Low-power smart card coupler
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 communication); and EMV banking specification approved for Final GSM11.11 Test Approval (FTA) • Several analog options are available for different applications (doubler or tripler DC/DC converter, card presence, active HIGH or LOW, threshold voltage supervisor, etc. • Overloads and take-off protections • Current limitations in the event of short-circuit • Special circuitry for killing spikes during power-on or off • Supply supervisor • Step-up converter (supply voltage from 2.5 to 6 V) • Power-down and sleep mode for low-power consumption • Enhanced ESD protections on card side (6 kV minimum) • Control and communication through a standard RS232 full duplex interface • Optional additional I/O ports for: – keyboard – LEDs – display – etc. • 80CL51 microcontroller core with 4 kbytes ROM and 256-byte RAM. APPLICATIONS
TDA8005
• Portable smart card readers for protocol T = 0 • GSM mobile phones. 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.
