Overview
The TDA8026ET/C3Y, produced by NXP USA Inc., is a cost-effective, analog interface designed for addressing multiple smart card slots in Point Of Sales (POS) terminals. This IC supports up to two main cards (both synchronous and asynchronous smart cards) and up to four Security Access Modules (SAMs). It is packaged in a TFBGA64 plastic thin fine-pitch ball grid array, which complies with the latest payment terminal security requirements.

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
