HCS515
4.6 Power Supply Supervisor
Reliable operation of the HCS515 requires that the
contents of the EEPROM memory be protected against
erroneous writes. To ensure that erroneous writes do
not occur after supply voltage “brown-out” conditions,
the use of a proper power supply supervisor device is
imperative (Figure 4-11 and Figure 8-4).
