1.3.12 PCMCIA controller_ ENE CB1410 + ENE CP2211
CP2211 is a single slot PCMCIA and CardBus power switch. It integrates
control logic, low switching resistance MOSFET, over current alarm and
over temperature auto shutdown circuits. It can deliver 3.3V or 5V to PC
Card xVCCOUT and 3.3V, 5V or 12V to PC Card xVPPOUT. The output
current is up to 1A for xVCCOUT and 250mA for xVPPOUT. The power is
controlled by 4-wire parallel data interface VCCD0Z, VCCD1Z, VPPD0
and VPPD1.
