Introduction
Freescale’s i.MX family of microprocessors has
demonstrated leadership in the portable handheld
market. Building on the success of the MX (Media
Extensions) series, the i.MX21S (MC9328MX21S)
provides a leap in performance with an ARM926EJ-S
microprocessor core that provides accelerated Java
support in addition to highly integrated system functions.
The i.MX21S device addresses the needs of multiple
markets with intelligent integrated peripherals, advanced
ARM processor core, and power management
capabilities.
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
