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. 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 switching signal for backup mode) • Packages 2 types 5-pin SIP (single in-line) 8-pin SOP (mini flat) APPLICATION Prevention of errors in microcomputer system in electronic equipment that requires RAM backup,such as office,industrial,and home-use equipment.
