Command Based Pattern Generator for Color LEDs (1.65V
≤ V
DDIO ≤ VDD1,2V) (unless otherwise
noted)
The LP3952 has an unique stand-alone command based pattern generator with 8 user controllable 16-bit
commands. Since registers are 8-bit long one command requires 2 write cycles. Each command has intensity
level for each LED, command execution time (CET) and transition time (TT) as seen in the following figures.
