TDA8025

IC card interface

Rev. 01 — 6 April 2009

Product data sheet

1. General description

The TDA8025 is a cost-effective analog interface for asynchronous smart cards operating

at 3 V, 1.8 V or optionally, 1.2 V. Using few external components, the TDA8025 provides

integrated supply, protection and control functions for a range of applications.

2. Features

I Integrated circuit smart card interface

I 3 V, 1.8 V or 1.2 V smart card supply

I Low power consumption in inactive mode

I Three protected, half duplex, bidirectional buffered input/output lines (C4, C7 and C8)

I V_CCregulation:

N 3 V, 1.8 V or optionally 1.2 V at ± 5 % using one 220 nF and one 470 nF low ESR

multilayer ceramic capacitor.

N Current pulse handling for pulses of 40 nAs at V_CC= 3 V, 15 nAs at V_CC= 1.8 V or

V_CC= 1.2 V up to 20 MHz

I Thermal and short-circuit protection for all card contacts

I Automatic activation and deactivation sequences triggered by short-circuit, card

take-off, overheating, falling V_DD(INTF)and V_DD(INTREGD)

I Enhanced card-side ElectroStatic Discharge (ESD) protection of > 6 kV

I Clock signal using the internal oscillator or an external crystal (≤ 26 MHz) connected to

pin XTAL1

I Card clock generation up to 20 MHz with synchronous frequency changes of f_xtal

¹⁄₂f_xtal, ¹⁄₄f_xtalor ¹⁄₈f_xtalusing pins CLKDIV1 and CLKDIV2

I Non-inverted control of pin RST using pin RSTIN

I NDS certiﬁed

I Supply supervisors during power on and off:

N V_DD(INTREGD)using a ﬁxed threshold

N V_DD(INTF)using resistor bridge threshold adjustment

I Built-in debouncing on card presence contacts (typically 4.5 ms)

I Multiplexed status signal using pin OFFN

3. Applications

I Pay TV

I Electronic payment

I Identiﬁcation

I Bank card readers
