TDA8023

Low power IC card interface

Rev. 01 — 16 July 2007

Product data sheet

1. General description

The TDA8023 is a complete cost-efﬁcient, low-power analog interface for synchronous or

asynchronous smart cards. It can be placed between the card and the microcontroller with

very few external components to perform all supply, protection and control functions.

2. Features

I I²C-bus controlled IC card interface in TSSOP28

I Supply voltage from 2.7 V to 6.5 V

I Independant supply voltage V_DD(INTF)for interface signals with the microcontroller

I Shutdown input for very low power consumption when the part is not used

I Power reduction modes when the card is active

I DC-to-DC converter for V_CCgeneration (capacitive doubler, tripler, or inductive, or

follower automatically selected according to supply voltage and card voltage)

I 1 speciﬁc protected half duplex bidirectional buffered I/O line, with current limitation at

±15 mA, maximum frequency 1 MHz

I 2 auxiliary card I/O lines controlled by I²C-bus (C4 and C8)

I V_CCregulation: 5 V, 3 V or 1.8 V ± 8 %, I_CC< 55 mA, current spikes of 40 nAs up to

20 MHz, with controlled rise and fall times, ﬁltered overload detection approximately

80 mA, current limitation about 120 mA

I Thermal and short-circuit protections on all card contacts

I Automatic activation and deactivation sequences: initiated by software or by hardware

in the event of a short-circuit, card take-off, overheating, V_DDor V_DD(DCDC)drop-out

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

I 20 MHz clock input

I Clock generation for the card up to 10 MHz (CLKIN divided by 1, 2, 4 or 5) with

synchronous frequency changes; stop HIGH or LOW or free running 1 MHz in cards

Low-power mode; current limitation on pin CLK (C3)

I RST signal (C2) with current limitation at 20 mA, controlled by an embedded

programmable CLK pulse counter on asynchronous cards or by a register on

synchronous cards

I ISO 7816-3, GSM 11.11 and EMV 2000 (payment systems) compatibility

I Supply voltage supervisor for spike killing during power-on and emergency

deactivation at power-off: threshold internally ﬁxed or set via an external resistor

bridge; pulse width internally ﬁxed or set via an external capacitor

I Card presence input with 10 ms built-in debouncing system

I One interrupt signal INT
