ISP1761

General description

The ISP1761 is a single-chip Hi-Speed Universal Serial Bus (USB) On-The-Go (OTG) Controller integrated with advanced NXP slave host controller and the NXP ISP1582 peripheral controller.

The Hi-Speed USB host controller and peripheral controller comply to Ref. 1 "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 Ref. 2 "Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0". The OTG controller adheres to Ref. 3 "On-The-Go Supplement to the USB Specification Rev. 1.3".

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.

• Supports suspend and remote wake-up
• Built-in overcurrent circuitry (analog overcurrent protection)
• Hybrid-power mode: V_CC(5V0) (can be switched off), V_CC(I/O) (permanent)
• Target total current consumption:
  • Normal operation; one port in high-speed active: I_CC < 100 mA when the internal charge pump is not used
  • Suspend mode: I_CC(susp) < 150 uA at ambient temperature of +25 Cel
• Available in LQFP128 and TFBGA128 packages
• Host controller-specific features
  • High performance USB host with integrated Hi-Speed USB transceivers; supports high-speed, full-speed and low-speed
  • EHCI core is adapted from Ref. 2 "Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0"
  • Configurable power management
  • Integrated TT for Original USB peripheral support on all three ports
  • Integrated 64 kB high-speed memory (internally organized as 8 k x 64 bit)
  • Additional 2.5 kB separate memory for TT
  • Individual or global overcurrent protection with built-in sense circuits
  • Built-in overcurrent circuitry (digital or analog overcurrent protection)
• OTG controller-specific features
  • OTG transceiver: fully integrated; adheres to Ref. 3 "On-The-Go Supplement to the USB Specification Rev. 1.3"

Applications

The ISP1761 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.
