Appl ic ation s

SPI Communication

Figure 30 shows an application using the SPI interface to

communicate with other circuitries.

The Serial Peripheral Interface (SPI) port can be connected to

external circuitries for display etc.; this allows further

communication between the chip and other circuits such as a

wireless transceiver for remote direct access to the logging data

and for easy setting of parameters and functions. The chip

supports an alarm system and functions that calculate shelf life.

Such applications are possible in both passive and semi-passive

mode. In passive mode, the chip provides a supply current of

maximum 4 mA from the VEXT assuming a reader provides

sufficient power from its field. The VEXT voltage is limited at 3.4V.
