Freescale Semiconductor extends ARM9 portfolio introducing the IMX233 processor which integrate more features such as : power management, analog audio, 12-bit ADC’s and a touch screen controller that allows customers to eliminate external components.
The i.MX233 can manage the power 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 like : Portable Media Players , Portable Navigation Devices , eBooks , Digital Picture Frames , audio peripherals and accessories , VoIP Handsets and other .
Freescale i.MX233 processor main features are : runs up to 454MHz , 16KB I & D L1 Cache , Integrated DC-DC converter with multiple channel outputs , Supports Li-Ion batteries , Direct power from 5V source , Battery charging capability , On-chip silicon speed and temp sensors , High-Speed USB Host / Device with Integrated PHY , UART , Serial peripheral interfaces (SPI) , 12-bit Low-Resolution ADC , Display controller optimized for up to 24-bit-per-pixel VGA (640 x 480) resolution , Pixel processing pipeline (PXP) , TV Encoder and 10-bit Video DAC out , Internal 32KB RAM , Support for external DDR1, Support for external NAND with hardware error correction (20-bit BCH or 8-bit Reed Solomon) , Stereo analog audio ADC/DAC , Stereo headphone amplifier , 1.5W mono speaker amplifier output , S/PDIF digital output , Serial Audio Interface (I2S) .
To design a application using the i.MX233 Freescale processor you can use the evaluation kit from the Freescale Semiconductor .
The evaluation Kit of the i.MX233 includes support for Linux®, DDR1, NAND, SDIO and USB and an optional display module using a 4.3” WQVGA TFT LCD is also offered.
