USB On-The-Go Dual Role Controllers, ISP1761

ISP1761

General Description

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

The Hi-Speed USB host controller and peripheral controller comply to 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 Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0. The OTG controller adheres to 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.

Key Features

Compliant with Universal Serial Bus Specification Rev. 2.0; supporting data 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:

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

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)

Slave DMA implementation on CPU interface to reduce the host systems CPU load

Separate IRQ, DREQ and DACK lines for the host controller and the peripheral controller

Integrated multi-configuration FIFO

Double-buffering scheme increases throughput and facilitates real-time data transfer

Integrated Phase-Locked Loop (PLL) with external 12 MHz crystal for low EMI

Tolerant I/O for low voltage CPU interface (1.65 V to 3.3 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 or low-voltage reset and block-dedicated software reset

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 µA at ambient temperature of +25 Cel

Available in LQFP128 and TFBGA128 packages

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.
