General Description     Measuring only 58mm by 45mm, the Mini8118 processor card is a small and low-cost controller board designed to the core processing component for your next embedded design. It is based on TI’s AM1808 ARM9 application processor which is powered by 375-MHz ARM926EJ-S RISC MPU core. The board has 128bytes mobile DDR2, 128Mbytes NAND Flash and 8Mbytes SPI Flash and uses two 2.0mm space 3*27-pin dip connectors to bring out many hardware peripheral signals and GPIOs from the CPU.

    To help with customers’ prototyping and evaluation, Embest has also designed an expansion board for the single board computer called SBC8118. The SBC8118 has exposed many additional hardware interfaces based on the Mini8118 including Serial ports, LCD/TSP, USB Host, Ethernet, RS485, SATA, Camera, SD card, JTAG, etc. It has one 14-pin JTAG interface which can be used with XDS100v2 emulator available from Embest. Embest also offers 4.3” and 7” LCD display with touch screen as optional modules for this board.

    The Mini8118 processor card is an industrial-grade module which can work in harsh environment. It is ideal for various applications like medical, industrial, communication, consumer electronics products and etc.


Two 2.0mm space 3*27-pin dip connectors
    Embest Mini8118 processor card is connected to carrier board via two 2.0mm pitch 3*27-pin DIP connectors.
