Remark: The PCF85063A part is not guaranteed (nor characterized) above the operating range as denoted in the datasheet. NXP recommends not to

bias the PCF85063A device during reflow (e.g. if utilizing a 'coin' type battery in the assembly). If customer so chooses to continue to use this assembly

method, there must be the allowance for a full \Q0 V' level Power supply \Qreset' to re-enable the device. Without a proper POR, the device may remain in

an indeterminate state.

Pass level; Human Body Model (HBM) according to [1].

[3]

Pass level; Charged-Device Model (CDM), according to [2].

[4]

Pass level; latch-up testing, according to [3] at maximum ambient temperature (Tamb(max)).

[5]

According to the store and transport requirements (see [10]) the devices have to be stored at a temperature of +8 °C to +45 °C and a humidity of 25 % to

75 %.
