描述 Description

GENERAL DESCRIPTION
The TDA8030; TDA8031 is a bus powered full-speed USB device. All analog and digital functions for an EMV
compliant Smart Card Reader are built-in. The embedded 83C51 microcontroller has 16 kbytes EPROM (ROM for TDA8031), 256 bytes RAM and 512 bytes of AUXRAM.FEATURES
• 83C51 core with 16 kbytes EPROM (ROM); 256 bytes RAM; 512 bytes AUXRAM; Timer 0,1, 2 and enhanced UART
• Full speed USB interface device which complies with USB 1.1 specification; accessible with MOVX instructions
• Control input and output; 1 generic input and output and 2 generic input end-points
• Compatible with bus powered and suspend mode supply current requirements
• Specific ISO7816 UART; accessible with MOVX instructions for automatic convention processing; variable baud rate through frequency or division ratio programming; error management at character level for T = 0 protocol; extra guard time register
• VCCgeneration (5 or 3 V maximum current 55 mA or 1.8 V maximum current 35 mA) with controlled rise and fall times; current limitation and overload detection at 100 mA
• Cards clock generation with three times synchronous frequency doubling (12, 6, 3 and 1.5 MHz)
• Cards clock STOP HIGH or LOW or 1.25 MHz (from an integrated oscillator) for cards power reduction mode
• Automatic activation and deactivation sequences through an independent sequencer
• Supports the asynchronous protocols T = 0 and T = 1 in accordance with ISO7816 and EMV
• Versatile 24-bit time-out counter for Answer To Reset (ATR) and waiting times processing
• Supports synchronous cards
• Specific Elementary Time Unit (ETU) counter for Block Guard Time (BGT)
• Current limitations on cards contacts and emergency deactivation in case of over consumption or overheating
• Special circuitry for killing spikes during power-on or power-off
• Supply supervisor for power-on or power-off reset
• High efficiency inductive DC-to-DC converter for VCC generation
• Soft switch on for avoiding current inrush at plug in
• Enhanced ESD protections on cards contacts (6 kV minimum)
• Software library for easy integration within the application.APPLICATIONS
• Smart card readers for PC’s or Set Top Boxes.
