DESCRIPTION
APPLICATIONS
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.
PACKAGE
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.
Portable smart card readers for protocol T = 0
GSM mobile phones.
