The i.MX21S features the advanced and power-efficient
ARM926EJ-S core operating at speeds up to 266 MHz
and is part of a growing family of Smart Speed products
that offer high performance processing optimized for
lowest power consumption. On-chip modules such as an
LCD controller, USB On-The-Go, 1-Wire^® interface,
and synchronous serial interfaces offer designers a rich
suite of peripherals that can enhance many products.
For cost sensitive applications, the NAND Flash
controller allows the use of low-cost NAND Flash
