1 System Overview
1.1 Introduction
This guide is for those who want to implement HCC Embedded's USB host stack with NXP Semiconductors'
SAF1761 USB host controllers. The NXP devices supported are the SAF1761 and also the legacy products
ISP1760, ISP1761, and ISP1763.
The SAF1761 includes a USB host controller and a USB device controller. The USB device controller is
actually an ISP1582, for which we provide a separate driver. These two drivers can be used together as
required. This manual only covers the USB host functionality of the SAF1761. The ISP1582 is covered in
the .
USB Device Low Level Driver for ISP1582 User Guide
The SAF1761 module provides a high speed USB 2.0 host controller which provides both full and low speed
USB functions. The controller can handle all USB transfer types and, in conjunction with the USB host
stack, can be used with any USB class driver.
The position of the host controller within the USB stack is shown below:

1.2 Feature Check
The main features of the host controller are the following:
Conforms to the HCC Advanced Embedded Framework.
Designed for integration with both RTOS and non-RTOS based systems.
Integrated with the HCC USB Host stack and all its class drivers.
Supports NXP Semiconductors' SAF1761 host controllers and also the legacy ISP1760, ISP1761,
and ISP1763 host controllers.
Supports multiple simultaneous SAF1761 controllers, each with multiple devices attached.
Can work together with HCC's USB device controller for the ISP1582.
Supports all USB transfer types: control, bulk, interrupt, and isochronous.
