Philips Semiconductors
Low-power (3 V/5 V) smart card coupler
Preliminary specification
TDA8005A
FEATURES
Smart card supply (5 and 3 V ±5%, 20 mA maximum
with controlled rise and fall times)
Smart card clock generation (up to 8 MHz), with two
times synchronous frequency doubling
Clock STOP HIGH, clock STOP LOW or 1.25 MHz (from
internal oscillator) for cards power-down mode
Specific UART on I/O for automatic direct/inverse
convention settings and error management at
character level
Automatic activation and deactivation sequences
through an independent sequencer
Supports the protocol T = 0 in accordance with
ISO 7816 GSM11.11 requirements (Global System for
Mobile communication); approved for Final GSM11.11
Test Approval (FTA)
Several analog options are available for different
applications: doubler or tripler DC-to-DC converter, card
presence, active HIGH or LOW, threshold voltage
supervisor, etc.
Overloads and take-off protections
Current limitations in the event of short-circuit
Special circuitry for killing spikes during power-on or off
Supply supervisor
Step-up converter (supply voltage from 2.5 to 6 V)
Power-down and sleep mode for low power
consumption
Enhanced ElectroStatic Discharge (ESD) protections on
card side (6 kV minimum)
Control and communication through a standard RS232
full-duplex interface
Optional additional I/O ports for:
– keyboard
– LEDs
– display
– etc.
P80CL51 microcontroller core with 4-kbyte ROM and
256-byte RAM.
APPLICATIONS
Portable smart card readers for protocol T = 0
GSM mobile phones.
GENERAL DESCRIPTION
The TDA8005A is a low-cost card interface for portable
smart card readers. Controlled through a standard serial
interface, it takes care of all ISO 7816 and GSM11.11
requirements for both 5 and 3 V cards. It gives the card
and the set a very high level of security, due to its special
hardware against ESD, short-circuiting, power failure, etc.
Its integrated step-up converter allows operation within a
supply voltage range of 2.5 to 6 V.
The very low power consumption in power-down and sleep
modes saves battery power.
Development tools, application report and support
(hardware and software) are available.
