Key Features
- I2C-bus controlled IC card interface in a 64-TFBGA package.
- 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.
- Two transparent I/O lines on the microcontroller side.
Applications
The TDA8026ET/C2,518 is primarily used in Point Of Sales (POS) terminals and other payment systems that require multiple smart card slot interfaces. It is also suitable for applications that need to interface with Security Access Modules (SAMs) and other secure payment solutions.
