AS39513 − Electrical Characteristics

Note(s):

1. Temperature 25°C, supply VBAT=3.3V from RF field unless noted otherwise

2. CMOS inputs CE and SCLK have 100k Ohm pull down resistor permanently connected. CMOS Input DIN can be configured with pull

up or pull down. See DIMD[1:0].

3. Below VBAT=1.35V operation and performance of AS39513 is not guaranteed.

4. Temperature sensor accuracy measured performance on wafer with gold bumped die measured at 3.0V for 3V trimmed devices and

1.5V for 1.5V trimmed devices. Assembly method can influence the temperature sensor accuracy.
