– LEDs
– display
– etc.
80CL51 microcontroller core with 4 kbytes ROM and
256-byte RAM.
APPLICATIONS
Portable smart card readers for protocol T = 0
GSM mobile phones.
GENERAL DESCRIPTION
The TDA8005 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. 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. A special version where
the internal connections to the controller are fed outside
through pins allows easy development and evaluation,
together with a standard 80CL51 microcontroller.
Development tools, application report and support
(hardware and software) are available.
The device can be supplied either as a masked chip with
standard software handling all communication between
smart card and a master controller in order to make the
application easier, or as a maskable device.
