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 independant sequencer
Supports asynchronous protocols T = 0 and T = 1 in
accordance with:
– ISO 7816 and EMV 3.1.1 (TDA8029HL/C1 and
TDA8029HL/C2)
– ISO 7816 and EMV 2000 (TDA8029HL/C2).
1 to 8 characters FIFO in reception mode
Parity error counter in reception mode and in
transmission mode with automatic retransmission

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, or be masked with specific customer code. For
details on software development and on available tools,
please refer to application notes “AN01009”and
“AN10134”for the TDA8029HL/C1. For standard
embedded software, please refer to application note
“AN10206” for the TDA8029HL/C2.
