Key Features
- I2C-bus controlled IC card interface in a TFBGA64 package.
- Supply voltage between 2.7 V and 5.5 V.
- 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: two card slots can be fully loaded, the three others in reduced consumption mode.
- Two clock input pins: CLKIN1 for card slot 1 and CLKIN2 for card slots 2 to 5.
- Two transparent I/O lines on microcontroller side, deactivation at power-off; threshold internally fixed.
- Card presence input with a 17.8 ms (typical) built-in debouncing system on card slots 1 and 2.
- One interrupt signal (IRQN).
Applications
- Point Of Sale terminals.
- Multiple SAM contact readers).
