USB2250/50i/51/51i

Ultra Fast USB 2.0 Multi-Slot Flash Media Controller

PRODUCT FEATURES

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

formats from the Picture Card

CompactFlash® (CF), SmartMedia

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 worki ng with a mixture of “active low” and “active high” signals. The term assert, or assertion, indi cates 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 ina ctive.

This is the other terminal of the crystal, or it is left open when an external clock source is used to drive XTAL1(CLKIN). It may not be used to drive any external circuitry other than the crystal circuit.

I/O12PD CLK_SEL[1:0]: During nRESET assertion,

these pins will select the operating frequency of the external clock, and the corresponding weak pull-down resistors are enabled. When nRESET is negated, the value on these pins will be internal latched and these pins will revert to MA[1:0] functionality; the internal pull-downs will be disabled.

CLK_SEL[1:0] = '00'. 24MHz CLK_SEL[1:0] = '01'. RESERVED CLK_SEL[1:0] = '10'. RESERVED CLK_SEL[1:0] = '11'. 48MHz

Note: If the latched value is '1', then the

corresponding MA pin is tri-stated when the chip is in the powerdown state.

If the latched value is '0', then the corresponding MA pin will function identically to the MA[15:3] pins at all times (other than during nRESET assertion).

Note 7.1 Stresses above the specified parameters may cause permanent damage to the device.

This is a stress rating only and functi onal operation of the device at any condition above those indicated in the operation sections of this specification is not implied .

Note 7.2 When powering this device from laboratory or system power supplies, it is important that

the Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists, it is suggested that a clamp circuit be used.

Note 7.9 The assignment of each Integrated Card Power FET to a designated Card Connector is

controlled by both firmware and the specific board implementation. Firmware will default to the settings listed in Table 10.1, “USB2250/50i/51/51i GPIO Usage (ROM Rev 0x00),” on

page 35.

Note 7.10 The 3.3V supply should be at least at 75% of its operating condition before the 1.8V supply

is allowed to ramp up.
