TDA8003TS Datasheet, PDF (2/24 Pages) NXP Semiconductors – I2C-bus SIM card interface

Philips Semiconductors
I²C-bus SIM card interface
Product specification
TDA8003TS
FEATURES
• Subscriber Identification Module (SIM) card interface in
accordance with GSM11.11, GSM11.12 (Global System
for Mobile communication) and ISO 7816 requirements
• V_CC regulation (3 or 5 V ±8%) with controlled rise and
fall times
• Card take-off protection
• One protected and buffered pseudo-bidirectional I/O line
(I/O referenced to V_CC and SIMI/O referenced to V_DDI)
• Clock generation (up to 10 MHz) with synchronous start
and frequency doubling
• Clock stop LOW, clock stop HIGH or 1.25 MHz (from
internal oscillator) for cards Power-down mode
• Automatic activation and deactivation sequences of an
independent sequencer
• Automatic processing of pin RST with count of the CLK
cycles for start of the Answer To Reset (ATR)
• Warm reset command
• Supply voltage supervisor for Power-on reset, spike
killing and emergency deactivation in case of supply
drop-out
• DC-to-DC converter (doubler, tripler or follower)
allowing operation in a 3 or 5 V environment
(2.5 ≤ V_DD ≤ 6 V)
• Enhanced Electrostatic Discharge (ESD) protections on
card side (6 kV minimum)
• Power-down mode with several active features and
current reduction
• Off mode with 2 µA current
• Control from a microcontroller via a 400 kHz slave
I²C-bus (4 possible addresses: 48H, 4AH, 4CH
and 4EH)
• Four parallel devices possible due to 2 sub-address
wires
• Interface signals supplied by an independent voltage
(1.5 ≤ V_DDI ≤ 6 V).
APPLICATIONS
• GSM mobile phones
• SAM interfaces in banking terminals
• Portable card readers, etc.
GENERAL DESCRIPTION
The TDA8003TS is a low cost one chip SIM interface, in
accordance with GSM11.11, GSM11.12 and EMV96
(Europay, Mastercard, Visa) with card current limitation.
Controlled by I²C-bus, it is optimized in terms of board
space, external components count and connection count
(see Chapter “Application information”).
The integrated DC-to-DC converter ensures full
cross-compatibility between 3 or 5 V cards and 3 or 5 V
environments. The very low-power consumption in
Power-down mode and Off mode saves battery power.
