1 Functional Description
1.1 General
The Cool FrontRunner is an all-in-one CPU module conforming to the PC/104-Plus specification. It comes up with 10/100BaseT Ethernet, AC97 sound on-board and an ATA-5 (Ultra DMA-66) compliant EIDE interface where an additional Compact Flash adapter can be mounted. The system’s main memory is soldered down on the board, providing 128 or 256MB DDR SDRAM.
Other features are a DiskOnChip Socket, PS/2 Mouse and Keyboard, four USB 1.1 compliant ports, three serial and one parallel port.
The AMD Geode [email protected] processor is the core of the board, featuring a high performance 2D graphics controller as well as an integrated display controller with improved unified memory architecture. CRT Displays with resolutions up to 1600 x 1200 x 16bpp at 85 Hz can be handled.
TFT-Panels can be handled via 24 Bit LVDS or 18 Bit parallel TFT interfaces with a maximum resolution of 1280 x 1024 pixels. The 64 Bit wide memory controller is integrated in the CPU providing low latency and an operating frequency of 111 MHz, 222 MT/S for DDR (Double Data
Rate).
The AMD CS5535 companion device provides the infrastructure of the board.
The CS5535 incorporates many I/O functions, including those found in typical Super-I/O chips. The device contains state-of-the-art power management that enables systems, especially battery powered systems, to significantly reduce power consumption.
An IrDA interface, hardware monitoring features and eight freely usable GPIO round up the widely spread application fields for the Cool FrontRunner.
