M62007FP中文资料Low Power 2 Output System Reset IC Series数据手册Renesas规格书

描述 Description

The M62001 to M62008 are semiconductor integrated circuits whose optimum use is for the detection of the rise and fall in the power supply to a microcomputer system in order to reset or release the microcomputer system.
The M62001 to M62008 carry out voltage detection in two-steps and have two output pins. As Bi-CMOS process and low power dissipating circuits are employed, they output optimum signals through each output pin to a system that requires RAM backup. As output signals, interruption (INT) and compulsive reset (RESET) signals are available. The interruption signal (INT) is used to alter the microcomputer from normal mode to backup mode and vice versa. These output signals are classified into pulse type (M62001 to M62004) and hold type (M62005 to M62008).

特性 Features

• Bi-CMOS process realizes a configuration of low current dissipating circuits.
   Circuit current
      ICC = 5 µA (Typ, normal mode, VCC = 5.0 V)
      ICC = 1 µA (Typ, backup mode, VCC = 2.5 V)
• Two-step detection of supply voltage
   Detection voltage in normal mode (2 types)
      VS = 4.45 V/4.25 V (Typ)
   Detection voltage in backup mode
      VBATT = 2.15 V (Typ)
• Two outputs
   Reset output (RESET): output of compulsive reset signal
   Interruption output (INT): output of interruption signal
• Two types of output forms: CMOS and open drain
• Two types of interruption output (INT) signals
   Pulse type (M62001 to M62004)
   Hold type (M62005 to M62008)
• Two types of outline packages
   5-pin plastic SIP (single 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.
