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.
