The ISP1761 is a single-chip Hi-Speed Universal Serial Bus (USB) On-The-Go (OTG) Controller integrated with the advanced Philips Slave Host Controller and the Philips ISP1582 Peripheral Controller. The Hi-Speed USB Host Controller and Peripheral Controller comply to Universal Serial Bus Specification Rev. 2.0 and support data transfer speeds of up to 480 Mbit/s. The Enhanced Host Controller Interface (EHCI) core implemented in the Host Controller is adapted from Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0. The OTG controller is compliant with On-The-Go Supplement to the USB Specification Rev. 1.0a. The ISP1761 has three USB ports. Port 1 can be configured to function as a downstream port, an upstream port or an OTG port; ports 2 and 3 are always configured as downstream ports. The OTG port can switch its role from host to peripheral, and peripheral to host. The OTG port can become a host through the Host Negotiation Protocol (HNP) as specified in the OTG supplement.
The ISP1761 is a single‑chip Hi‑Speed USB On‑The‑Go (OTG) controller that integrates a Philips Slave Host Controller and a Philips ISP1582 Peripheral Controller. It supports USB Specification Rev. 2.0 with data rates up to 480 Mbit/s and can operate in host, peripheral or dual‑role OTG modes across three USB ports.
Key features include an integrated Transaction Translator, multiple power‑management options, programmable timers for HNP/SRP, 64 kB of high‑speed memory, and support for a wide range of CPU interfaces. The device is offered in LQFP128 and TFBGA128 packages and is suitable for applications such as mobile phones, digital cameras, MP3 players, printers, and mass‑storage devices.
