This slide shows the details of the RM48. From a communications point of view, the 10/100 Ethernet and USB host and device have been added to this family. It has three CAN interfaces and five SPIs. Three of the SPIs are multi-buffered and are two standard. These devices also have two UARTs and one I²C. As far as IO there are two high end timer co-processors inside these devices. The co-processors have their own CPU that executes their own instruction set. Texas Instruments provides a High End Timer Integrated Development Environment which is software that runs on the designer’s PC. This will help the designer get started with the High End Timer easily and quickly. The main system DMA transfers data in and out of the High End Timer, there is a secondary DMA that is used to avoid tying up the CPU. The RM48 has dual 12-bit multi-buffered analog to digital converters for a total of 24 channels. Finally, there is 16 dedicated general purpose IO pins in the RM48 which are capable of generating interrupts to the CPU from an outside source.
