standards including ISO7816-3, EMV for smart card standard. The interface may communication

with computer uses CCID protocol through USB.

The ST2201U has one Low Voltage Detector (LVD) for power management. The status of external

power can be detected and reported to the management software. Watch Dog Timer (WDT) is also

built-in and is an essential function for a good design.

Power consumption is another big issue for a battery-powered device. The ST2201U has different

power down modes and clock switch scheme to make the consuming power as low as possible.

The ST2201U equips an ICE debug interface for efficient development flow. Besides hardware

emulator, a software simulator is also supported to save programmers setting up the system and

makes programming be at anywhere.

With these integrated functions inside, the ST2201U single chip microcontroller is a right solution for

Smart Card reader, PDA, translator, databank and other consumer products.
