MEN Mikro A15C - 6U VME64 MPC8245 CPU Board (PMC Modules)

Up to 2 GB (ECC) DRAM, 2 PMC Slots, 2 Gigabit/1 Fast Ethernet

Introduction

The A15C is a PowerPC® MPC8245 based single-board computer for embedded applications. It features full VME64 support and it can be used as a master or a slave in a VMEbus environment. The A15C provides 1 MB local dual-ported SRAM for slave access and communication between the local CPU and another VMEbus master.

The CPU card comes with the MPC8245 PowerPC® with 400 MHz clock frequency and local 32-bit/33-MHz PCI data bus. It is a complete state-of-the-art SBC offering DRAM, Flash and CompactFlash® memory, dual Fast Ethernet, four COMs, USB, IDE and keyboard/mouse interfaces as well as an optional onboard hard disk.

In addition, the A15C can be equipped with PMC mezzanine cards supporting both front I/O and rear I/O. PMCs may particularly be used for intelligent telecom I/O. The modular combination of I/O functionality on a single-board computer allows to build up tailored control systems which appear as customized solutions based on standard components.

Depending on the kind of I/O requirements, further standard versions of A15 are availabe for other mezzanine standards.

The A15 comes with MENMON support. This firmware/BIOS can be used for bootstrapping operating systems (from disk, Flash or network), for hardware testing, or for debugging applications without running any operating system.

The A15 single-board computer is partly compatible with the MVME2100 board by Motorola.
