DESCRIPTION\nThe M62021 is a system IC that controls the memory backup function of SRAM and microcomputer (internal RAM). The IC outputs reset signals(RES/RES) to a microcomputer at power-down and power failure.It also shifts the power supply to RAM from main to backup,outputs a signal (CS) that invokes standby mode,and alters RAM to backup circuit mode.FEATURES\n?Built-in switch for selection between main power supply and backup power supply to RAM.\n?Small difference between input and output voltage (IOUT=80mA,VIN=5V)0.2V typ\n?Detection voltage (power supply monitor voltage)4.40V±0.2V\n?Chip select signal output(CS) TWo channels of reset outputs(RES/RES)\n?Power on reset circuit built-in\n?Delay time variable by an external capacitance connected to t pin\n?Facilitates to form backup function with a few number of omponentsAPPLICATION\nPower supply control systems for memory backup of microcomputer system and SRAM boards with built-in\nbackup function that require switching between external power supply and battery.
