Description and Introduction

3.3V-5V TIMEKEEPER Supervisor The **M48T201V-85MH1F** is a timekeeping SRAM (Static Random Access Memory) module manufactured by **STMicroelectronics (STM)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (STM)  
- **Type:** Timekeeping SRAM (Non-Volatile)  
- **Density:** 128Kb (16K x 8)  
- **Access Time:** 85ns  
- **Operating Voltage:** 4.5V to 5.5V  
- **Package:** 28-pin SOIC (MH)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Retention:** Minimum 10 years  
- **Battery Backup Voltage:** 2.5V to 3.5V  

### **Descriptions:**
- The **M48T201V-85MH1F** is a **non-volatile SRAM** with an integrated real-time clock (RTC).  
- It combines **SRAM and a timekeeping circuit**, ensuring data retention during power loss via an embedded lithium energy source.  
- The device is designed for applications requiring **battery-backed memory and timekeeping**, such as industrial systems, servers, and embedded controllers.  

### **Features:**
- **Integrated Real-Time Clock (RTC):**  
  - Counts seconds, minutes, hours, day, date, month, and year (including leap year correction).  
  - Binary or BCD time representation.  
- **Automatic Power-Fail Detection:**  
  - Switches to battery backup when primary power fails.  
- **Low Power Consumption:**  
  - Active current: 20mA (typical).  
  - Standby current (battery mode): 1µA (typical).  
- **Industrial-Grade Reliability:**  
  - Supports extended temperature range (-40°C to +85°C).  
- **28-Pin SOIC Package:**  
  - Surface-mount design for compact PCB integration.  

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