Description and Introduction

General Purpose Timer, CMOS The ICM7555 is a CMOS timer IC manufactured by Renesas Electronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 2V to 18V  
- **Low Power Consumption:** Typically 60µA at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Timing Accuracy:** ±2% over temperature range  
- **Output Current (Sink/Source):** Up to 100mA  
- **Trigger Voltage:** 1/3 VCC  
- **Threshold Voltage:** 2/3 VCC  
- **Reset Voltage:** ≤ 0.4V  

### **Description:**
The ICM7555 is a low-power CMOS version of the classic 555 timer IC. It provides the same functionality as the standard 555 but with significantly reduced power consumption. It is designed for precision timing, pulse generation, and oscillator applications.

### **Features:**
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Wide Operating Voltage Range:** Compatible with both low and high-voltage circuits.  
- **High Output Drive Capability:** Can drive TTL or CMOS loads.  
- **Improved Temperature Stability:** Better performance under varying temperatures.  
- **Pin-Compatible with Standard 555:** Drop-in replacement for NE555/LM555.  
- **Low Trigger and Threshold Currents:** Reduces timing errors.  
- **ESD Protection:** Improved reliability.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

General Purpose Timer, CMOS

Alternative Part Number

  • TLC555CP --: Low-power CMOS 555 timer with similar supply range and pinout, widely available and a common drop-in replacement for the ICM7555.
  • LMC555CN --: CMOS 555 timer offering very low power consumption and direct functional compatibility with the ICM7555 in most timing circuits.
  • NE555P --: Classic bipolar 555 timer with identical pinout and function; acceptable when higher supply current is tolerable and CMOS low-power behavior is not critical.
  • TLC555 --: Low-power CMOS 555 timer with similar supply range and pinout, widely available and a common drop-in replacement for the ICM7555.
  • LMC555 --: CMOS 555 timer offering very low power consumption and compatible pin configuration, suitable for most ICM7555 applications.
  • NE555 --: Classic bipolar 555 timer with identical pinout and function; acceptable when higher supply current is tolerable and cost is a priority.
