4th Generation USB2.0 Flash Media Controller with Integrated Card Power FETs
Datasheet
Revision 1.76 (09-24-04)
15
SMSC USB2228
DATASHEET
■
Hot-insertion capable card connectors are required for all flash media. It is required for SD
connector to have Write Protect switch. This allows the chip to detect MMC card.
■
nMCE is normally asserted except when the 8051 is in standby mode.
