Low-Power Single Card Reader | NXP Semiconductors

Overview

The TDA8029 is a complete one chip, low cost, low power, robust smart card reader. 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 many cards available in the market. The control from the host may be done through a standard serial interface.

The TDA8029 may be delivered with standard embedded software. For details on standard embedded software, please refer to “AN10206” for the TDA8029HL/C2.

Features

80C51 core with 16 kB ROM, 256-byte RAM and 512-byte XRAM
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
V_CC generation with controlled rise and fall times
Card clock generation up to 20 MHz with three times synchronous frequency doubling (f_XTAL, 1⁄2f_XTAL, 1⁄4f_XTAL and 1⁄8f_XTAL)
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
Supports asynchronous protocols T = 0 and T = 1 in accordance with:
- ISO 7816 and EMVCo4.3 (TDA8029HL/C2).
- for EMVCo4.3c support it is recommended to use PN7412AU as TDA8029 is not anymore compliant.
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)
Minimum delay between two characters in reception mode:
- In protocol T = 0:
  
  11.8 ETU (TDA8029HL/C2)
- In protocol T = 1:
  
  10.8 ETU (TDA8029HL/C2)
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 V_CC and V_DD
Shut-down input for very low power consumption
Enhanced ESD protection on card contacts (6 kV minimum)
Software library for easy integration
Communication with the host through a standard full duplex serial link at programmable baud rates
One external interrupt input and four general purposes I/Os

Target Applications

Portable card readers
General purpose card readers
EMV compliant card readers
