Datasheet

Data Modul has introduced the conga-MA3, the new generation of Intel Atom processors in COM Express Mini Type 10 format from their Partner congatec. The conga-MA3 provides twice the performance over its predecessor plus an optimised product lifespan thanks to development with ceramic condensators.

The Type 10 module pinout is a refresh of Type 1 and uses the single 220 pin A-B connector. Type 10 COMs take advantage of modern display interfaces. The conga MA3 can support either TMDS (HDMI/DVI) or DisplayPort. In addition, it supports one LVDS channel. It comes in five different Intel Atom processor-based versions (formerly codenamed “Bay Trail”) for high scalability. It ranges from the entry-level single-core Intel Atom processor E3815 with 1.46 GHz and a low power consumption of 5 watts, up to the quad-core Intel Atom processor E3845 with 1.91 GHz and 10 watts.

The module provides up to 8 GByte of fast DDR3L onboard memory with options for onboard eMMC as well. The eMMC supports an integrated wear levelling feature for high data security. The improved graphics supports DirectX 11, OpenGL 3.2, OpenCL 1.2 and high-performance, flexible hardware to decode multiple high-resolution full HD videos in parallel.

Up to 2,560 x 1,600 pixels with DisplayPort and 1,920 x 1,200 pixels with HDMI are natively supported in the processor. It is possible to connect up to two independent display interfaces, including one via a 24-bit LVDS output. Thanks to native USB 3.0 support, the modules achieve fast data transmission with low power consumption.

A total of seven USB 2.0 ports are provided, and one USB 3.0 SuperSpeed port is supported. Four 5 Gb/s PCI Express 2.0 lanes and two SATA interfaces operating up to 3 Gb/s enable fast and flexible system extensions. The Intel Gigabit Ethernet Controller I210 helps with software compatibility. ACPI 5.0, I2C bus, LPC bus for easy integration of legacy I/O interfaces and Intel High Definition Audio complete the feature set.
