DescriptionAs 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. If the backup supply voltage of M62009 goes lower than the voltage required for backup,the reset output(RESET output)which is different from the INT output gives the reset signal (forced reset) to the microcomputer.The interruption signal from the INT output recovers the microcomputer from the backup mode. To recover from reset, RESET output is canceled when the specified interval of time (delay time) elapses after the signal is given from the INT output.
