5th Generation Hi-Speed USB Flash Media and CIR Controller with Integrated Card Power FETs
Datasheet
Revision 1.3 (07-12-05)
20
SMSC USB2231/USB2232
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.
