TheEF-22LF features the advanced and power-efficient ARM926EJ-S core operating at speeds 266 MHz and Smart Speed products

that offer high performance processing optimized for lowest power consumption. On-chip modules such as a video accelerator module,

LCD controller r( 640 x 480 ), USB 1.0, and synchronous serial interfaces offer designers a rich suite of peripherals that can enhance

many products seeking to provide a rich multimedia experience.

This targeted functionality enables the EF-22LF to address the needs of cost-sensitive applications such as HMI interface or small size

Photo customer display, information appliances, smart phones, Web browsers, audio players, handheld computers based on the popular

WinCE5.0 platform.
