Description and Introduction

3V to 5.5V, IrDA Infrared Transceiver with Integrated RS-232 Interface The MAX3130CAI is a real-time clock (RTC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (MAXIM)  
- **Part Number:** MAX3130CAI  
- **Package:** 8-pin SOIC  
- **Interface:** I²C (2-wire serial)  
- **Supply Voltage Range:** 1.6V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Timekeeping Accuracy:** ±2ppm (±0.1728 seconds/day) from 0°C to +40°C  
- **Clock Frequency:** 32.768kHz  
- **Battery Backup Input:** Supports external battery or supercapacitor  
- **Alarms:** Two programmable time-of-day alarms  
- **Oscillator Compensation:** Automatic digital trimming  
- **Leap Year Compensation:** Valid up to 2100  
- **Low Power Consumption:** 400nA (typ) in timekeeping mode  

### **Descriptions:**  
The MAX3130CAI is a low-power, high-accuracy real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO). It provides precise timekeeping with I²C communication and supports battery backup for continuous operation during power loss.  

### **Features:**  
- **Battery Backup:** Maintains timekeeping during power loss.  
- **Digital Oscillator Trimming:** Adjusts for crystal frequency deviations.  
- **Two Time-of-Day Alarms:** Configurable interrupts.  
- **Programmable Square-Wave Output:** Adjustable frequencies (1Hz to 32.768kHz).  
- **Power-Fail Detection:** Monitors VCC and switches to backup supply.  
- **Small Form Factor:** 8-pin SOIC package.  
- **Wide Voltage Range:** Operates from 1.6V to 5.5V.  

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