TDA8029

Low power single card reader

Rev. 03 — 22 February 2005

Product data sheet

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, 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

“AN10206”

for the TDA8029HL/C2.
