7.1
The UCB1100 has nine power supply pins, since the UCB1100
contains five power supply regions within the circuit. The analogue
and digital parts have their separate power supplies to reduce the
interference between these parts. The speaker driver circuit is
powered separately (vdda2/vssa2) from the other analogue circuit
parts and the touch screen switch matrix has its own ground pin
(vssa3). This separation in the analogue part reduces the
interference between the speaker driver and the touch screen switch
matrix, which has relatively large and fluctuating current
consumption and the remaining parts of the analog.
Power Routing Strategy
The vssd pins and the vssa1 pin are connected within the UCB1100
circuit. It is recommended to connect the vssd pins and the vssa1
directly to a ground plane on the PCB. The split in power supply
connections should be maintained on the PCB to get optimal
separation. Figure 36 shows the recommended PCB power supply
strategy.
