TDA8029
Low power single card reader
s Minimum delay between two characters in reception mode:
x In protocol T = 0:
12 ETU (TDA8029HL/C1)
11.8 ETU (TDA8029HL/C2).
x In protocol T = 1:
11 ETU (TDA8029HL/C1)
10.8 ETU (TDA8029HL/C2).
s Supports synchronous cards which do not use C4/C8
s Current limitations on card contacts
s Supply supervisor for power-on/off reset and spikes killing
s DC-to-DC converter (supply voltage from 2.7 to 6 V), doubler, tripler or follower
according to V_CC and V_DD
s Shut-down input for very low power consumption
s Enhanced ESD protection on card contacts (6 kV minimum)
s Software library for easy integration
s Communication with the host through a standard full duplex serial link at
programmable baud rates
s One external interrupt input and four general purpose I/Os.
3. Applications
s Portable card readers
s General purpose card readers
s EMV compliant card readers.
