The i.MX355 processor takes advantage of the Arm11™ core running at 532 MHz with the advantage of an Image Processing Unit. The i.MX355 integrates Enhanced Serial Audio Interface (or ESAI) for multi-channel (5.1) audio, SPDIF I/O for compressed digital audio connectivity and an advanced sample rate converter (ASRC) for mixing digital content with different sampling frequencies. For flexible connectivity options the i.MX355 integrates 2-CAN modules, Media Local Bus (or MLB), Ethernet and the ability to connect to external wireless modules via SDIO or USB ports. To reduce system costs a full-speed PHY on the Host port and high-speed PHY on the On-the-go port were added. Support for lower cost memories like 3.3V SDRAM, DDR2, and multi-level cell NAND were integrated. Also included are storage device connections P-ATA and CE-ATA. The i.MX355 is supported by companion NXP® power management ICs (PMIC), MC13892 and MMPF0100.
