ISP1763A - usb otg controller

Single-chip Hi-Speed OTG controller

The ISP1763A is a single-chip Hi-Speed USB -On-The-Go (OTG) controller supporting data transfer speeds of up to 480 Mbit/s and can be used to implement a dual-role USB device in any application, USB host or USB peripheral. It is integrated with the ST-Ericsson advanced slave host controller and the slave peripheral controller which comply with the Universal Serial Bus Specification Rev 2.0.

High flexibility with multiple port and interface support

Key Features

• Compliant with:    
  • Universal Serial Bus Specification Rev. 2.0
  • On-The-Go Supplement to the USB Specification Rev. 1.3
• Small font-factor for portable applications; available in HVQFN64 and TFBGA64 Restriction of Hazardous Substances (RoHS) compliant, halogen-free and lead-free packages
• Low power consumption for portable applications
• Two USB ports:
  • Port 1: OTG, host, or peripheral port
  • Port 2: Host port only (supports SRP detection)
• Supports OTG HNP and hardware SRP
• Supports 8-bit or 16-bit CPU bus interface
• Flexible compatibility. Can interface with various types of processors:
  • NOR Flash interface (multiplexed mode)
  • NAND Flash interface (multiplexed mode)
  • General multiplex interface
  • SRAM interface
• Integrated Phase-Locked Loop (PLL) supports external 12 MHz, 19.2 MHz, and 24 MHz crystal, and direct clock source
• Supports interfacing I/O voltage of 1.8 V or 3.3 V; separate I/O voltage supply pins minimize crosstalk
• Internal voltage regulator supplies 1.2 V to the digital core
• 3.0 V to 3.6 V supply voltage input range for the internal USB transceiver
• Supports hybrid power mode; when VCC is not present and VCC(I/O) is powered
• Host controller-specific features:
  • Integrated 24 kB high-speed memory
  • Individual over current protection in deep-suspend mode
• Peripheral controller-specific features:
  • Integrated 4 kB memory to support 7 IN endpoints, 7 OUT endpoints, and 1 fixed control IN/OUT endpoint
  • VBUS detection in deep-suspend mode
• OTG controller-specific features:
  • Supports OTG HNP and SRP using status and control registers for the software implementation in OTG dual-role devices
  • Integrated VBUS voltage comparators
  • Integrated cable (ID) detector
  • Programmable timers with high resolution (0.01 ms to 80 ms)

Applications

The ISP176A can be used to implement a dual-role USB device in any application, USB host or USB peripheral, depending on the cable connection. If the dual-role device is connected to a typical USB peripheral, it behaves like a typical USB host. The dual-role device can also be connected to a PC or any other USB host and behave like a typical USB peripheral.
