VCC-0.2
+0.025 (ms)
Vscpu
CL : F
RL : k
Vs cpu :
Reset threshold voltage of
CPU, MPU, etc.
Voltage: V
Note: Connect a capacitor between IC pins 1 and 2
if VCC line impedance is high.
[]
2. Manual reset added
Note 1: Use RL, CL and Rm to prevent manual switch
chattering.
Note that Rm should be set to the following
conditions.
Rm <
= 1/20RL
Note 2: Connect a capacitor between IC pins 1 and 2
if VCC line impedance is high.
3. Battery checker (LED ON for high voltage)
Note: Connect a capacitor between IC pins 1 and 2 if
VCC line impedance is high.
