A test board was used to replicate a sleeping vehicle ECU which is referred to as Link Partner 2 (LP2). LP2 includes a LM62460-Q1 buck converter, LP8762-Q1 power management integrated circuit (PMIC), AM273x-Q1 ArmĀ® based MCU, and the DP83TC812-Q1 TC10-compliant automotive Ethernet PHY. LP2 was used in conjunction with the DP83TC812EVM-MC to establish a link between the two devices, enter sleep mode, and then perform a remote TC10 wake sequence. The DP83TC812EVM-MC is referred as Link Partner 1 (LP1). Figure 2-1 shows how these components behave as a system.
