ISP1761 General Description
ISP1761 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, Philips XA, Intel® StrongARM®, NEC® and Toshiba® MIPS, Motorola® 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 for reducing the host system's CPU load
` Separate IRQ, DREQ and DACK lines for the Host Controller and the Peripheral Controller
` Integrated multiconfiguration 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: VCC(5V0) (can be switched off), VCC(I/O) (permanent)
` Target total current consumption:
` Normal operation; one port in high-speed active: ICC < 100 mA when the internal charge pump is not used
` Suspend mode: ICC(susp) < 150 A at the room temperature
` Available in LQFP128 and TFBGA128 packages
` Host Controller-specific features
` High performance USB host with integrated high-speed USB transceivers;supports high-speed, full-speed and low-speed
` The EHCI core is adapted from 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 bits)
` Additional 2.5 kB separate memory for TT
` Individual or global overcurrent protection with built-in sense circuits
` Overcurrent circuitry built-in (digital or analog overcurrent protection)
` OTG Controller-specific features
` OTG transceiver: fully integrated; compliant with On-The-Go Supplement to the
` SB Specification Rev. 1.0a
` Supports HNP and SRP for OTG dual-role devices
` HNP: status and control registers for software implementation
` SRP: status and control registers for software implementation
` Programmable timers with high resolution (0.01 ms to 80 ms)-for HNP and SRP
` Supports external source of VBUS
` Peripheral Controller-specific features
` High-performance USB Peripheral Controller with integrated Serial Interface Engine (SIE), FIFO memory and transceiver
` Complies with Universal Serial Bus Specification Rev. 2.0 and most device class specifications
` Supports auto Hi-Speed USB mode discovery and Original USB fallback capabilities
` Supports high-speed and full-speed on the Peripheral Controller
` Bus-powered or self-powered capability with suspend mod
` Slave DMA, fully autonomous and supports multiple configurations
` Seven IN endpoints, seven OUT endpoints and one fixed control IN and OUT
endpoint
` Integrated 8 kB memory
` Software-controllable connection to the USB bus, SoftConnect™
