... PDAs, consuming only 10nA in stop mode. See Figure 1 for a functional diagram. The DS8113 is a dual-supply device. The supply pins for the device are VDD, GND, VDDA, and PGND. V should be in the range of 2.7V to 6.0V, and is the sup- ply for signals that interface with the host controller ...

... Current to and from the card I/O lines is limited internally to 15mA. The maximum frequency on these lines is 1MHz. The DS8113 powers up with the card interface in the inactive mode. Minimal circuitry is active while waiting for the host to initiate a smart card session. • All card contacts are inactive (approximately 200Ω ...

... If both 1_8V CC voltages: CC and 5V/3V are high with CMDVCC high at the same time, the DS8113 enters stop mode. To avoid acciden- tal entry into stop mode, the state of 1_8V and 5V/3V must not be changed simultaneously. A minimum delay of 100ns should be observed between changing the CC states of 1_8V and 5V/3V ...
