Product Descriptions

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 accelerated Java support in addition to highly integrated system functions. The i.MX21 device specifically addresses the needs of the smartphone and portable product markets with intelligent integrated peripherals, advanced processor core, and power management capabilities.

Thei.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-TheGo, 1-Wire® interface, CMOS sensor interface, and synchronous serial interfaces offer designers a rich suite of peripherals that can enhance many products seeking to provide a rich multimedia experience.

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 device is packaged in a 289-pin MAPBGA.
