MEN Mikro A23C - 6U VMEbus Board with TI Sitara ARM Cortex-A15 CPU

Up to 2 GB DDR3 RAM, 2 PMC/XMC Slots, 2 Gigabit Ethernet

Introduction

The single-board computer A23C features a versatile high-performance, small footprint and low-power ARM processor, which allows application partitioning thanks to its 32-bit A15 CPU with integrated M4, GPU and DSP coprocessors. The A23C supports a reduction of system size, a reliable long-term operation without forced air cooling, and manifold computing functions with just one computer board.

Versatile Front I/O and Mass Storage

With one USB port, two Gigabit Ethernet ports and one RS232 COM at the front, the board offers the crucial basics of a multi-purpose industrial computer. As these interfaces are already provided by the ARM CPU, the remaining board space can be flexibly used for two PMC/ XMC modules. Being equipped with DDR3 SDRAM, Flash and FRAM, the need for flexible mass storage extensions is covered by slots for microSD card and mSATA.

Additional Interfaces via PMC/XMC

In addition, the A23C can be equipped with up to two XMC or PMC mezzanine cards on shared sites, providing both front I/O (XMC/PMC) and rear I/O (PMC) for functions such as graphics, mass storage, or further Ethernet. The two PMC slots support modules up to 64-bit/133-MHz PCI-X, while the XMC slots are controlled by one PCI Express x1 link. The modular extension with I/O mezzanines on a single board computer allows configured tailored systems from open standard components, reducing thus integration time and cost.

Designed for Harsh Environments

The A23C supports operation in a -40°C to +85°C temperature range. The board withstands shock and vibration as all components on the board are soldered, which is a prerequisite for reliable operation and a longer product lifetime.

Software Support

The CPU board is supported by the Universal Boot Loader (U-Boot), which can be used for bootstrapping operating systems, for hardware testing, or for debugging applications without running any operating system. TI Sitara processors guarantee long-term availability and compatibility with the latest versions of Linux or QNX.

Demanding Markets

The A23C is a computer board well suited for critical embedded applications, especially in the industrial automation and power & energy markets, for example as the central safety platform for power plants. With a guaranteed standard lifetime of ten years from product start, the A23C facilitates life-cycle management by making the overall system available at least for this period of time.
