4th Generation USB2.0 Flash Media Controller with Integrated Card Power FETs
Datasheet
SMSC USB2227/USB2228
23
Revision 1.77 (06-13-05)
DATASHEET
Note 7.3
Output leakage is measured with the current pins in high impedance.
Note 7.4
See Appendix A for USB DC electrical characteristics.
Note 7.5
The Maximum power dissipation parameters of the package should not be exceeded
Note 7.6
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 9.1, “GPIO Usage (ROM Rev 0x00),” on page 26
.
