2 CMX34GS cpuModule BDM-610000082 Rev A
CMX34GS cpuModules
RTD's CMX34GS cpuModule represents the latest in low power PCI Express embedded controllers. Based on an
AMD Fusion G-Series APU processor and chipset, the CMX34GS is offered with either a low power 615 MHz
Single-Core processor or a high performance 1.0 GHz Dual-Core processor that supports a 1.33 GHz frequency
on one core, complete with a DDR3 memory interface operating at up to 800 MT/s (400 MHz). All memory chips
are soldered directly onto the board.
The video interface of the cpuModule’s G-Series APU processor is an internal AMD Radeon HD 6250 (615 MHz
single core option) running up to 276 MHz or the HD 6290 (1 GHz dual core option) which runs up to 400 MHz.
Both options provide dual analog SVGAand 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 a fast 3.0 Gbit/sec connection to the hard drives. Network connectivity
is provided by two integrated 10/100/1000 Mbps Ethernet controllers. High-speed peripheral connections
include USB 2.0, with up to 480 Mb/sec data throughput. Four additional SATA links and USB 2.0 connections
permit further expandability on the top and bottom-side PCIe/104 Type 2 connectors, along with x1 PCI Express
Gen 2.0 links. Other features include two 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 SATA 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 CMX34GS is also available in a
rugged, fanless IDAN enclosure.
