Description and Introduction

512 Kbit (64 Bit x8) Serial Access RTC and NVRAM Supervisor The M41ST85YMH6 is a serial real-time clock (RTC) manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Timekeeping Current:** 400nA (typical at 3V)  
- **Interface:** I²C (400kHz)  
- **Package:** SOIC-8  

### **Descriptions:**  
- **Functionality:** Provides real-time clock/calendar with battery backup, alarm, and watchdog timer.  
- **Memory:** Includes 56 bytes of non-volatile RAM (NV SRAM).  
- **Accuracy:** ±5ppm (0.432s/day) at 25°C.  
- **Battery Backup:** Supports external battery or supercapacitor for timekeeping during power loss.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated applications.  
- **Automatic Leap Year Compensation:** Valid up to 2099.  
- **Programmable Alarm & Interrupt:** Supports minute, hour, or day/month alarms.  
- **Watchdog Timer:** Configurable timeout period (62.5ms to 31.25s).  
- **Power-Fail Detection:** Monitors VCC and switches to backup supply.  

This device is commonly used in embedded systems, industrial controls, and consumer electronics requiring accurate timekeeping.

Application Scenarios & Design Considerations

512 Kbit (64 Bit x8) Serial Access RTC and NVRAM Supervisor

Alternative Part Number

  • DS1307Z+ --: I2C real-time clock with 56-byte NV SRAM in an SOIC-8 package, functionally similar to the M41ST85Y RTC plus supervisor combination and widely available.
  • PCF8563T --: Low-power I2C real-time clock/calendar in SOIC-8, a common drop-in style alternative for RTC functions with different naming and proven availability.
  • BQ32000DR --: I2C real-time clock with integrated trickle charger in SOIC-8, offering comparable RTC functionality from a different vendor and series.
