The MitySOM-1808 provides a complete and flexible CPU infrastructure necessary for the most demanding embedded applications development. The AM1808 includes an ARM926EJ-S micro-processor unit (MPU) capable of running the rich software applications programming interfaces (APIs) expected by modern system designers. The ARM architecture supports several operating systems, including Linux, QNX and Windows XP embedded. Linux drivers are available for all interfaces. 1 Copyright 2013, Critical Link LLC Specifications Subject to Change Critical Link, LLC MitySOM www.criticallink.com MitySOM-1808 Processor Card 5-MAR-2014 1.2V 8MB NOR Flash Up To 256MB 1.8V (SPI interface) mDDR Memory Power For uBoot 16-bit wide Management bootloader 3.3V System JTAG Clocks Header JTAG/Emulator Texas Instruments AM1808 456-MHz ARM926EJ-S RISC MPU (Many pins are multiplexed between peripherals) Boot Up To 512MB Config NAND Flash 8-bit wide For root FFS SO-DIMM-200 (DDR2 Connector) Figure 1 MitySOM-1808 Block Diagram Figure 1 provides a top level block diagram of the MitySOM-1808 processor card. As shown in the figure, the primary interface to the MitySOM-1808 is through a standard SO-DIMM-200 card edge interface. The interface provides power, synchronous serial connectivity, and a rich set of interfaces available for application defined interfacing. Details of the SO-DIMM-200 connector interface are included in the SO-DIMM-200 Interface Description, below. AM1808 mDDR2 Memory Interface The AM1808 includes a dedicated DDR2 SDRAM memory interface. The MitySOM- 1808 includes up to 256 MB of mDDR2 RAM integrated with the AM1808 processor. The bus interface is capable of burst transfer rates of 600 MB / second. Note that the OSCIN frequency to the AM1808 processor on the module is 24MHz. AM1808 SPI NOR FLASH Interface The MitySOM-1808 includes 8 MB of SPI NOR FLASH. This FLASH memory is intended to store a factory provided bootloader, and typically a compressed image of a Linux kernel for the ARM core processor. 2 Copyright 2013, Critical Link LLC Specifications Subject to Change EMAC MII/MDIO MMCSD 0 UART 0,1,2 McBSP 0,1 SPI 0,1 I2C 0,1 McASP eCAP eHRPWM Timers SATA USB 0,1 Resets & RTC LCD uPP UHPI EMAC RMII MMCSD 1 VPIF I/O Boot Config EMIFA (16-bit) 3.3 V GND
