Product speciï¬cation
TDA8001
FEATURES
⢠Protected I/O line
⢠VCC regulation (5 V ±5%, 100 mA max. with controlled
rise and fall times)
⢠VPP generation (12.5, 15 or 21 V ±2.5%, 50 mA max.,
with controlled rise and fall times) (only at TDA8001 and
TDA8001T)
⢠Clock generation (up to 10 MHz), with synchronous
frequency doubling
⢠Overload, thermal and card extraction protections
⢠Current limitation in case of short-circuit
⢠Idle mode and special circuitry for spikes killing during
powering on and off
⢠Two voltage supervisors (digital and analog supplies)
⢠Automatic activation and deactivation sequences
through an independent internal clock
⢠Enhanced ESD protections on card side (4 kV min.)
⢠Easy chaining for multiple card readers
⢠ISO 7816 compatibility.
APPLICATIONS
⢠Pay TV (multistandards conditional access system,
videoguard, newscript)
⢠Multi-application smart card readers (banking, vending
machine, electronic payment identification).
GENERAL DESCRIPTION
The TDA8001 is a complete, low-cost analog interface
which can be positioned between an asynchronous smart
card (ISO 7816) and a microcontroller. It is directly
compatible with the new Datacom chip verifier.
The complete supply, protection and control functions are
realized with only a few external components, making this
product very attractive for consumer applications
(see Chapter âApplication informationâ).
