产品特点 Features

• Automotive qualified in accordance with AEC-Q100
• The host controller portion of the SAF1760 complies with Universal Serial Bus Specification Rev. 2.0
• The EHCI portion of the SAF1760 is adapted from Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0
• Contains three integrated Hi-Speed USB transceivers that support high-speed, full-speed and low-speed modes
• Integrates a TT for original USB (full-speed and low-speed) device support
• Up to 64 kB internal memory (8 k x 64 bit) accessible through a generic processor interface; operation in multitasking environments is made possible by the implementation of virtual segmentation mechanism with bank switching on task request
• Generic processor interface, non-multiplexed and variable latency, with a configurable 32-bit or 16-bit external data bus; the processor interface can be defined as variable-latency or SRAM type (memory mapping)
• Slave DMA support to reduce the load of the host system CPU during the data transfer to or from the memory
• Integrated Phase-Locked Loop (PLL) with a 12 MHz crystal or an external clock input
• Integrated multi-configuration FIFO
• Optimized msec-based or multi-msec-based Proprietary Transfer Descriptor (PTD) interrupt
• Tolerant I/O for low voltage CPU interface (1.65 V to 3.6 V)
• 3.3 V-to-5.0 V external power supply input
• Integrated 5.0 V-to-1.8 V or 3.3 V-to-1.8 V voltage regulator (internal 1.8 V for low-power core)
• Internal power-on reset and low-voltage reset
• Supports suspend and remote wake-up
• Target current consumption:
  • Normal operation; one port in high-speed active: ICC< 100 mA
  • Suspend mode: ICC(susp)< 150 μA at room temperature
• Built-in configurable overcurrent circuitry (digital or analog overcurrent protection)

应用

The SAF1760 can be used to implement a Hi-Speed USB compliant host controller connected to most of the CPUs present in the market today, having a generic processor interface with de-multiplexed address and data bus. This is because of the efficient slave-type interface of the SAF1760.
