Philips Semiconductors Product specification
Smart card interface TDA8001
FEATURES
•Protected I/O line
•VCC regulation (5 V±5%, 100 mA max. with controlled
rise and fall times)
•VPP generation (12.5, 15or 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 “Application information”).
