Description and Introduction

5.0, 3.3, OR 3.0V, 1280 Bit (160 X8) Secure Serial RTC and NVRAM Supervisor with Tamper Detection The M41ST87WMX6 is a serial real-time clock (RTC) manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
1. **Interface:** I²C (400 kHz)  
2. **Supply Voltage:** 2.7V to 5.5V  
3. **Timekeeping Current:** 400 nA (typical at 3V)  
4. **Clock Accuracy:** ±5 ppm (±0.432 seconds/day) from 0°C to +40°C  
5. **Operating Temperature Range:** -40°C to +85°C  
6. **Package:** 8-lead SOIC (150 mil)  

### **Descriptions:**  
- The M41ST87WMX6 is a low-power serial RTC with an integrated 32.768 kHz oscillator.  
- It provides timekeeping (seconds, minutes, hours, day, date, month, year) with leap-year compensation up to 2099.  
- Includes a watchdog timer and a programmable alarm.  
- Features a battery switchover circuit for backup power.  

### **Features:**  
- **Low Power Consumption:** Ultra-low standby current for battery-backed applications.  
- **Battery Backup:** Automatic switchover to a backup supply when primary power fails.  
- **Integrated Oscillator:** No external crystal tuning required.  
- **Alarm Function:** Programmable with interrupt capability.  
- **Watchdog Timer:** Configurable timeout period.  
- **Tamper Detection:** Optional feature for security applications.  
- **EEPROM:** 128 bytes of non-volatile memory for user data storage.  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

5.0, 3.3, OR 3.0V, 1280 Bit (160 X8) Secure Serial RTC and NVRAM Supervisor with Tamper Detection

Alternative Part Number

  • DS1307Z+ --: I2C real-time clock with 56-byte NV SRAM in an SOIC-8 package, functionally similar to the M41ST87W RTC plus supervisor role; widely available and pin-compatible in function for timekeeping applications.
  • PCF8563T --: Low-power I2C real-time clock/calendar in SOIC-8, offering comparable timekeeping and alarm functions as a cost-effective alternative when the integrated supervisor features are not strictly required.
  • BQ32000DR --: I2C real-time clock with integrated trickle-charge and backup switching in SOIC-8, providing similar battery-backed timekeeping functionality as an alternative RTC solution.
