Silicon Interfaces Announces USB On-The-Go (OTG) Intellectual Property

CAMPBELL, Calif., July 20, 2005 - Silicon Interfaces, a high-end design services and leading provider for IP’s in Europe, USA and Japan, under their IP Development Program - Silicon Cores: Core to the Intelligent Systems™, today announced the availability of USB OTG intellectual property (IP). The SI22USB10 USB OTG IP increases the portfolio of Silicon Interfaces IP’s.

It is a single core solution incorporating USB-OTG operating in Link Layer of Open System Interconnect (OSI) which significantly reduces the time and cost of implementing complex USBOTG target system designs. The SI22USB10 USB OTG is user-configurable & individually programmable for Bulk/Interrupt or Isochronous transfers. Access to the FIFOs associated with these endpoints and to the internal control / status registers is either via an 8-bit micro-controller bus.

The USB On-The-Go specification has been introduced to provide a Low-cost connectivity solution for consumer portable devices such as mobile phones, PDAs, digital still cameras and MP3 players.

SI22USB10 USB OTG Features

• Dual Role Device: Operates either as a function controller for a USB peripheral or as the host/peripheral in point-to-point communications with another USB function.
• Complies with the USB standard for Full-Speed (12 Mbps), High-Speed (480 Mbps) functions and with the On-The-Go supplement to the USB 2.0 specification.
• Supports point-to-point communication with a Full-Speed or High-Speed device
• Supports both Session Request Protocol (SRP) and Host Negotiation Protocol (HNP).
• Supports Dataline Pulsing for A device SRP Detection
• UTMI+ Level 1 Transceiver Macrocell Interface.
• Supports 8-bit mode of operation
• Supports 3 Endpoints
• Endpoint 0 INOUT
• Endpoint 1 IN
• Endpoint 2 OUT
• It supports 256bytes for EP0 & 4 Kbytes for other endpoints.
• Supports Suspend and Remote Resume signaling.

Availability The SI22USB10 USB OTG is available now and as per requirements can be delivered with 16-bit UTM Interface.

About USB On-The- Go

USB-OTG function controller is a highly integrated USB-OTG solution for USB-OTG applications. The SI22USB10 is an USB-OTG Function controller core designed as per USBOTG specification, which is a supplement to USB 2.0 specification. It has the standard UTMI+ interface at host end and a generic microcontroller interface at the device end. It is a single core solution incorporating USB OTG operating in Link Layer of Open System Interconnect (OSI) which significantly reduces the time and cost of implementing complex USB OTG target system designs.
