1 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.MX21 (MC9328MX21)
provides a leap in performance with an ARM926EJ-S™
microprocessor core that provides native security and
accelerated Java support in addition to highly integrated
system functions. The i.MX products specifically
address the needs of the smartphone and portable
product markets with their intelligent integrated
peripherals, advanced processor core, and power
management capabilities.
The i.MX21 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 a
video accelerator module, LCD controller, USB On-The-
Go, CMOS sensor interface, and two synchronous serial
interfaces offer designers a rich suite of peripherals that
can enhance any product seeking to provide a rich

Introduction
multimedia experience. In addition, the i.MX21 provides optional hardware enabled security features
including high assurance boot mode, unique processor IDs, secret key support, secure RAM, and a security
monitor. These optional features enable secure e-commerce, digital rights management (DRM),
information encryption, and secure software downloads.
For cost sensitive applications, the NAND Flash controller allows the use of low-cost NAND Flash
devices to be used as primary or secondary non-volatile storage. The on-chip error correction code (ECC)
and parity checking circuitry of the NAND Flash controller frees the CPU for other tasks. WLAN,
Bluetooth and expansion options are provided through PCMCIA/CF, USB, and MMC/SD host controllers.
The i.MX21 is packaged in a 289-pin MAPBGA.
