GENERAL 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. Its integrated step-up converter allows operation within a supply voltage range of

2.5 to 6 V. The very low-power consumption in Power-down and

sleep modes saves battery power. A special version where the internal connections to the controller are fed outside through pins allows easy development and evaluation, together with a standard 80CL51 microcontroller.

Development tools, application report and support (hardware and software) are available.

The device can be supplied either as a masked chip with standard software handling all communication between smart card and a master controller in order to make the application easier, or as a maskable device.

Low-power smart card coupler TDA8005

FUNCTIONAL DESCRIPTION Microcontroller

The microcontroller is an 80CL51 with 256 bytes of RAM instead of 128. The baud rate of the UART has been multiplied by four in modes 1, 2 and 3 (which means that the division factor of 32 in the formula is replaced by 8 in both reception and transmission, and that in the reception modes, only four samples per bit are taken with decision on the majority of samples 2, 3 and 4) and the delay counter has been reduced from 1536 to 24.

Remark: this has an impact when getting out of PDOWN mode. It is recommended to switch to internal clock before entering PDOWN mode (see

“application report”

All the other functions remain unchanged. Please, refer to the published specification of the 80CL51 for any further information. Pins INT0, P10, P04 to P07 and P24 to P27 are used internally for controlling the smart card interface.

Mode 0 is unchanged. The baud rate for modes 1 and 3 is:

The baud rate for mode 2 is:

Supply

The circuit operates within a supply voltage range of

2.5 to 6 V. The supply pins are V Pins V

and AGND supply the analog drivers to the card

, DGND and AGND.

DDD

and have to be externally decoupled because of the large current spikes that the card and the step-up converter can create. An integrated spike killer ensures the contacts to the card remain inactive during power-up or power-down. An internal voltage reference is generated which is used within the step-up converter, the voltage supervisor, and the V

generator.

The voltage supervisor generates an alarm pulse, whose length is defined by an external capacitor tied to the DELAY pin, when V

is too low to ensure proper

DDD

operation (1 ms per 1 nF typical). This pulse is used as a RESET pulse by the controller, in parallel with an external RESET input, which can be tied to the system controller.

It is also used in order to either block any spurious card contacts during controllers reset, or to force an automatic deactivation of the contacts in the event of supply drop-out [see Sections “Activation sequence” and “Deactivation sequence (see Fig.10)”].

In the 64 pin version, this reset pulse is output to the open drain ALARM pin, which may be selected active HIGH or active LOW by mask option and may be used as a reset pulse for other devices within the application.
