SLC-ARMADA • System on Module

ARM® Based Mezzanine Subsystem for Ethernet Switch Boards
AVB Protocol Support & Switch Management

As a System on Module, EKF introduces the SLC-ARMADA, a dual core 1GHz industrial microcomputer for networking applications, equipped with a low power Marvell® ARMADA® 3700 SoC (ARM® v8 Cortex™-A53).

The SLC-ARMADA was designed to support EKF Ethernet switch boards equipped e.g. with a Marvell® 88E6390 (industrial) or 88Q5072 (automotive) switching device. The SLC-ARMADA enables protocol support such as AVB/TSN and can be used for management and custom specific applications.

The SLC-ARMADA is provided with a high speed mezzanine connector, and communicates with the carrier card Ethernet switch via its 2.5GbE SerDes port and SMI/MDIO master interface.

The mezzanine module is equipped with up to 64GB e•MMC flash, 1GB DDR4 RAM and up to 64Mb SPI flash. In addition, the SLC-ARMADA offers popular I/O via the mezzanine connector such as USB3, PCIe® and UART, which makes the SoM interesting for universal industrial usage.
