General Description

The SMSC USB2250/50i/51/51i is a USB 2.0 compliant, high speed Mass Storage Class Peripheral Controller intended for reading and writing to more than 24 popular flash media formats from the CompactFlash® (CF), SmartMediaTM (SM), xD Picture CardTM (xD)1, Memory StickTM (MS), Secure Digital (SD), and MultiMediaCardTM (MMC) families.

The SMSC USB2250/50i/51/51i is a fully integrated, single chip solution capable of ultra high performance operation. Average sustained transfer rates exceeding 35MB/s are possible if the media and host can support those rates.

General Features

128-pin VTQFP (14x14mm) lead-free RoHS compliant package

Targeted for applications in which single or "combo" media sockets are used

Supports multiple simultaneous card insertions

Flexible assignment of number of LUNs and how card types are associated with the LUNs

Hardware-controlled data flow architecture for all selfmapped media

Pipelined hardware support for access to non-self- mapped media

Product name with “i” denotes the version that supports the industrial temperature range of -40ºC to 85ºC

Chapter 5 Pin Descriptions

This section provides a detailed description of each signal. The signals are arranged in functional groups according to their associated interface.

The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “n” is not present before the signal name, the signal is asserted at the high voltage level.

The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive.
