1 / 2 page  Consumer and Industrial/General Embedded Market i.MX233 Applications Processor 32-bit Embedded Microprocessor – ARM® Overview The i.MX233 applications processor extends Freescale’s ARM9 portfolio and introduces several unique features such as power management, analog audio, 12-bit ADC’s and a touch screen controller that allows customers to eliminate external components, reducing their overall system bill of materials cost. 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, analog 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. The i.MX233 is offered in two packages to provide more tailored options for the various target applications. The 169 BGA package provides access to all of the features of the i.MX233. The 128 LQFP package provides a subset of these features in order to fit into the smaller pin count package. This smaller package option is ideal for cost-sensitive entry level applications that use small displays, don't require touchscreen user interface and have manufacturing restrictions (number of board layers). The feature differences are shown in the block diagram and table.

For plugged in “always on” devices, the low power consumption of the i.MX233 can improve energy efficiency. Simplified Development The integration of mixed-signal analog such as power management, analog audio and A/D channels reduces system complexity and speeds time-to-market. In addition, an imageprocessingunitsupporting24-bitVGA displays is integrated to provide rich user interfaces.Withawiderangeofconnectivity options,suchasUART,SDIO,USBandI2C, the i.MX233 processor provides the ability to connect wirelessly to other devices, through the use of off-chip Bluetooth™,Wi-Fiandother wireless protocols. |
