TDA8007BHL
Multiprotocol IC card interface
– in Protocol T = 0: 11.8 ETU
– in Protocol T = 1: 10.8 ETU
Supports synchronous cards
Current limitations in the event of short-circuit (pins I/O1, I/O2, VCC1, VCC2, RST1
and RST2)
Special circuitry for killing spikes during power-on/power-off
Supply supervisor for power-on/power-off reset
Step-up converter (supply voltage from 2.7 V to 6 V), doubler, tripler or follower
according to V
CC
and V
DD
Additional input/output pin allowing use of the ISO UART for another analog interface
(pin I/OAUX)
Additional interrupt pin allowing detection of level toggling on an external signal (pin
INTAUX)
Fast and efficient swapping between the three cards due to separate buffering of
parameters for each card
Chip select input allowing use of several devices in parallel and memory space paging
Enhanced ESD protections on card side (except C4x, C8x): 6 kV (min.)
Software library for easy integration within the application
Power-down mode for reducing current consumption when no activity.
3. Applications
Multiple smart card readers for multiprocessor applications (EMV banking, digital pay
TV and access control, etc.).
