Question:
Power-on clear in S-93CxxA, S-29xxxA, notes for power-on (malfunction)
Answer:
1.
This IC series has a built-in power-on clear circuit.
This circuit instantly initializes the EEPROM when the power voltage is activated. Since malfunction
may occur if initialization has not been completed normally, the conditions specified below are
required to activate the power voltage in order to operate the power-on clear circuit normally.
2.
Notes on power-on
Method for activating the power voltage
As shown in Fig. 1, activate the power voltage starting from a maximum of 0.2 V so that the power
voltage reaches the operating value within the time specified as tRISE. If the operating power
voltage is, for example, 5.0 V, tRISE = 200 ms, as shown in Fig. 2. Thus, the power voltage must be
activated within 200 ms.
