Key Features
- I2C-bus controlled IC card interface.
- Supports up to two main cards (synchronous or asynchronous smart cards) and up to four Security Access Modules (SAMs).
- Dedicated microcontroller interface supply voltage (VDD(INTF)).
- Shutdown mode ensures very low power consumption when the TDA8026 is inactive.
- Programmable power reduction modes triggered when the card slots are inactive.
- VCC(n) generation via DC-to-DC converter, allowing two card slots to be fully loaded while the others are in reduced consumption mode.
- Two clock input pins: CLKIN1 for card slot 1 and CLKIN2 for card slots 2 to 5.
