The panels for industrial applications i.MX233 integrates industry-leading power Audio Key Features management technology to manage the power Stereo analog audio ADC/DAC sequencing required by the processor itself CPU Stereo headphone amplifier and supplies power to other components in ARM926EJ-S runs up to 454MHz the system, such as external memories, from 1.5W mono speaker amplifier output 16KB I & D L1 Cache a single Li-Ion battery. Additionally, analog S/PDIF digital output audio features such as the stereo ADC/DAC Serial Audio Interface (I2S) Power Management and amplifiers, plus a mono speaker amplifier Integrated DC-DC converter with multiple Benefits provide a complete solution in a single device channel outputs for multimedia applications. Furthermore, many CPU Performance and Low Power Supports Li-Ion batteries consumer applications require a rich graphical 454MHz ARM9 CPU with ample headroom Direct power from 5V source (USB, wall user interface which is supported with the LCD for many consumer and embedded power or other source) touch screen controller and basic hardware applications without sacrificing battery life. graphics acceleration with the pixel pipeline Battery charging capability For plugged in always on devices, the low processor. On-chip silicon speed and temp sensors power consumption of the i.MX233 can improve energy efficiency. The i.MX233 is offered in two packages to Connectivity provide more tailored options for the various High-Speed USB Host / Device with Simplified Development target applications. The 169 BGA package integrated PHY The integration of mixed-signal analog such provides access to all of the features of the UART as power management, analog audio and i.MX233. The 128 LQFP package provides A/D channels reduces system complexity Serial peripheral interfaces (SPI) a subset of these features in order to fit into and speeds time-to-market. In addition, an 12-bit Low-Resolution ADC (LRADC) the smaller pin count package. This smaller image processing unit supporting 24-bit VGA 3.3V general purpose I/O package option is ideal for cost-sensitive entry displays is integrated to provide rich user level applications that use small displays, don t Multimedia and Graphics Processing interfaces. With a wide range of connectivity require touchscreen user interface and have 2 options, such as UART, SDIO, USB and I C, Display controller optimized for up to manufacturing restrictions (number of board the i.MX233 processor provides the ability to 24-bit-per-pixel VGA (640 x 480) resolution layers). The feature differences are shown in the connect wirelessly to other devices, through Pixel processing pipeline (PXP) to handle block diagram and table. the use of off-chip Bluetooth , Wi-Fi and other post display frame pre-processing in wireless protocols.
