Introduction

The AU6465R is designed to deliver outstanding performance for data transmission between USB and compatible flash card interface. It supports USB 2.0 high-speed transferring to SD, MMC and MS. Besides, the AU6465R supports several operating systems, including MS Windows, LINUX and Mac OS. The AU6465R integrates a high performance 8051 CPU as well as a splendidly efficient DMA hardware engine and internal 3.3V to 1.8V regulators. The AU6465R provides manufacturers not merely BOM cost saving with the minimal numbers of components needed on the PCB but also smaller circuit board with the 28-pin QFN (5×5mm) package. In addition to high-speed 8051 CPU embedded and DMA hardware engine integrated, the AU6465R is fully compliant with USB Device Class Definition for Mass Storage and Bulk-Transport V1.0. Combination with these features, the AU6465R provides a completely ultra high performance USB2.0 card reader solution in a single chip. AU6465R maximizes performance with the latest SD/MS card specification available from the industry. Based on the features of low pin count and high performance characteristic, AU6465R supports a wide range of flash card reader applications used to digital camera, MP3 players, cell phone, PDA, camcorder, GPS device and so on to store many types of data, such as digital map, digital photos and compressed music.
