Page 3: Introduction
MGS-EVM is a compact, cost-effective multi-gig secure evaluation board, ideal for automotive Ethernet use cases. Consisting of the SJA1110 switch along with TJA1121 and TJA1104 PHYs, the board demonstrates MACsec security on both PHYs and enables rapid prototyping with integrated software examples based on Real-Time Drivers (RTDs). -

UM12269 NXP Semiconductors SJA1110 multi-gig secure evaluation board 4.4 Board overview The main components and ports on the SJA1110-MGS-EVM are indicated and labelled in Figure 3. Jumpers and DIP switches are highlighted in Figure 4 and described in Table 1... - Page 7 In NVM boot mode, the SJA1110 firmware boots from the external Flash memory on the board. In SDL boot mode, the SJA1110 waits for a companion device to load the firmware via the SPI_HAP interface. SPI_HAP is a multiplexed SPI interface used to load firmware onto the device (SPI_HOST, via CS1) and for register-level access (SPI_AP, via CS0).

Page 13: Power Supply
SJA1110 multi-gig secure evaluation board 4.6 Power supply The power supply for the SJA1110-MGS-EVM is built around the VR5510 PMIC to exploit and demonstrate synergies with S32G projects. The board is powered by a single 12 V input. It is advised to use an adapter that can deliver at least 1 A of current. -
Page 14: Interfaces
Figure 10. SMI interface 4.7.2 SPI The SPI_PER interface on the SJA1110 is available on pin header J3, allowing another device to be connected to this interface. The SJA1110 be used as SPI leader to this device. A typical use-case would be a cascaded switch architecture with two switches, in which one switch loads the configuration to the seconds switch via SPI. -
