STMicroelectronics SPC560C40L3C6E0X

Overview

SPC560C40L3C6E0X from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 512 KB ECC-protected code flash, 64 KB data flash, and 48 KB SRAM. It integrates six FlexCAN 2.0B interfaces, four LINFlex/UART channels, three DSPI/I²C peripherals, and a dedicated lighting diagnostic module for body electronics control systems.

For engineers reviewing the SPC560C40L3C6E0X datasheet, SPC560C40L3C6E0X pinout, SPC560C40L3C6E0X application, or SPC560C40L3C6E0X equivalent, key selection criteria include CAN message object count (64 per interface), PWM-synchronized ADC measurement capability, ultra-low-power standby with RTC/CAN monitoring, and -40 to 125 °C operation in LQFP100 package.

Technical Context

This MCU implements a variable-length encoding (VLE) Power Architecture® core enabling high code density and deterministic real-time execution. Its interrupt subsystem supports 16 priority levels, 34 external interrupts (18 wakeup-capable), and non-maskable interrupt (NMI) handling for safety-critical automotive functions.

The clock system combines four oscillators (FXOSC 4–16 MHz, SXOSC 32 kHz, FIRC 16 MHz, SIRC 128 kHz) with software-controlled FMPLL and clock monitor unit (CMU) for robust timing integrity. The cross-triggering unit (CTU) enables synchronized PWM generation and ADC sampling for lighting diagnostics.

FAQ

What is the maximum operating frequency of the SPC560C40L3C6E0X CPU core?

The e200z0h CPU core operates at a maximum frequency of 64 MHz, delivering up to 60 DMIPs. This frequency is achieved using the FMPLL with input from the fast external crystal oscillator (4–16 MHz) or fast internal RC oscillator (16 MHz), and is validated across the full -40 to 125 °C temperature range per datasheet Section 3.23.

Does the SPC560C40L3C6E0X support CAN FD or only classical CAN 2.0B?

The SPC560C40L3C6E0X supports only Classical CAN 2.0B, not CAN FD. Each of its six FlexCAN modules implements 2.0B active protocol with 64 configurable message objects, hardware acceptance filtering, and loopback self-test modes - confirmed in Section 1.2 and Table 3 of the datasheet.

How many GPIO pins are available in the LQFP100 package variant?

The SPC560C40L3C6E0X in LQFP100 provides 75 GPIO pins, as specified in the "Features" section of the datasheet. This count excludes dedicated power, ground, reset, and oscillator pins, and includes all multiplexed functional ports usable as general-purpose inputs/outputs with configurable pull-up/down and slew rate control.

Is the SPC560C40L3C6E0X qualified to AEC-Q100 Grade 0 or Grade 1?

The SPC560C40L3C6E0X is qualified to AEC-Q100 Grade 1 (-40 to 125 °C), as stated in the device summary table and confirmed by its operating temperature specification. Grade 0 qualification is not supported; this part is intended for under-hood and cabin-mounted body electronics, not extreme-environment engine control applications.
