Product Details

TDA8029 Low Power Single Card Reader

The TDA8029 series, from NXP, consists of complete one chip, low power, low cost, robust smart card readers. Its different power reduction modes and its wide supply voltage range allow its use in portable equipment. Due to specific versatile hardware, a small embedded software program allows the control of most cards available in the market. The control from the host may be done through a standard serial interface. The TDA8029 smart card reader has a 80C51 core with 16 kB ROM, 256 byte RAM and 512 byte XRAM. Suitable applications for the TDA8029 series include portable card readers, general purpose card readers and EMV compliant card readers. NXP’s software library also allows for easy integration.

Specific ISO7816 UART, accessible with MOVX instructions for automatic convention processing, variable baud rate, error management at character level for T = 0 and T = 1 protocols, extra guard time, etc.
Specific versatile 24-bit Elementary Time Unit (ETU) counter for timing processing during Answer To Reset (ATR) and for T = 1 protocol
VCC generation with controlled rise and fall times
Card clock generation up to 20 MHz with three times synchronous frequency doubling (fXTAL, 1⁄2fXTAL, 1⁄4fXTAL and 1⁄8fXTAL)
Card clock stop HIGH or LOW or 1.25 MHz from an integrated oscillator for card power reduction modes
Automatic activation and deactivation sequences through an independent sequencer
1 to 8 characters FIFO in reception mode
Parity error counter in reception mode and in transmission mode with automatic retransmission
Versatile 24-bit time-out counter for ATR and waiting times processing
Specific ETU counter for Block Guard Time (BGT) (22 ETU in T = 1 and 16 ETU in T = 0)
Supports synchronous cards which do not use C4/C8
Current limitations on card contacts
Supply supervisor for power-on/off reset and spikes killing
DC-to-DC converter (supply voltage from 2.7 to 6 V), doubler, tripler or follower according to VCC and VDD
Shut-down input for very low power consumption
Enhanced ESD protection on card contacts (6 kV minimum)
Communication with the host through a standard full duplex serial link at programmable baud rates
One external interrupt input and four general purpose I/Os.
