Description and Introduction

Serial I2C bus RTC with battery switchover The M41T83ZMY6E is a serial real-time clock (RTC) manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Interface:** I2C (400 kHz)
- **Supply Voltage:** 1.3V to 4.4V (operating range)
- **Timekeeping Current:** 400nA (typical at 3V)
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** SO8 (8-pin Small Outline)
- **Clock Accuracy:** ±5 ppm (±0.432 seconds/day) from 0°C to +40°C
- **Backup Battery Support:** Yes (for timekeeping during main power loss)
- **Alarm Function:** Programmable alarm with interrupt output
- **Counters:** Seconds, minutes, hours, day, date, month, year (with leap year correction up to 2099)
- **32.768 kHz Crystal Support:** Integrated oscillator for external crystal

### **Descriptions:**
- The M41T83ZMY6E is a low-power serial RTC with a built-in 32.768 kHz oscillator.
- It provides accurate timekeeping with very low power consumption, making it suitable for battery-backed applications.
- The device includes an I2C interface for communication with microcontrollers or other systems.
- It supports battery backup switching for continuous operation during power loss.

### **Features:**
- **Ultra-Low Power Consumption:** 400nA typical timekeeping current.
- **Wide Voltage Range:** Operates from 1.3V to 4.4V.
- **Battery Backup:** Automatic switchover to battery when main power fails.
- **Programmable Alarm:** Configurable alarm with interrupt output.
- **Leap Year Compensation:** Valid up to 2099.
- **Industrial Temperature Range:** -40°C to +85°C.
- **Small Form Factor:** SO8 package for space-constrained designs.

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