The MCIMX283DVM4B is a low-power high-performance Application Processor optimized for the general embedded industrial and consumer markets. 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-DC switching converter and multiple linear regulators. These 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.
