General Description

As applications for microcomputers are increasing,a desire has arisen for a RAM backup function.Let us introduce Mitsubishi Electric new low power dissipation,high-performance system reset IC,which is suitable for such RAM backup.

The M62009,which is a low power-dissipation 2-output microcomputer system reset IC,is a 2-output system reset IC which provides for RAM backup in microcomputers,and reduces power dissipation by using the Bi-CMOS process.The M62009 considerably reduces the number of components in the reset circuit.

The M62009 performs two-stage detection of normal supply voltage and backup supply voltage required for backup mode.When the supply voltage is switched from normal supply voltage to back up supply voltage the interruption output,which is one of the two outputs,gives the interruption signal to a microcomputer,in this way,the microcomputer reduces power dissipation and enters in the backup mode.

Overview

MITSUBISHI<Dig.Ana.INTERFACE> M62009L,P,FP LOW POWER 2 OUTPUT SYSTEM RESET IC WITH EXTERNAL.

Key Features

  • Bi-CMOS process low power dissipation circuit configuration Icc=7µA(Typ. ) (Normal mode Vcc1=Vcc2=5.0V) Icc=5µA(Typ. ) (Backup mode Vcc1=5.0V) Icc=1µA(Typ. ) (Backup mode Vcc1=2.5V).
  • Two supply detection Vcc1(RESET) Vcc1-1=4.0V(typ):Increase of Vcc1 Vs1-2=2.0V(typ):Decrease of Vcc1 Vcc2(INT) Free set up.
  • Two outputs(open drain type) Reset output (RESET):Forced reset signal output Interruption output(INT):Output of the signal for interruption processing (output of the switch.
