“H” level input voltage
“L” level input voltage
“L” level peak output current
“L” level average output current
“L” level total average current
Notes 1: System is in the reset state when the value is the detection voltage of the voltage drop detection circuit or less.
2: The voltage drop detection circuit is operating in the RAM back-up with the POF instruction (system enters into the reset state when the value is
VRST or less). In the RAM back-up mode with the POF2 instruction, the voltage drop detection circuit stops.
3: The average output current (IOH, IOL) is the average value during 100 ms.

Recommended operating
condition
It shows the electrical characteristics range of detected voltage
for voltage drop detection circuit.
System reset occurs when the supply voltage is under
the detected voltage for voltage drop detection circuit.
Note:
Recommended operating conditions 1(Ta = –20 °C to 85 °C, VDD = 2.7 to 5.5 V, unless otherwise noted)
