2 CMA24BT cpuModule BDM-610000087 Rev A
CMA24BT cpuModules
RTD's CMA24BT cpuModule represents the latest in low power PCI Express embedded controllers. Based
on an Intel Atom® E3800 Series processor and chipset, the CMA24BT is offered with either a low power
1.46 Ghz Single-Core processor, a 1.33GHz Dual-Core processor, or a 1.91 GHz Quad-Core proccessor.
The DDR3 memory interface on the single- and dual-core models operate up to 1066 MT/s (533 MHz)
while the quad-core is 1333- MT/s (666 MHz). All memory chips are soldered directly onto the board.
The video interface of the cpuModule’s Intel Atom’s processor supports dual analog SVGA and
DisplayPort outputs. The two video outputs are independent, and can display separate images and display
timings, with audio support on the DisplayPort. Maximum resolution of both video outputs is 1920 x 1200.
A Serial-ATA (SATA) controller provides links to one disk drive on the PCIe bus connector as well as an
onboard solid-state disk drive which issoldered to the board for maximum reliability. Network connectivity
is provided by one integrated 10/100/1000 Mbps Ethernet controller. High-speed peripheral connections
include USB 2.0, with up to 480 Mb/sec data throughput. One additional SATA link and four USB 2.0
connections permit further expandability on the top and bottom-side PCIe/104 Type 2 connectors. The
bottom PCIe/104 connector also has four x1 PCI Express Gen 2.0 links. Other features include
RS-232/422/485 COM ports and Advanced Digital I/O (aDIO).
RTD has gone the extra mile to include additional advanced features for maximum flexibility. These include
an onboard surface-mount flash drive with a standard SATA interface. An Advanced Watchdog Timer is
provided that can generate an interrupt or reset when the timer expires. The CMA24BT is also available in
a rugged and fanless IDAN enclosure.
