M62021FP - System Reset-IC

Download the M62021FP datasheet PDF. This datasheet also covers the M62021L variant, as both devices belong to the same system reset-ic family and are provided as variant models within a single manufacturer datasheet.

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.

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.

M62021L/P/FP System Reset IC with Switch for Memory Backup REJ03D0784-0200 Rev.2.00 Jun 15, 2007 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. The M62021 contains, in a single chip, power supply monitor and RAM backup functions needed for a microcomputer system, so that the IC makes it possible to construct a system easily and with fewer components compared with a conventional case that uses individual ICs and discrete components.
