Microcontroller Module with SDRAM and NAND Flash

With this project, a paradigm shift was undertaken at the customer's site. In the past, microcontroller systems were placed directly on the PCB (no modularity). Since this new project required an almost unmanageable number of electronics with various functionalities, strategies had to be developed to reduce the development effort for the electronics (and firmware). For this purpose, CORESIGHT was able to work out a concept with the customer, in which a microcontroller SOM and a flexibly deployable motor controller were to be developed by CORESIGHT. The SOM and the motor controller could be used multiple times throughout the entire product, thus enormously reducing the development effort and keeping the maintenance for electronics and firmware within a manageable scope. The SOM design has been functioning extremely robustly since the first production run and only minor adjustments to the electronics were necessary for subsequent production runs. Tasks in the area of electronics:
