Part Descriptions

NET 2270

The NetChip™ NET 2270 8/16-bit USB 2.0 Hi-Speed programmable peripheral controller is optimized for devices such as printers, scanners, digital cameras, mass storage, and audio products. The device supports both USB 1.1 (12Mbps) and USB 2.0 (480Mbps), with automatic detection and complete backward compatibilities. The NET 2270 is offered in a 10 x 10mm 64-pin TQFP. This device is available in lead-free packaging.

NET 2280

The NET 2280 PCI to Hi-Speed USB 2.0 programmable peripheral controller is a highly integrated single chip device optimized for data transfer between a PCI bus and USB. NET 2280 is the ideal interface for intelligent Hi-Speed USB 2.0 peripherals that use PCI as the internal bus interface or a PCI-based local CPU. The NET 2280 is offered in a 14 x 14mm 120-pin TQFP or 8 x 8mm 121-ball FPBGA. This device is available in lead-free packaging.

NET 2890

The NetChip™ NET 2890 Full-speed USB Peripheral Controller allows control, isochronous, bulk or interrupt transfers on each of the 4 user defined endpoints between a generic local bus and a Universal Serial Bus (USB). The NET 2890 supports the connection between a host computer and an intelligent peripheral such as a printer, PDA, Communications device, digital camera or scanner. This device is a full-speed USB peripheral controller, supporting USB bandwidth of up to 12Mb/sec. The NET 2890 is offered in a 9 x 9mm 48-pin PQFP. This device is available in lead-free packaging.

OXU121HP

The PLX OXU121HP is a single-chip full-speed host, high-speed peripheral and On-the-Go (OTG) controller enabling embedded systems to operate as both USB host and peripheral. This dramatically expands the degree of interconnectivity and extends the applicability of USB into many areas, such as mobile communications, consumer electronics and printer applications. The combination of the OXU121HP's high-speed peripheral and full-speed host controller enables users to perform high speed USB data transfer for peripheral connectivity when connected to a host device, while operating at full speed in host mode operation to maximize system battery life in a mobile environment.

OXU140CM

The PLX OXU140CM is a single-chip USB On-The-Go (OTG) controller that incorporates a full-speed host controller, a high-speed peripheral controller and multi-storage interface support, which includes a CE-ATA HDD controller and a MMC/SD memory controller. The OXU140CM balances flexibility, performance, power usage, and cost to provide the ideal USB controller for a wide variety of applications.

OXU200

The PLX OXU200 is a low-cost, single-port, USB high speed peripheral controller that enables embedded systems to perform high-speed USB data transfer for peripheral connectivity when connected to a USB host. The low-power, high-performance design and small package size makes the OXU200 ideal for adding high-speed USB into a broad range of mobile consumer electronics, including cell phones, portable GPS, and portable media players.

OXU210HP

The PLX OXU210HP is a single-chip, high-speed USB host and high-speed USB peripheral controller with integrated transceivers. It is the fourth controller in the family of integrated, low-cost, high-performance, On-The-Go (OTG) controllers that have been specifically designed for embedded systems.

TDOTG242LP

The TDOTG242LP allows your product to operate as either a USB host or a USB peripheral, and can perform both functions simultaneously, enabling many new applications for USB, especially in low power, mobile markets. It is the second controller in the family of integrated low-cost, high-performance; OTG controllers optimized and specifically designed for mobile and consumer products. Applications include mobile and consumer electronics products such as cellular phones, palmtop PCs, PDAs, MP3 players, digital still cameras, portable media players and mobile storage products.

TDUHC122

PLX's TDUHC122 is a two-port, single chip USB host controller that is specifically designed for embedded systems, mobile communications, and consumer products. It is a non-PCI controller that supports full speed(12Mb/s) and low-speed (1.5Mb/s) USB devices. Low interrupt rates, low CPU overhead and low software overhead are essential criteria for embedded designs, and the TDUHC122 excels at all three metrics. 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, internet appliances, as well as serving as an interface for USB to Bluetooth controllers.

TDUHC124

PLX's TDUHC124 is a four-port, single chip USB host controller that is specifically designed for embedded systems, mobile communications, and consumer products. It is a non-PCI controller that supports full speed(12Mb/s) and low-speed (1.5Mb/s) USB devices. Low interrupt rates, low CPU overhead and low software overhead are essential criteria for embedded designs, and the TDUHC124 excels at all three metrics. 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, internet appliances, as well as serving as an interface for USB to Bluetooth controllers.
