TDA8026 Overview
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.
TDA8026 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
- Two clock input pins: CLKIN1 for card slot 1 and CLKIN2 for card slots 2 to 5
- Five protected, half-duplex, bidirectional, buffered I/O lines with current limitation at
- Two I2C-bus controlled auxiliary I/O lines
- VCC(n) regulation on all card slots at ICC 55 mA
