for SPC560B40L5B6E0Y?

The device is rated for operation up to +125 °C ambient temperature and has a maximum junction temperature of +150 °C under specified thermal conditions (θ_JA = 45 °C/W for LQFP64). Derating curves and thermal resistance values are provided in Section 3.14 of the datasheet, with mandatory use of recommended PCB copper pour for heatsinking.

Does SPC560B40L5B6E0Y support CAN FD?

No, SPC560B40L5B6E0Y implements FlexCAN 2.0B only, supporting classical CAN up to 1 Mbps. It does not include CAN FD protocol stack or transceiver support. For CAN FD requirements, ST recommends migrating to the SPC58x or SPC57x families, which integrate native CAN FD controllers.

How many independent PWM channels does this MCU provide?

The device supports up to 56 time-triggered I/O channels configurable as PWM, motor control (MC), input capture (IC), or output compare (OC) - with hardware dead-time insertion and complementary output pairs. All channels are synchronized via the CTU for lighting diagnostics and motor phase control.

Is the 64 KB Data Flash suitable for EEPROM emulation?

Yes, the 64 KB Data Flash includes ECC and wear-leveling support, and ST provides certified EEPROM emulation libraries (SPC5Studio) that manage sector rotation, error correction, and atomic write operations - validated for >100k erase/write cycles and data retention over 10 years at 125 °C.
