STMicroelectronics AEK-MCU-C4MINI1

Overview

AEK-MCU-C4MINI1 from STMicroelectronics is an automotive-grade evaluation board built around the SPC58EC80E5 32-bit Power Architecture e200z4d dual-core MCU (180 MHz ×2), featuring 4224 kB flash, 128 kB data flash, integrated CAN FD (×3), LIN transceiver, VNH7040AY H-bridge motor driver, and dual VND7E040AJ high-side drivers - enabling rapid ECU prototyping for DC motor control and display-integrated automotive applications.

For engineers reviewing the AEK-MCU-C4MINI1 datasheet, AEK-MCU-C4MINI1 pinout, AEK-MCU-C4MINI1 application, or AEK-MCU-C4MINI1 equivalent, this board delivers validated hardware for functional safety–ready automotive development, including OpenOCD-based JTAG debugging, reverse-battery protection, dual 5 V/3.3 V power rails (2.75 A max), and standardized connectors for GPIO, ADC, SPI, I²C, UART, and LCD expansion via AEK-LCD-DT028V1.

Technical Context

The board implements a full automotive subsystem architecture: the SPC58EC80E5 MCU hosts two independent 180 MHz e200z4d cores with hardware cryptographic acceleration (HSM), supported by L5963 dual DC-DC converters delivering regulated 5 V and 3.3 V supplies (2.75 A total), plus dedicated 3.3 V ADC reference derived from its internal LDO.

Motor control is enabled through the VNH7040AY H-bridge (with short-to-battery/ground and open-load diagnostics) and two VND7E040AJ high-side drivers, while timing-critical functions leverage two eMIOS subsystems-each offering up to 32 timed I/O channels, configurable trigger outputs for ADC synchronization, and motor-control waveform generation capabilities.

FAQ

Does AEK-MCU-C4MINI1 support ISO 26262 ASIL-B development?

Yes. The board integrates the SPC58EC80E5 MCU - certified for ASIL-B per ISO 26262 - and includes hardware safety features such as dual-core lockstep monitoring (configurable), memory ECC, watchdog supervision, and diagnostic-capable motor drivers (VNH7040AY/VND7E040AJ), all documented in ST's SPC58EC safety manual and AutoDevKit safety guide.

Can both LCD connectors (top and bottom) be used simultaneously?

No. The top and bottom LCD connectors are electrically identical but mutually exclusive; only one may be populated at a time. The top connector is intended for debug-phase signal probing and data exchange, while the bottom connector minimizes stack height for deployment-ready configurations - as specified in DB5259 Rev 1, page 4.

What is the maximum current capability of the external 5 V/3.3 V power rail?

The L5963-based external power stage delivers up to 2.75 A total across both 5 V and 3.3 V outputs - shared dynamically per load demand. Each rail is independently rated: 5 V @ ≤2.75 A, 3.3 V @ ≤2.75 A, with thermal foldback and overcurrent protection active per ST's L5963 datasheet (Rev 7, Section 7.4).

Is OpenOCD debugging supported out-of-the-box?

Yes. The board embeds an FT2232H-based USB-JTAG interface preconfigured for OpenOCD, with standard SWD/JTAG pins routed to the MCU and virtual COM port exposed via USB. STSW-AUTODEVKIT software includes ready-to-use OpenOCD scripts and GDB launch configurations for SPC58EC80E5 core debugging and flash programming.
