UHC0J470MDD, UHC0J471MPD, UHC124

TransDimension's UHC124 is a four-port, single chip USB Host controller that is the first of a family of integrated low-cost, high-performance controllers optimized and specifically designed for embedded systems, mobile communication, and consumer products. It is a non-PCI controller that supports USB Specification Rev. 2.0 compliant full-speed (12Mb/s) and low-speed (1.5Mb/s) USB devices. It is the only non-PCI controller that has been proven to run at USB full speed, even running under a full USB stack. The UHC124 controller enables an embedded system to function as a USB Host, dramatically expanding the degree of interconnectivity and extending the applicability of USB into many new areas. In addition to silicon, development kits, USB Host Stack, device drivers for most products, and interface code to the UHC124 for numerous RTOS' are available via our wholly owned subsidiary, SoftConnex Technologies, Inc.

The UHC124 has unique, patent-pending features that are indispensable for achieving high data throughput and low interrupt rates. It is the only one on the market that is designed from the ground up for embedded applications with features like batch processing, multiple interrupt modes, separate data and descriptor memory, and double buffering. It is optimized for cost, performance and ease of development. The software/hardware co-designed architecture enables high performance while maintaining simplicity and flexibility that are critical for embedded applications. It can be interfaced to CISC or RISC microprocessors, microcontrollers, or digital signal processors (DSPs) and is ideal for providing USB host functions to a wide range of applications including mobile devices, cell phones, PDAs, point-of-sale systems, test equipment, set-top boxes, Internet appliances, as well as serving as an interface for USB to Bluetooth controllers.

The complete solutions offer the advantages of shortened time-to-market, simplified procurement and technical support from one source.
