OXU121HP
Overview
- Single‐chip USB OTG full‐speed host and high‐speed peripheral controller Replaces two‐chip system Reduces system cost and board space Minimizes system design complexity and power consumption Simultaneous host and peripheral operation
- Compatible with the Universal Serial Bus Specification, Revision 2.0 and the On‐The‐Go Supplement to the USB Specification 2.0, Revision 1.0 Single 3.3 V power supply, flexible I/O voltage of 1.65 V to 3.6 V (LVCMOS/TTL) to interface to a wide range of MCUs Low power operation, suitable for mobile applications 30 mA (max) for host operation 75 mA (max) for peripheral operation * * * *
- Power saving mode for the host controller and suspend mode for peripheral controller Integrated on‐chip charge pump, supports up to 100 mA of current, enables support for broad range of USB devices Small package and footprint saves board space 7×7 mm BGA, 84‐ball, RoHS compliant 12×12 mm LQFP, 100‐pin, RoHS compliant * * * *
- 16‐bit memory mapped interface can gluelessly interface to most popular microprocessors and DSPs Fast microprocessor access cycle and double/multi‐buffering support for all four types of USB transfers Two DMA (slave) channels for the high‐speed peripheral controller, lowering CPU utilization Integrated PLL supports external crystal or crystal oscillators of 12 MHz and 30 MHz, for system flexibility 16 Kbytes of on‐chip SRAM, optimized buffer size for performance/cost DS-0040 Aug 06 External--Free Release 1
