Introduction
ND3260 is a highly integrated, NAND Flash/Smart Media/Memory Stick/Memory Stick PRO/Compact Flash/IBM MicroDrive/Secure Digital/MultiMedia/xD-Picture Card, USB 2.0 High Speed compatible reader/writer controller IC. It combines an internal program/data memory and a variety of peripherals on a single monolithic SOC (System-On-Chip). With an USB 2.0 HS/FS device controller supporting bus-power capability and remote wake-up function, ND3260 is able to provide up to 480 Mbps transfer rate on USB bus when accessing flash memory cards. Combining USB's plug and play function and Neodio's device driver-less solution (conforms to USB Mass Storage Class Specification), ND3260

ensures an effortless install-use experience for customers. ND3260 also supports the latest Memory Stick PRO and xD-Picture Card with hardwired parallel bus circuits to achieve maximum throughput. In Application Programming (IAP), which enables on-line software programming through USB port, makes it possible for the customers to update their flash card reader/writer functionalities on site. Both mask-ROM and IAP-enabled versions are available for a best choice of cost and performance for flash card reader/writer solution. Innovative In Device Disk (patent pending) technology provides a flexible and user-friendly function and the built in Digital Encryption System (DES) module also provides a high performance data encryption/decryption mechanism for all flash memory cards. With a 128-pin LQFP package and only a few external passive components required, ND3260 is the best solution for USB 2.0 HS flash card reader/writer applications.
Features
Internal maximum 32K x 8 code memory Hardwired Error Correction Code (ECC) function Two 16-bit timers/counters 12 vectors interrupt structure with 2 priority levels Built-in watchdog timer High performance NA-16 (Neodio Architecture-16) access for data exchange 480Mbps Hi-speed USB interface complies with ver. 2.0 HS standard Three types of USB data pipes supported: Interrupt, Control and Bulk USB bus power capability Support USB remote wake-up function Support USB suspend Resume from power down by either reset or interrupt Internal PLL function provides 30MHz frequency for USB operation Low EMI (ALE is inhibited automatically when executing internal code) Flash card interfaces supporting various memory storage devices: NAND Flash/Compact Flash Card/IBM MicroDrive/Smart Media Card/MultiMedia Card/Security Digital Card/Memory Stick Card/Memory Stick PRO Card and xD-Picture Card etc
