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.
