4.1.3 Layer Stack-Up

Choosing the number of board layers and the layer stack-up is dependent on the number of connections that need to be made on the PCB along with the cost of producing the PCB. A 4-layer board or more is often the best choice for C2000 devices. This enables the designer to include a clean ground plane and split power plane. In terms of configuration, two diagrams showcasing common 4-layer and 6-layer board stack-ups are shown. The 4-layer board stack-up consists of a signal/component layer, ground plane, split power plane (3.3 V, 1.2 V, and so forth), and signal/component layer. For the 6-layer board, the stack-up is as follows: signal/component layer, ground plane, split power plane (3.3 V, 1.2 V, and so forth), signal layer, another ground plane, and signal/component layer.
