M62015L/FP, M62016L/FP Low Power 2 Output System Reset IC REJ03D0783-0100 Rev.1.00 Sep 14, 2005 Description The M62015 and 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 and M62016 carry out voltage detection in two steps and have two 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 Renesas microcomputer the M16C. Features • Bi-CMOS process realizes a configuration of low current dissipating circuits. Circuit current ICC = 3 µA (Typ, normal mode, VCC = 3.0 V) ICC = 1 µA (Typ, backup mode, VCC = 2.5 V) • Two-step detection of supply voltage Detection voltage in normal mode: VS = 2.7 V (Typ) Detection voltage in backup mode: VBATT = 2.0 V (Typ) • Two outputs Reset output (RESET): output of compulsive reset signal Interruption output (INT): output of interruption signal • Two types of output forms CMOS output: M62015L/FP open drain output: M62016L/FP Application • Prevention of errors in microcomputer system in electronic equipment that requires RAM backup, such as office, industrial, and home-use equipment.
