5th Generation Hi-Speed USB Flash Media & IrDA Controller with Integrated Card Power FETs
Datasheet
Revision 1.2 (02-21-05)

SMSC USB2229/USB2230
DATASHEET
Notes:
■
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.
