MEN Mikro G40A - 3U compactPCI Serial ARM Cortex A72 SBC

Up to 8 GB DDR4 ECC DRAM Soldered, -40 to +85°C Operation


The G40A is a high-performance 3U CompactPCI Serial multicore CPU platform equipped with the NXP ARM Cortex A72 LS1046A processor. Featuring ARM core technologies and NXP data processing accelerators and I/O interfaces, G40A secures your application for the future by being full-virtualization ready - memory and I/O sub-systems can be virtualized - and available for 15 years from product introduction.

Wide Range of I/O, Network Connectivity

The G40A provides modern serial interface technologies such as PCI Express generation 3.0 (up to 8 Gbit/s), USB 3.0, SATA generation 3 (up to 6 Gbit/s). It is network connection ready by providing front Ethernet interfaces and an Ethernet switch. Nevertheless, compatibility with legacy interfaces is ensured with communications interfaces such as UART, I2C, SPI, etc.

Board Supervision and Management

The G40A is monitored using an MEN proprietary board management controller (BMC) which controls parameters such as voltages, temperature and provides a user configurable watchdog, making it ready for applications where functional safety is required. It supports low-power mode to enable Wake-on-LAN when the board's power supply is off.

Extensive Memory

The memory configuration of the G40A includes a fast DDR4 DRAM with ECC soldered to the board to guarantee optimum shock and vibration resistance. A non-volatile SRAM, an eMMC NAND Flash device and a microSD card can also be assembled offering space for user applications or usable as a local boot medium.

Perfect for Harsh Environments

With small 3U dimensions, G40A is perfectly suited for use in harsh environments, making it an ideal solution where space is limited but high processing capabilities are needed, e.g. in data collection applications on board trains. The board can be ordered in a version which enables fanless operation. The G40A comes with a tailored heat sink. All components are soldered for protection against shock and vibration according to applicable railway standards. The G40A is also coated so that it can be used in humid and dusty environments.
