詳細說明
General descriptionThe ISP1181 is a Universal Serial Bus (USB) interface device which complies with Universal Serial Bus Specification Rev. 1.1. It provides full-speed USB communication capacity to microcontroller or microprocessor-based systems. The ISP1181 communicates with the system’s microcontroller or microprocessor through a high-speed general-purpose parallel interface.The fully autonomous Direct Memory Access (DMA) operation - auto download, auto repeat, auto execution - removes the need for the device to re-enable or re-initialize the DMA operation every time.Features■ Complies with Universal Serial Bus Specification Rev. 1.1 and most Device Class specifications■ High performance USB interface device with integrated Serial Interface Engine (SIE), FIFO memory, transceiver and 3.3 V voltage regulator■ Interrupt endpoint can be configured in ‘rate feedback’ mode■ 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 with integrated PLL for low EMI Controllable LazyClock (24 kHz) 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■ Internal power-on and low-voltage reset circuit, with possibility of a software reset■ Operation over the extended USB bus voltage range (4.0 to 5.5 V) with 5 V tolerant I/O pads■ Operating temperature range −40 to +85 °C■ 8 kV in-circuit ESD protection for lower cost of external components■ Full-scan design with high fault coverage■ Available in a TSSOP48 package.Applications■ Personal digital assistant (PDA)■ Digital camera■ Communication device, e.g. ◆ router ◆ modem■ Printer■ Scanner.
