Features
- Integrated circuit smart card interface in an HVQFN24 package.
- 5 V, 3 V or 1.8 V smart card supply.
- Very low power consumption in Deep Shutdown mode.
- Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8).
- VCC regulation:.
- 5 V, 3 V or 1.8 V 5 % using two low ESR multilayer ceramic capacitors: one of 220 nF and one of 470 nF.
- current spikes of 40 nA/s (VCC = 5 V and 3 V) or 15 nA/s (VCC =1.8 V) up to 20 MHz, with controlled rise and fall.
