1. General description

2. Features

The SAF1761 is a single-chip Hi-Speed Universal Serial Bus (USB) On-The-Go (OTG)

Controller integrated with advanced NXP slave host controller and the peripheral

controller.

The Hi-Speed USB host controller and peripheral controller comply to

Serial Bus Speciﬁcation Rev. 2.0”

The Enhanced Host Controller Interface (EHCI) core implemented in the host controller is

adapted from

Bus Rev.

Speciﬁcation Rev.

The SAF1761 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.

Hi-Speed Universal Serial Bus On-The-Go controller

Rev. 01 — 18 November 2009

Automotive qualiﬁed in accordance with AEC-Q100

Compliant with

transfer at high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)

Integrated Transaction Translator (TT) for original USB (full-speed and low-speed)

peripheral support

Three USB ports that support three operational modes:

Supports OTG Host Negotiation Protocol (HNP) and Session Request Protocol (SRP)

Multitasking support with virtual segmentation feature (up to four banks)

High-speed memory controller (variable latency and SRAM external interface)

Directly addressable memory architecture

Generic processor interface to most CPUs, such as Hitachi SH-3 and SH-4, NXP XA,

Intel StrongARM, NEC and Toshiba MIPS, Freescale DragonBall and PowerPC

Reduced Instruction Set Computer (RISC) processors

Conﬁgurable 32-bit and 16-bit external memory data bus

Supports Programmed I/O (PIO) and Direct Memory Access (DMA)

Mode 1: Port 1 is an OTG controller port, and ports 2 and 3 are host controller

ports

Mode 2: Ports 1, 2 and 3 are host controller ports

Mode 3: Port 1 is a peripheral controller port, and ports 2 and 3 are host controller

ports
