LOW POWER 2 OUTPUT SYSTEM RESET IC
DESCRIPTION
The M62015, M62016 are semiconductor integrated circuits whose
optimum use is for the detection of the rise and fall in the power
supply to a microcomputer system in order to reset or release the
microcomputer system.
The M62015, M62016 carry out voltage detection in 2 steps and
have 2 output pins. As Bi-CMOS process and low power dissipating
circuits are employed, they output optimum signals through each
output pin to a system that requires RAM backup.
These ICs also support the backup mode of Mitsubishi
microcomputer the M16C.
FEATURES
• Bi-CMOS process realizes a configuration of low current dissipating
circuits.
Circuit current
ICC=3µA (Typ. , normal mode, VCC=3.0V)
ICC=1µA (Typ. , backup mode, VCC=2.5V)
• Two-step detection of supply voltage
Detection voltage in normal mode VS=2.7V (Typ.)
Detection voltage in backup mode VBATT=2.0V (Typ.)
• Two outputs
Reset output (RESET) : Output of compulsive reset signal
Interruption output (INT) : Output of interruption signal
• Output forms
CMOS output : M62015
Open drain : M62016
