The i.MX233 series Applications Processor extends Freescale"s ARM9 portfolio and introduces several unique features such as power management, analogue audio, 12-bit ADC"s and a touch screen controller that allows customers to eliminate external components. The i.MX233 integrates industry-leading power management technology to manage the power sequencing required by the processor itself and supplies power to other components in the system, such as external memories, from a single Li-Ion battery. Additionally, analogue audio features such as the stereo ADC/DAC and amplifiers, plus a mono speaker amplifier provide a complete solution in a single device for multimedia applications. Furthermore, many consumer applications require a rich graphical user interface which is supported with the LCD touch screen controller and basic hardware graphics acceleration with the pixel pipeline processor.
