General description

The ISP1181B is a Universal Serial Bus (USB) peripheral controller that complies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s). It provides full-speed USB communication capacity to microcontroller or microprocessor-based systems. The ISP1181B communicates with the system’s microcontroller or microprocessor through a high-speed general-purpose parallel interface.

Features

■ Complies with Universal Serial Bus Specification Rev. 2.0 and most Device Class specifications

■ Supports data transfer at full-speed (12 Mbit/s)

■ High performance USB peripheral controller with integrated Serial Interface

Engine (SIE), FIFO memory, transceiver and 3.3 V voltage regulator

■ High speed (11.1 Mbyte/s or 90 ns read/write cycle) parallel interface

■ Fully autonomous and multi-configuration DMA operation

■ Up to 14 programmable USB endpoints with 2 fixed control IN/OUT endpoints

■ Integrated physical 2462 bytes of multi-configuration FIFO memory

■ Endpoints with double buffering to increase throughput and ease real-time data transfer

■ Seamless interface with most microcontrollers/microprocessors

■ Bus-powered capability with low power consumption and low ‘suspend’ current

■ 6 MHz crystal oscillator input with integrated PLL for low EMI

■ Controllable LazyClock (100 kHz ± 50 ) output during ‘suspend’

■ Software controlled connection to the USB bus (SoftConnect?)

■ Good USB connection indicator that blinks with traffic (GoodLink?)

■ Clock output with programmable frequency (up to 48 MHz)

■ Complies with the ACPI?, OnNow? and USB power management requirements
