Analog Integrated Microcontrollers
The AS352x series is an ultra low-power microcontroller based on the ARM9 32bit processor with fully integrated high performance audio features and system power management in a single package for optimized system costs. Thanks to the big 320kB internal RAM, many applications do not require an additional external RAM - which further saves system costs.
