M62021L規(guī)格書(shū)詳情
Description
The M62021 is a system IC that controls the memory backup function of 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
? Built-in switch for selection between main power supply and backup power supply to RAM.
? Small difference between input and output voltage (IOUT= 80 mA, VIN = 5 V) 0.2 V Typ
? Detection voltage (power supply monitor voltage) 4.40 V ±0.2 V
? Chip select signal output (CS)
? Two channels of reset outputs (RES/RES)
? Power on reset circuit built-in
? Delay time variable by an external capacitance connected to Ct pin
? Facilitates to form backup function with a few number of components
Application
? Power supply control systems for memory backup of microcomputer system and SRAM boards with built-in backup function that require switching between external power supply and battery.
