Maximum ratings
2.1
Operating range
Within the operating range, the part operates as specified and without parameter deviations. The device may not
operate properly if the maximum operating conditions are exceeded.
Once taken beyond the operative ratings and returned back within, the part recovers with no damage or
degradation.
Additional supply voltage and temperature conditions are given separately at the beginning of each electrical
specification table.
All the voltages are related to the potential at substrate ground.
2.1.1
Supply voltage ranges
All SPI communication, logic, and oscillator parameters work down to VSREG = 3.5 V and are specified
accordingly.
•
SPI thresholds
•
Oscillator frequency (delay times correctly elapsed)
•
Internal register status correctly kept (reset at default values for VS < VPOR)
•
Reset threshold correctly detected
2.2
Absolute maximum ratings
Maximum ratings are absolute ratings; exceeding any one of these values may cause permanent damage to the
integrated circuit.
All voltages are related to the potential at substrate ground.
