The MitySOM-1810 provides a complete and flexible CPU infrastructure necessary for the most demanding embedded applications development. The AM1810 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, including the PROFIBUS interface. 1 Copyright 2013, Critical Link LLC Specifications Subject to Change Critical Link, LLC MitySOM www.criticallink.com MitySOM-1810 Processor Card 5-MAR-2014 1.2V 8MB NOR Flash Up To 256MB 1.8V (SPI interface) mDDR Memory Power For uBoot 2.5V 16-bit wide Management bootloader 3.3V System JTAG Clocks Header JTAG/Emulator Texas Instruments AM1810 375-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-1810 Block Diagram Figure 1 provides a top level block diagram of the MitySOM-1810 processor card. As shown in the figure, the primary interface to the MitySOM-1810 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. PROFIBUS Interface Texas Instruments Inc. (TI) has integrated PROFIBUS functionality into its AM1810 Sitara ARM microprocessor (MPU). The solution utilizes one of the onboard UARTS and connects directly to the RS-485 transceiver and therefore eliminates the need of an external PROFIBUS ASIC or FPGA. Customers using the MitySOM-1810 in their industrial application can save cost and reduce design complexity as well as PCB space. Furthermore, the industrial application benets from the low-power architecture of the Sitara ARM MPU and the MitySOM-1810 platform from TI and Critical Link. The AM1810 Sitara ARM MPU PROFIBUS Slave solution has been certified by PROFIBUS International (PI). The PROFIBUS real-time frame handler (Fieldbus Data Link or FDL) is encapsulated in the Programmable Real-Time Unit Subsystem (PRUSS), which is part of the AM1810 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
