The AT-VME-PADC-MPC8548 is the next generation of PowerPC based Single Board Computers in the AT series of products featuring Freescale’s MPC8548E PowerQUICC III processor which integrates the enhanced e500 PowerPC core and advanced features such as DDR2 SDRAM with 1GB, 128 MB of NOR flash, 1GB of NAND Flash, 64KB Serial EEPROM, up to 1 GHz of clock speed, 1MB of NVRAM. The system provides the required interfaces to interface custom modules in the system. The system provides communication bus interfaces like asynchronous communication ports on RS232/422 and two gigabit Ethernet ports. The SBC also features a watchdog timer, Real Time Clock and comes equipped with a single PMC mezzanine site.

The card has on-board Analog-to-Digital conversion channels and Digital-to-Analog Channels, providing additional resources for high-speed data acquisition applications. The above said feature is used in the Radar (IFF) Processing that is yet another functionality provided on-board. Radar signals are processed using mode generation, reply video processing and processed video generation. A communication link to control unit & SPU simulation is provided. Online diagnostics present detects presence/absence of external pry trig, ACP, nm, mode pulses & AA for decoder functions. Power on self test (post) & Plot processing are some of the additional features present. RADAR signals processing features include azimuth count pulse processing, primary trigger signal conditioning, processes in simulator, processes in RVP Mode ‘S’.

The SBC is available in Air-cooled and Conduction cooled temperature versions to suit various applications. Contact sales for more information.
