The IC provides for three highly efficient DC/DC step-down converters, two DC/DC step-up converters, three RF LDOs, four digital LDOs, a low noise charge pump and a highly flexible backlight driver supporting a wide range of display sizes.

AS3658 at the same time offers high performance audio functions with a 18 bit audio DAC, a 16 bit audio ADC, a 5 band equaliser as well as headphone amplifiers, line-outputs, line-inputs, microphone inputs, audio mixer and several analog and digital audio interfaces. The unique ground noise cancellation feature delivers excellent sound quality in in-car environments. Moreover, a real time clock, 10 bit general purpose ADC and a 10 bit touch screen interface are integrated to complete the extensive feature set of AS3658. Due to customisable PROM programmable startup sequences the IC matches a wide variety of application processors.
