Product Overview

The TDA8023TT/C1,118 is a low power IC Card Interface for synchronous or asynchronous smart cards. It can be placed between the card and the microcontroller with very few external components to perform all supply, protection and control functions. It has 2 different addresses, one for each of its two registers. Each data transfer is initiated with a START condition and terminated with a STOP condition. Data transfer is unlimited in the Read mode. The information is transmitted in bytes and each receiver acknowledges with a 9th bit. Within the I²C-bus specifications, a Standard mode (100kHz clock rate) and a Fast-speed mode (400kHz clock rate) are defined. The TDA8023 operates in both fast-speed and standard modes. By definition, a device that sends a signal is called a transmitter and a device that receives the signal is called a receiver. The device that controls the signal is called the master. The devices that are controlled by the master are called slaves.
  • Power reduction modes when the card is active
  • Thermal and short-circuit protections on all card contacts
  • Automatic activation and deactivation sequences
  • Card presence input with 10ms built-in denouncing system
  • One interrupt signal INT\
  • Shutdown input for very low power consumption when the part is not used
  • DC-to-DC converter for VCC generation
