should be increased to the recommended operating voltage range (Note) within 3ms from the detection
of the releasing voltage of the power-on reset circuit. If the supply voltage does not reach the range, the
TMPM370 cannot operate properly.
The power-on reset circuit generates a reset when the power is turned on. When the supply voltage is
The power-on reset circuit consists of a reference voltage generation circuit, a comparator and a
The supply voltage divided by ladder resistor is compared with the voltage generated by the reference
When power supply voltage goes on, if the supply voltage is equal to or lower than the releasing voltage
When power supply voltage goes down, if the supply voltage is equal to or lower than the detecting
During the generation of power-on reset, the power-on counter circuit, the CPU and peripheral circuits
When the power-on reset cuicuit is activated without an external reset input signal, the supply voltage
RVDD5
(Note） When the supply voltage rises, until the supply voltage (at RVDD5 pin) reach the recommended operating
voltage range (4.5V through 5.5V) and 200μs passes by, the following condition should be satisfied; Port L (PL0
and PL1) is opened or the input voltage is within 0.5 volts.
