Oxford Semiconductor with new Single Chip USB controller
Press Release
Oxford Semiconductor Announces Industry’s First Single-Chip Combination USB and Memory Host Controller
Oxford Semiconductor Inc., a leading provider of high-performance connectivity solutions for consumer, storage and multimedia applications, today announced the industry’s first controller with full-speed host and high-speed peripheral USB connectivity combined with support for multiple storage interfaces. The OXU140CM, Oxford Semiconductor’s new all-in-one connectivity solution is ideal for consumer electronics devices that require high-performance connectivity for data transfer and access to expanded memory for additional storage. The OXU140CM supports both USB and multiple storage interfaces including the new CE-ATA (Consumer Electronics-Advanced Technology Attachment) interface, which was designed specifically for small form factor disk drives targeted at handheld and consumer electronics applications. Offering the dual benefits of full-speed host and high-speed peripheral USB connectivity, the OXU140CM offers the performance and flexibility required by consumers to transfer photos, music and video at a higher speed and in a shorter time. Multiple storage interfaces allow the OXU140CM high-speed bridging to CE-ATA, MMC and SD memory for expanded storage capabilities.
“Today’s portable consumer products require their USB to handle a broader range of media content than ever before. These products also require USB data to be efficiently transferred across a growing number of storage interfaces. The OXU140CM was specifically designed to meet this emerging industry need,” said Paul Liu, Oxford Semiconductor product marketing director. “We are well-known in the USB arena and have leveraged our USB expertise to design the first controller that supports high-performance USB, combined with support for multiple storage interfaces.”
The OXU140CM utilizes the proven design of Oxford’s TD1120, the company’s single-chip, high-speed peripheral and full-speed host USB controller, which was introduced in 2004. The high-speed USB connectivity in the OXU140CM enables a device to transfer data at high speeds when connected to a host (such as PC). The full-speed host capability enables a portable device to interface with a wide range of other USB applications such as mass storage devices (thumb drives, hard drives), digital-still-cameras and MP3 players. Oxford Semiconductor’s forward-looking design supports MMC and SD memory as well as an interface to CE-ATA, a new standard in the early stages of adoption by manufacturers of consumer electronics products.
Features provided by the OXU140CM include:
-
Two-in-one USB connectivity – Full-speed host and high-speed peripheral provides cost, board space and power savings and minimizes system design by replacing two discrete USB controllers with one single chip.
-
CE-ATA/MMC/SD memory host controller – Supports multiple storage interfaces enabling expanded mass storage for portable applications.
-
High-speed data bridging – High-speed USB peripheral data transfer to CE-ATA/MMC/SD storage devices for fast synchronization between a PC and the portable device. Improves performance and lowers CPU utilization.
-
Low power design saves battery life – a key requirement for consumer electronics devices.
-
128pin LQFP (14x14mm) and 100-ball BGA (8x8mm) – Two types of packaging offers cost and board space savings.
