Introduction
The MityDSP-L138, MitySOM-1808, MitySOM-1810 and MityDSP-6748 modules are System On Modules (SOMs)
designed to be easy to integrate into an end-user embedded system. The modules integrate many crucial
elements of an embedded system, and do so with an established design framework utilizing a common set of
core libraries. End-user design of the application PCB is also intended to be as simple as possible, allowing the
PCB designer to concentrate on the custom I/O interfaces – especially analog & mixed-signal – instead of getting
distracted with the learning curve of designing a brand new embedded digital system from scratch.
1.3
MityDSP-L138 Family Modules
The MityDSP-L138, MitySOM-1808, and MityDSP-6748 family of modules represents a 3
rd
generation SOM in the
MityDSP product line. These modules are based on a Texas Instruments OMAP-L138, Sitara-1808, Sitara-1810
and the TMS320C6748 System On Chip (SOC) modules, respectively. Each of these SOC modules are pin
compatible devices that employ one or both of an ARM 9 core and a DSP 674x floating point DSP core according
to the table below.
