F75111
1. General Description
F75111 is a low power general purpose IO chip providing 20 GPIO. Most GPIO pins can be
programmed to be power LED. Level or pulse modes can be programmed by registers. Two power-down
modes (manual or Smart) can be selected to save power and control the total consumption under 10uA, so
F75111 can fit the requirement of mobile device such as Smart Phone, PDA or cell phone.
