Battery Voltage Conversion

The battery voltage conversion is dependent on the initial

battery voltage (1.5V or 3V).

For 1.5V battery, the equation is:

V = code*3.35mV + 860mV

LSB = 3.35mV

Offset = 860mV

For 3V battery:

V = code*6.32mV + 1.62V

LSB = 6.32mV

Offset = 1.62V

SPI Operation

Full and unlimited EEPROM access is possible through the SPI

interface. The primary function of the SPI interface is

production calibration and UID programming, but it can also

be used in application, where the ISO15693 interface cannot be

used.

Data on the D_IN pin is latched in on the falling edge of the

SCLK signal. Data on the D_OUT pin is shifted out on the falling

edge of the SCLK signal. The bytes are sent MSbit first.

The SPI communication is byte-oriented. It is composed of 3

fields of fixed length: Command field (1 byte), Address field (1

byte) and Data field (4 bytes).

The structure of the Command field is defined in the table

below.
