The I.MX28 series low-power high-performance Applications Processor optimized for the general embedded industrial applications. The core of the i.MX28 is Freescale's fast, power-efficient implementation of the ARM926EJ-S? core, with speeds of up to 454MHz. The integrated power management unit (PMU) on the i.MX28 is composed of a triple output DC to DC switching converter and multiple linear regulators. This provide power sequencing for the device and its I/O peripherals such as memories and SD cards, as well as provide battery charging capability for Li-Ion batteries. The i.MX28 processor includes an additional 128kB on-chip SRAM to make the device ideal for eliminating external RAM in applications with small footprint RTOS. The i.MX28 supports connections to various types of external memories, such as mobile DDR, DDR2 and LV-DDR2, SLC and MLC NAND flash. It can be connected to a variety of external devices such as high-speed USB2.0 OTG, CAN, 10/100 Ethernet and SD/SDIO/MMC.
