Description As applications for microcomputers are increasing, a desire has arisen for a RAM backup function. Let us introduce Renesas 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 realizes a configuration of low current dissipating circuits. ICC = 7 µA (Typ, normal mode, VCC1 = VCC2 = 5.0 V) ICC = 5 µA (Typ, backup mode, VCC1 = 5.0 V) ICC = 1 µA (Typ, backup mode, VCC1 = 2.5 V) • Two-step detection of supply voltage VCC1 (RESET): VS1-1 = 4.0 V (Typ, increase of VCC1) VS1-2 = 2.0 V (Typ, decrease of VCC1) VCC2 (INT): Free setup • 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) • Three types of outline packages 8-pin plastic SIP (single in-line package) 8-pin plastic DIP (dual in-line package) 8-pin plastic SOP (mini flat package) • Output based on RAM backup mode (see the timing chart) Application • Prevention of errors in microcomputer system in electronic equipment that requires RAM backup, such as office, industrial, and home-use equipment.
