Product details
Overview
SPC560B40L3B6E0X 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 ECC Data Flash, and 48 KB ECC SRAM, and targets body electronics control including lighting modules and door control units.
For engineers reviewing the SPC560B40L3B6E0X datasheet, SPC560B40L3B6E0X pinout, SPC560B40L3B6E0X application, or SPC560B40L3B6E0X equivalent, key selection criteria include its dual-supply operation (3.3 V/5 V), -40 to 125 °C temperature grade, FlexCAN 2.0B interfaces, time-triggered I/O for PWM-synchronized ADC diagnostics, and Nexus1 debug support.
Technical Context
This MCU implements a deterministic real-time architecture with 16 priority-level interrupt controller, non-maskable interrupt (NMI), and up to 34 external interrupt sources-including 18 wakeup-capable lines. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), SIRC (128 kHz), and software-controlled FMPLL for flexible domain-specific frequency synthesis.
The peripheral set includes six FlexCAN controllers (each with 64 message objects), four LINFlex/UART channels, three DSPI/I²C interfaces, six-channel periodic interrupt timers, and a dedicated diagnostic module supporting advanced PWM generation, time-triggered diagnostics, and CTU-synchronized ADC measurements for lighting control.
