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 Freescale power management ICs (PMIC), MC13892 and MMPF0100.ARM1136JF-S™532 MHz maximum speed128 KB Integrated SRAM16 KB I/D L1 Cache, 128 KB L2 cacheMLBESAIImage Processing Unit (IPU)LCD Controller10/100 EthernetMAC 2 x FlexCan modulesHS OTG + PHY, HS Host + PHY3 x UART, 2 x CSPI, 3 I2C, 2 SSI/I2SP-ATA/CE-ATAOptimized for up to 24-bit-per-pixel WVGACMOS/CCD sensor interfaceVector Floating Point UnitExternal memory interface: mSDRAM/SDRAM, mDDR/DDR2, NOR, SLC/MLC NAND3.3V general purpose I/O
