STMicroelectronics AEK-MCU-C1MLIT1

Overview

AEK-MCU-C1MLIT1 from STMicroelectronics is an automotive-grade MCU discovery board built around the SPC582B60E1 32-bit Power Architecture® microcontroller (80 MHz, 1 MB Flash, eQFP64), featuring on-board USB-JTAG PLS debugger, full I/O access via extension headers, 40 MHz crystal, and three user LEDs - designed for rapid evaluation of Chorus-family body control and gateway applications.

For engineers reviewing the AEK-MCU-C1MLIT1 datasheet, AEK-MCU-C1MLIT1 pinout, AEK-MCU-C1MLIT1 application, or AEK-MCU-C1MLIT1 equivalent, this board delivers ready-to-run firmware via SPC5-STUDIO with AutoDevKit plug-in, supports JTAG/SWD debugging, provides Arduino-compatible headers, and enables direct validation of LINFlexD, DSPI, CAN, and I²C peripheral integration in automotive ECUs.

Technical Context

The board implements the SPC582B60E1 in eQFP64 package with dedicated power domains (VDD_HV_IO_MAIN, VDD_HV_FLA, VDD_LV), isolated clocking (40 MHz XTAL + internal PLL), and hardware reset supervision via STM6315RDW13F. All 64 MCU pins are routed to dual-row 0.1" headers (CN1–CN10) with configurable pull-ups/downs and signal conditioning (e.g., SN74LVC2T45 level translators for USB interface).

It integrates three independent debug paths: embedded PLS UDE-compatible USB-JTAG (FTDI2232-based), optional external JTAG connector (JP5), and SWD via mini-B USB port - enabling simultaneous firmware load, real-time trace, and boundary-scan verification without external tools.

FAQ

Does AEK-MCU-C1MLIT1 support CAN FD?

No. The SPC582B60E1 MCU on this board integrates only classical CAN 2.0B controllers (CAN0–CAN3), each supporting up to 1 Mbps data rate and 11-bit identifiers. CAN FD capability requires SPC584B or later Chorus derivatives not present on this revision.

Can I use SPC5-STUDIO without installing PLS UDE?

Yes. SPC5-STUDIO includes its own integrated debugger (SPC5-UDE Lite) compatible with the on-board FTDI2232 JTAG interface. PLS UDE is optional and only required for advanced trace analysis, multicore debugging, or third-party toolchain integration.

What is the maximum operating temperature rating?

The board is rated for −40 °C to +105 °C ambient operation, matching the SPC582B60E1's AEC-Q100 Grade 2 qualification and conformal coating-ready PCB layout with automotive-grade passives (e.g., 105 °C X7R ceramics, 105 °C electrolytics).

Are the Arduino headers electrically compatible with 5 V logic?

No. The Arduino-compatible headers (CN6, CN8) are connected directly to MCU I/O pins operating at 3.3 V LVCMOS levels. Applying 5 V signals may damage the SPC582B60E1. Level translation (e.g., SN74LVC2T45) is implemented only on USB interface lines, not on Arduino headers.
