製品詳細
Features
- Two independent 6 contacts smart card interfaces
- Supply voltage to the cards: VCC = 5 V and ICC up to 60 mA or 3 V +-5pct. and ICC up to 55 mA
- Integrated DC-to-DC converter (doubler, tripler or follower) for allowing power supply from 2.7 to 6.5 V
- Independent supply voltage for interface signals (from 1.5 to 6.5 V)
- Control and status via the I²C-bus
- Four possible devices in parallel due to two I²C-bus address pins
- Electrical specifications according to ISO 7816 or EMV2000
- Automatic activation and deactivation sequences by means of integrated sequencers
- Automatic clock count and reset toggling during warm or cold reset
- Interrupt request output to the controller
- 6 kV ESD protection on cards contacts
- Automatic emergency deactivation in the event of supply drop-out, overload, overheating, card take-off or DC-to-DC malfunctioning
