Datasheet Summary
Smartcard interface
Features
- Designed to be patible with the NDS conditional access system
- IC card interface
- 3 or 5 V supply for the IC (VDD and GND)
- Three specifically protected half-duplex bi- directional buffered I/O lines to card contacts C4, C7 and C8
- DC-DC converter for VCC generation separately powered from a 5 V ± 20% supply (VDDP and PGND)
- 3 or 5 V ± 5 % regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:
- ICC < 80 mA at VDDP = 4 to 6.5 V
- Handles current spikes of 40 nA up to 20 MHz
- Controls rise and fall times
- Filtered overload detection at approximately 120 mA
- Thermal and short-circuit protection on all...
