OMAP-L138, Sitara AM1808, C6748 MityDSP / MityARM Family Overview

The OMAP-L138 family of MityDSP System on Modules (SoM) includes the MityDSP-L138F, MityARM-1808F, and the MityDSP-6748F. These modules feature the latest technology from Texas Instruments' OMAP, Sitara, and C6000 families of single and multi-core processors tightly integrated with the new Spartan-6 FPGA from Xilinx.  This architecture provides system designers with the flexibility to address a wide range of system requirements. Given that all modules in the family are pin-for-pin compatible, and that each is available with and without the on-board FPGA, this family readily handles evolving product requirements, or those of a family of products requiring various levels of processing capability.




The table below gives a summary of the modules available:

 Module  DSP  ARM  FPGA
 MityDSP-L138  450 MHz  450 MHz  None
 MityDSP-L138F  450 MHz  450 MHz  Spartan-6
 MityARM-1808  None  456 MHz  None
 MityARM-1808F  None  456 MHz  Spartan-6
 MityDSP-6748  450 MHz  None  None
 MityDSP-6748F  450 MHz  None  Spartan-6


A rich set of interfaces are supported on each module, these interfaces include:

Standard Interfaces
 10/100 EMAC  SATA  eHRPWM
 USB (2)  McASP  Timers
 UART (3)  McBSP (2)  uPP
 MMC/SD (2)
 SPI (2)  uHPI
 LCD  I2C (2)  
 VPIF  eCAP  

Note: Interfaces in the OMAP-L138, AM1808, and C6748 share I/O pins, contact Critical Link for information on whether your specific set of interfaces are effected by on-chip pin muxing.


In addition to these integrated interfaces, the on-board FPGA allows for additional standard and custom interfaces to be added to the module's capabilities. Using Critical Link's libarary of available FPGA I/O cores, designers can easily add a variety of additional interface support to their designs, or design their own custom interface or logic to offload the CPU subsystem.
