NXP Semiconductors TDA8026
The TDA8026 is a cost-effective, analog interface for addressing multiple smart card slots in a Point Of Sales (POS) terminal. It can address up to two main cards (synchronous or asynchronous smart cards supported) and up to four Security Access Modules (SAMs). Its packaging supports the latest payment terminal security requirements.| Part No. | TDA8026 |

FEATURES AND BENEFITS
● 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, one for card slot 1 and the other for card slots 2 to 5
● Five protected, half-duplex, bidirectional, buffered I/O lines with current limitation at 15 mA and a maximum frequency 1 MHz
● Two I2C-bus controlled auxiliary I/O lines
● VCC(n) regulation on all card slots at ICC 55 mA:
● 5 V, 3 V or 1.8 V 5 %
● Current spikes of 40 nAs up to 20 MHz for 5 V cards with controlled rise and fall...
