In advantech RISC SOM-A200 ultra low power series (SOM-A2552,

SOM-A2558 and SOM-A2558) all follow the same pin definition in X1,X2 and X3. So, users could design their own CSB to be compatible with all advantech RISC ultra low power series SOM easily. In this way, users’CSB will have powerful upgrade capability & option choice.

X1: AMI bus

AMI bus connector is PXA255 ARM bus. It includes complete system address lines, data lines, GPIOs (for interrupt source) and Chip select pins (nCS). Users could use this bus to extend any other IC controller on CSB to implement the function which SOM modules not provide. In order to keep the system bus signals well, every address lines and data lines are driven by buffers. Buffers’signals direction controls are implemented by CPLD.

X2: SODIMM-200 connector

Most I/O functions fog in X2. X2 includes PCMCIA/CF, T/S, Audio, system reset control, SOM system power input pins, I2C, USB host, USB client, RS-232 ports, RS-485 port, LCD out and PS/2 ports. Every I/O functions will be described in the following content in detail.

X3: Feature Extension connector

Advantech SOM-A200 series products use dual-chip or triple-chip design concepts. The companion chip’s I/O function will come out through the X3. In SOM-A2558 series, PCI, SD/MMC I/F is included in X3.
