Description and Introduction

SERIAL 1K 128 x 8 EEPROM The ST24C01 is a 1-Kbit (128 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by STMicroelectronics.  

### **Specifications:**  
- **Memory Size:** 1 Kbit (128 bytes)  
- **Interface:** I²C (Inter-Integrated Circuit) compatible  
- **Operating Voltage:** 1.8V to 5.5V  
- **Write Cycle Time:** 5 ms (maximum)  
- **Data Retention:** 40 years (minimum)  
- **Endurance:** 1,000,000 write cycles  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SO8, TSSOP8, and others  

### **Descriptions:**  
- The ST24C01 is a low-power, byte-erasable EEPROM with a simple two-wire serial interface.  
- It supports random and sequential read modes.  
- Features write protection via a hardware pin (WP).  

### **Features:**  
- **I²C-Compatible Interface:** Supports standard (100 kHz) and fast (400 kHz) modes.  
- **Page Write Mode:** Allows writing up to 8 bytes in a single operation.  
- **Hardware Write Protection:** Prevents accidental writes when enabled.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **AEC-Q100 Qualified:** Suitable for automotive applications (specific variants).
