[1] When writing to the OTP cells, the supply voltage (V_DD) can be raised to a maximum of 12 V for a period of
1 s.
[2] Connecting the battery with reversed polarity does not destroy the circuit, but in this condition a large
current flows, which rapidly discharges the battery.
[3] Pass level; Human Body Model (HBM), according to Ref. 4 “JESD22-A114”.
[4] Pass level; Machine Model (MM), according to Ref. 5 “JESD22-A115”.
[5] Pass level; latch-up testing according to Ref. 6 “JESD78” at maximum ambient temperature (T_amb(max)).
[6] According to the NXP store and transport requirements (see Ref. 8 “NX3-00092”) the devices have to be
stored at a temperature of +8 °C to +45 °C and a humidity of 25 % to 75 %. For long term storage products
deviant conditions are described in that document.
