STMicroelectronics AEK-MCU-C4MLIT1

Overview

AEK-MCU-C4MLIT1 from STMicroelectronics is an automotive-grade MCU discovery board built around the SPC58EC80E5 - a 32-bit Power Architecture e200z4d dual-core microcontroller with 4224 kB flash, 128 kB data flash, ASIL-B safety compliance, Hardware Secure Module (EVITA Medium), and two integrated ISO CAN FD transceivers. It targets rapid evaluation of automotive control functions including body electronics, gateway modules, and chassis subsystems.

For engineers reviewing the AEK-MCU-C4MLIT1 datasheet, AEK-MCU-C4MLIT1 pinout, AEK-MCU-C4MLIT1 application, or AEK-MCU-C4MLIT1 equivalent, key selection criteria include ASIL-B qualification, dual-core debug access via PLS UDE, AutoDevKit™ interoperability, on-board CAN FD physical layer, and SPC5-STUDIO-integrated code generation for peripheral configuration and secure boot development.

Technical Context

The board implements full hardware access to both e200z4d cores of the SPC58EC80E5, enabling lockstep or independent execution modes for functional safety partitioning. It routes all GPIOs, UART, SPI, I²C, and ADC channels to a standardized 4×37-pin AutoDevKit™ extension connector, supporting modular system prototyping.

On-board resources include two ISO CAN FD transceivers compliant with ISO 11898-2:2016, a USB virtual COM port (mini-B interface), three user push buttons, three LEDs, two potentiometers for analog input testing, and 12 VDC power input with automotive-grade ST components throughout.

FAQ

Does AEK-MCU-C4MLIT1 support JTAG or SWD debugging?

No - it uses the PLS Universal Debug Engine (UDE) via dedicated debug header compatible with the SPC58EC80E5's Nexus Class 3+ interface. This provides real-time trace, multi-core synchronization, and secure debug authentication required for ASIL-B development, unlike standard JTAG/SWD.

Is the USB virtual COM port isolated from the MCU's main UART peripherals?

Yes - the USB-to-UART bridge connects exclusively to the SPC58EC80E5's dedicated debug UART (UART_D), leaving all other UART instances (UART_0–UART_3) fully available for application use, including CAN FD gateway routing or diagnostic communication.

Can the onboard potentiometers be used for production calibration?

No - they are evaluation-only analog inputs routed to ADC channels for quick signal verification and firmware tuning during development. Production systems must implement calibrated external sensors or trimmable references meeting AEC-Q200 requirements.

What AutoDevKit™ functional boards are natively supported out-of-the-box?

The board supports ST's AEK-LED-001 (LED driver), AEK-MOT-201 (DC motor driver), AEK-MOT-301 (stepper driver), AEK-WLC-001 (wireless charging), and AEK-POW-201 (digital power supply) via the 4×37 connector and AutoDevKit plugin libraries - all with pre-integrated BSPs and HAL drivers in SPC5-STUDIO.
