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 media-

independent 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.
