In the consumer area, many semiconductor companies make MCU (Micro Controller Unit) using ARM core. Sanken electric is a bit different and they make MCU targeting the power supply related products. The new MCU, "MD6603", is 4th device of their MD series. Utilizing their knowledge and the technology of digital power devices and made the power control design much easier and higher performance. New product page can be found here. "MD6603 is a MCU (Micro Controller Unit) which includes an "EPU" core, in addition to the "8bit CPU + 16 bit Tiny DSP (x2) " which is incorporated in the conventional MD series. EPU is a 16 bit processor with zero latency task switching. A close interaction with rich analog functions inluding Tiny DSP and high resolution PWM enables real time processing of complex events with only a small delay. It also includes rich analog components and strong system support functions , which can assist you in creating a more efficient and high performing power control application. " The product page describes key features and specs. The block diagram is also shown in the page, it is really different from the MCU chips for the portable consumer products. The main processor is 8 bit 8051 for the small computation, however, the DSP can mange the signal processing side from analog signals, and it seems quite good enough for the task or scheduling oriented applications which is listed in the page. ・DC/DC power supply ・AC/DC power supply ・LED lighting control ・LED signage ・Motor control ・Chargers ...and so forth One of the key features that is new to their MD series is EPU that can handle the each event input.
The product page shows the block diagram and the descriptions. "*EPU (Event Proceccing Unit): A Multi Context Processor for arithmetic operations and conditional judgments with zero latency task switching triggered by internal event signals" Although I am not sure how it actually works yet, this feature would give additional real-time task processing to the applications. It seems like this device is still under development and datasheet is not available at this moment. I think this type of MCU would be a good combination with Arduino or Raspberry PI. It would be nice if we can get the part and build a shield boards for the quick experience.
