The module includes FLASH (NAND, and NOR) and mDDR2 RAM memory subsystems. The MityDSP-L138 provides a complete and flexible digital processing infrastructure necessary for the most demanding embedded applications development. The onboard OMAP-L138 processor provides a dual CPU core topology. The OMAP- L138 includes an ARM926EJ-S micro-processor unit (MPU) capable of running the rich 1 Copyright 2013, Critical Link LLC Specifications Subject to Change 60-000038-1B Critical Link, LLC MityDSP-L138 System on Module www.CriticalLink.com 21-OCT-2020 software applications programmer interfaces (APIs) expected by modern system designers. The ARM architecture supports several operating systems, including linux and windows XP embedded. In addition to the ARM core, the OMAP-L138 also includes a TMS320C674x floating point digital signal processing (DSP) core. The DSP core supports the freely provided TI DSP/BIOS real-time kernel. Users can leverage the DSP to execute real-time compute algorithms (codecs, image/data processing, compression techniques, filtering, etc.) 1.2V Up To 16MB NOR Up To 256MB Flash 1.8V mDDR Memory Power (SPI interface) 16-bit wide Management For uBoot bootloader 3.3V System JTAG Clocks Header JTAG/Emulator Texas Instruments OMAP-L138 456-MHz ARM926EJ-S RISC MPU 456-MHz C674x VLIW DSP (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 MityDSP-L138 Block Diagram Figure 1 provides a top level block diagram of the MityDSP-L138 processor card. As shown in the figure, the primary interface to the MityDSP-L138 is through a standard SO-DIMM-200 card edge interface. The interface provides power, synchronous serial connectivity, and many other interfaces provided by the OMAP processor. Details of the SO-DIMM-200 connector interface are included in the SO-DIMM-200 Interface Description, below. 2 Copyright 2013, Critical Link LLC Specifications Subject to Change 60-000038-1B 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
