CML24BT cpuModules
RTD's CML24BT cpuModule represents the latest in low power PCI Express embedded controllers. Based on an
Intel Atom® E3800 Series processor and chipset, the CML24BT 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 CML24BT is also available in a rugged and
fanless IDAN enclosure.
