TDA8005 Description
The TDA8005 is a low cost card interface for portable smart card readers. Controlled through a standard serial interface, it takes care of all ISO 7816 and GSM11-11 requirements. It gives the card and the set a very high level of security, due to its special hardware against ESD, short-circuiting, power failure, etc.
TDA8005 Key Features
- VCC generation (5 V ±5%, 20 mA maximum with controlled rise and fall times)
- Clock generation (up to 8 MHz), with two times synchronous frequency doubling
- Clock STOP HIGH, clock STOP LOW or 1.25 MHz (from internal oscillator) for cards power-down mode
- Specific UART on I/O for automatic direct/inverse convention settings and error management at character level
- Automatic activation and deactivation sequences through an independent sequencer
- Supports the protocol T = 0 in accordance with ISO 7816, GSM11.11 requirements (Global System for Mobile munication); an
- Several analog options are available for different
