TDA8029 Low power single card reader Rev. 3.4 12 June 2018 Product data sheet COMPANY PUBLIC 1 General description 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 most 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 toAN10207 for the TDA8029HL/C2. 2 Features and benefits 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 generation with controlled rise and fall times see Section 11 CC Card clock generation up to 20 MHz with three times synchronous frequency doubling 1 1 1 (f , f , f and f ) XTAL 2 XTAL 4 XTAL 8 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).
