MITSUBISHI M62015L,FP M62016L,FP LOW POWER 2 OUTPUT SYSTEM RESET IC DESCRIPTION PIN CONFIGURATION (TOP VIEW) 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. 5 4 3 2 1 VCC Cd RESET INT GND Outline 5P5T RESET 1 Cd 2 VCC 3 NC 4 INT GND NC NC 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 APPLICATION Prevention of malfunction of microcomputer systems in electronic, equipment such as OA equipment, industrial equipment, and homeuse electronic appliances. 8 7 6 5 Outline 8P2S-A NC : NO CONNECTION BLOCK DIAGRAM VCC R1 Com INTERRUPTION SIGNAL GENERATION BLOCK R2 INT R3 Com RESET SIGNAL GENERATION BLOCK RESET R4 GND (GROUND PIN) ( 1 / 3 ) Cd (PIN TO DELAY CAPACITANCE) MITSUBISHI M62015L,FP / M62016L,FP LOW POWER 2 OUTPUT SYSTEM RESET IC ABSOLUTE MAXIMUM RATINGS (Ta=25°C, unless otherwise noted.)
