OPERATING CONDITIONS (Cont’d)
12.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for VDD, fCPU, and TA.
Notes:
1. Data based on characterization results, tested in production for ROM devices only.
2. When VtPOR is faster than 100 µs/V, the Reset signal is released after a delay of max. 42µs after VDD crosses the
VIT+(LVD) threshold.
3. If the medium or low thresholds are selected, the detection may occur outside the specified operating voltage range.
Below 3.8V, device operation is not guaranteed.
