PDIUSBD12中文资料飞利浦数据手册PDF规格书

描述 Description

The PDIUSBD12 is a cost and feature optimized USB device. It is normally used in microcontroller based systems and communicates with the system microcontroller over the high-speed general purpose parallel interface. It also supports local DMA transfer.

特性 Features

■ Complies with the Universal Serial Bus specification Rev. 2.0 (basic speed)

■ High performance USB interface device with integrated SIE, FIFO memory, transceiver and voltage regulator

■ Compliant with most Device Class specifications

■ High-speed (2 Mbytes/s) parallel interface to any external microcontroller or microprocessor

■ Fully autonomous DMA operation

■ Integrated 320 bytes of multi-configuration FIFO memory

■ Double buffering scheme for main endpoint increases throughput and eases real-time data transfer

■ Data transfer rates: 1 Mbytes/s achievable in Bulk mode, 1 Mbits/s achievable in Isochronous mode

■ Bus-powered capability with very good EMI performance

■ Controllable LazyClock output during suspend

■ Software controllable connection to the USB bus (SoftConnect™)

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

■ Programmable clock frequency output
