Features
• 2x 10BASE-T1S ports:
– 1x port with PHY-MAC transceiver converting from 10BASE-T1S to SPI
– 1x port with PHY transceiver converting from 10BASE-T1S to mediaindependent interface (MII)
• The two transceivers are connected with the main board SPC58EC80E5 MCU
• The MCU firmware supports both transceivers at the same time allowing them to work in parallel
• For the transceiver with PHY, we implement a dedicated Ethernet MAC inside the MCU firmware
• The MCU firmware runs under FreeRTOS™ implementation on SPC58EC80E5
• 10BASE-T1S according to standard protocol:
– Point-to-point direct connection or multidrop topology with up-to-eight nodes
– Up to 10 Mbit/s data is transferred over a single pair of wires
– Physical layer collision avoidance (PLCA)
– Carrier sense multiple access/Collision detection (CSMA/CD) media access control
• SPSB0813 automotive power management IC (PMIC) with CAN-FD transceiver
• JTAG integrated programmer and debugger
• 5 CAN-FD transceivers (including the one integrated in the SPSB0813 PMIC)
• 1 connector for I2C/UART serial communication
• Wake up and reset buttons
• 2 general-purpose connectors (8 pins each)
• 2 SPI ports
• One plug connector to plug in an eventual daughter board, a power distribution unit (PDU)
• Reverse battery-protection dedicated circuit
• L5963 integrated DC-DC converter for potential system supply
• Compact size: 110 mm x 100 mm
• Included in the AutoDevKit ecosystem

Description
The AEK-COM-10BASET evaluation board is a powerful tool to explore various vehicle network architectures, leveraging on the new 10BASE-T1S automotive Ethernet protocol implementation and other on-board legacy automotive interfaces (CAN, CAN-FD and SPI).
This board merges the innovations brought by the new 10BASE-T1S specification with the high-performance dual-core SPC58EC80E5 chorus family microcontroller.
The AEK-COM-10BASET perfectly meets the requirements of new megatrends in the automotive industry, such as personalization, electrification, autonomy, and full connectivity, which are moving in-vehicle networks away from domain-based solutions, gravitating towards new zonal architectures.
