Signal description
Serial Clock (SCL)
This input signal is used to strobe all data in and out of the device. In applications where this
signal is used by slave devices to synchronize the bus to a slower clock, the bus master
must have an open drain output, and a pull-up resistor must be connected from Serial Clock
(SCL) to V
most applications, though, this method of synchronization is not employed, and so the pull-
up resistor is not necessary, provided that the bus master has a push-pull (rather than open
drain) output.
Serial Data (SDA)
This bidirectional signal is used to transfer data in or out of the device. It is an open drain
output that may be wire-OR’ed with other open drain or open collector signals on the bus. A
pull up resistor must be connected from Serial Data (SDA) to V
the value of the pull-up resistor can be calculated).
Chip Enable (E0, E1)
These input signals are used to set the value that is to be looked for on the two least
significant bits (b2, b1) of the 7-bit device select code. These inputs must be tied to V
V
floating), these inputs are read as low (0,0).

Antenna coil (AC0, AC1)
These inputs are used to connect the device to an external coil exclusively. It is advised to
not connect any other DC or AC path to AC0 and AC1 pads. When correctly tuned, the coil
is used to power and access the device using the ISO 15693 and ISO 18000-3 mode 1
protocols.
