ISP1763A
Hi-Speed USB OTG controller
Rev. 02 — 24 February 2011
Product data sheet
1. General description
The ISP1763A is a single-chip Hi-Speed Universal Serial Bus (USB) On-The-Go (OTG)
controller integrated with the advanced ST-Ericsson’s slave host controller and the
ST-Ericsson’s ISP1582 peripheral controller.
The Hi-Speed USB host controller and peripheral controller comply with 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. 1.3.
The ISP1763A has two USB ports. Port 1 can be configured to function as a downstream
port, an upstream port, or as an OTG port; port 2 is always configured as a downstream
port. Port 2 supports Session Request Protocol (SRP) detection from the B-device. The
OTG port supports Host Negotiation Protocol (HNP) and SRP as specified in On-The-Go
Supplement to the USB Specification Rev. 1.3.
The ISP1763A support multiple bus interfaces with 8-bit or 16-bit bus. The ISP1763A can
interface to processors with digital I/O voltages of 1.8 V or 3.3 V.
