I2C-bus SIM card interface
TDA8003TS
Protections
The following main hardware fault conditions are
monitored by the circuit:
Short circuits between VCC and other contacts
Card take-off during transaction
Supply drop-out.
When one of these problems is detected during a card
session, the security logic block pulls SIMERR to LOW, to
warn the microcontroller and initiates an automatic
deactivation of the contacts (see Fig.6).
I/O circuit
The Idle state is realized by both I/O and SIMI/O being
pulled HIGH (via a 10 k
pull-up resistor from I/O to VCC
and via a 20 k
pull-up resistor from SIMI/O to VDDI).
I/O is referenced to VCC and SIMI/O to VDDI, thus allowing
operation with VCC ≠ VDD ≠ VDDI.
When configuration bit I/OEN is logic 0, then I/O and
SIMI/O are independent, which allows parallelization of
several TDA8003TS with only one I/O line on the
microcontroller side (up to 4 different I2C-bus addresses).
When bit I/OEN is logic 1, then the data transmission
between I/O and SIMI/O is enabled.
The first side on which a falling edge occurs becomes the
master. An anti-latch circuit disables the detection of falling
edges on the other side, which becomes a slave.
After a delay time td (<500 ns) on the falling edge, the
N transistor on the slave side is turned on, thus
transmitting the logic 0 present on the master side.
When the master goes back to logic 1, the P transistor on
the slave side is turned on during td, and then both sides
return to their Idle states.
The maximum frequency on these lines is 1 MHz.
