The ISP1362 is a single-chip Universal Serial Bus (USB) On-The-Go (OTG) controller integrated with the advanced Philips Slave Host Controller (PSHC) and the Philips ISP1181B Device Controller (DC). The USB OTG controller is compliant with On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0a. The host and device controllers are compliant with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The ISP1362 has two USB ports: port 1 and port 2. Port 1 can be hardware configured to function as a downstream port, an upstream port or an OTG port whereas port 2 can only be used as a downstream port. The OTG port can switch roles from host to peripheral, or from peripheral to host. The OTG port can become a host through the Host Negotiation Protocol (HNP) as specified in the OTG supplement. A USB product with OTG capability can function either as a host or as a peripheral. For instance, with this dual-role capability, a Personal Computer (PC) peripheral such as a printer may switch roles from a peripheral to a host for connecting to a digital camera so that the printer can print pictures taken by the camera without using a PC. When a USB product with OTG capability is inactive, the USB interface is turned off. This feature has made OTG a technology well-suited for use in portable devices.
The ISP1362 is a single‑chip USB On‑The‑Go controller that integrates a Philips Slave Host Controller and a Philips ISP1181B Device Controller. It complies with the USB 2.0 specification and the OTG supplement, supporting both full‑speed (12 Mbit/s) and low‑speed (1.5 Mbit/s) transfers.
The device offers two USB ports, configurable port 1 (downstream, upstream or OTG) and a downstream‑only port 2, up to 14 programmable endpoints, a 16‑bit data bus with 10 Mbyte/s host‑to‑device transfer, operation at 3.3 V, and temperature range –40 °C to +85 °C. It is supplied in 64‑pin LQFP and TFBGA packages.
