Introduction
THEMIS is a Single Board Computer, measuring just 102 x 146 mm (4,02
”
x 5,75
”
) based on embedded NXP i.MX 8 Family, featuring multicore processing (Single
or Dual ARM Cortex
®
-A72 cores + Quad ARM Cortex
®
-A53 cores + Dual general-purpose Cortex
®
-M4 processor).
Graphics features of the board are managed directly by NXP i.MX8 processor, which integrate 2x Graphics accelerators Vivante GC7000 / XVSX or GC7000 Lite /
XVSX (QuadMax and QuadPlus) GPUs, supporting OpenGL
®
ES 1.1 / 2.0 / 3.0 / 3.1, Open CL 1.2 OpenGL 3.x, DirectX 11. This family of processors integrate one
embedded VPU, which allows HW acceleration for video decoding of H.265 (4K30), H.264 (1080p60) and encoding of H.264 (1080p30).
The board is completed with up to 8GB LPDDR4 directly soldered on board, and one eMMC Flash Drive, directly accessible like any standard Drive, with up to 64GB
of capacity. Mass storage capabilities are completed by a microSD Card slot. External SSD modules can expand mass storage capabilities through M.2 Key B Slot
with S-ATA interface (factory option with PCIe x1 for plugging M.2 Modem modules)
The processor offers two RGMII interfaces which, through dedicated Ethernet Transceivers, allows the implementation of two Gigabit Ethernet interfaces.
The communication / networking capabilities of the board are completed by an M.2 Key B Slot, which allows plugging M.2 Modem modules with USB or PCI-e
interface, an M.2 Key E Slot, which allows plugging M.2 WiFi + BT modules with USB or PCI-e interface and by an optional WiFi a/b/g/n/ac + BT LE 4.2 combo
embedded module, with ceramic SMT antennas on-board.
The M.2 Key B Slot can rely on an on-board microSIM slot.
The THEMIS offers an USB 3.0 Standard Type-A connector (combo with RJ-45 GbE connector), one USB 2.0 standard Type-A connector (combo with RJ-45 GbE
connector), an internal USB 2.0 header and one USB 2.0 with OTG functionalities on micro-AB socket.
The audio functionalities of this board are realised by an I2S audio codec, which manages Line out and Mic In interfaces on a combo TRRS audio jack.
The standard functionalities of this board are then completed by 3x UART interfaces (RS-232, RS-485/RS-422, TTL level), an I2C interface, four A/D inputs, an SPI
interface, 6x GPIOs and three CAN Bus interfaces.
The board is available both in commercial and in industrial temperature range.
