The A15B is an advanced PowerPC® 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 A15B 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 on-board hard disk. A software-loadable FPGA is available for individual user-defined functions such as additional UARTs, a CAN bus interface, DSP functions etc.
In addition, the A15B can be equipped with M-Module™ mezzanine cards supporting both front I/O and rear I/O. M-Modules™ are recommended for real-world I/O like analog/binary process I/O and instrumentation 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.
