The i.MX28 processor includes an additional 128-Kbyte 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.
The i.MX28 can be connected to a variety of external devices such as high-speed USB2.0 OTG, CAN,
10/100 Ethernet, and SD/SDIO/MMC.
