7. POC CIRCUIT (MASK OPTION)
The POC circuit monitors the power supply voltage and applies an internal reset in the microcontroller at the
time of battery replacement. If the applied circuit satisfies the following conditions, the POC circuit can be
incorporated by the mask option.
High reliability is not required.
Clock frequency f
OSC
= 300 to 500 kHz
Power supply voltage V
DD
= 2.2 to 3.6 V
Operating ambient temperature T
A
= –20 to +70
°
C
Cautions 1. The one-time PROM product (
μ
PD66P04B) originally contains the POC circuit.
2. There are cases in which the POC circuit cannot detect a low power supply voltage of less
than 1 ms. Therefore, if the power supply voltage has become low for a period of less than
1 ms, the POC circuit may malfunction because it does not generate an internal reset signal.
3. If the applied circuit does not satisfy the conditions above, design the applied circuit in such
a manner that the reset takes effect without failure within the power supply voltage range
by means of an external reset circuit.
4. In order to prevent malfunction, be sure to input a low level to more than one of pins K
I0
to
K
I3
when reset is released (when RESET pin changes from low level to high level, or POC
is released due to supply voltage startup).
Remarks 1.
It is recommended that the POC circuit be incorporated when applied circuits are infrared remote-
control transmitters for consumer appliances.
2.
Even when a POC circuit is incorporated, the externally entered RESET input is valid with the OR
condition; therefore, the POC circuit and the RESET input can be used at the same time. However,
if the POC circuit detects a low power supply voltage, the RESET pin will be forced to low level;
therefore, use an N-ch open drain output or NPN open collector output for the external reset circuit.
