Nano-power highly accurate RTC with integrated quartz crystal

7.18 Safety notes

CAUTION

This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling

electrostatic sensitive devices.

Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or equivalent

standards.

8 Limiting values

Table 88. Limiting values

[1]

Pass level; Human Body Model (HBM) according to AEC Q100-002.

[2]

Pass level (750 V for corner pins); Charged-Device Model (CDM), according to AEC Q100-011.

[3]

Pass level; latch-up testing according to AEC Q100-004 at maximum ambient temperature (Tamb(max)).

[4]

According to the store and transport requirements (see [4]) the devices have to be stored at a temperature of +8 °C to +45 °C and a humidity of 25 % to

75 %.

Note: The PCF2131 part is not guaranteed (nor characterized) above the operating range as denoted in the

data sheet. NXP recommends not to bias the PCF2131 device during reflow (e.g. if utilizing a 'coin' type battery

in the assembly). If customer so chooses 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.
