Description and Introduction

64Kbit and 32Kbit Serial IC Bus EEPROM The M24C32-BN6 is a 32-Kbit serial I2C bus EEPROM manufactured by STMicroelectronics.  

### **Specifications:**  
- **Memory Size:** 32 Kbit (4 Kbyte)  
- **Interface:** I2C-compatible (2-wire)  
- **Operating Voltage:** 1.7V to 5.5V  
- **Write Cycle Time:** 5 ms (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Endurance:** 4 million write cycles  
- **Data Retention:** 200 years  
- **Package:** SO8 (150 mil width)  

### **Descriptions:**  
- The M24C32-BN6 is a non-volatile memory device that supports byte and page write operations.  
- It features a write-protect pin (WP) for hardware data protection.  
- It operates in a wide voltage range, making it suitable for various applications.  

### **Features:**  
- I2C serial interface (up to 1 MHz)  
- Random and sequential read modes  
- Software write protection (partial or full memory)  
- Page write buffer (32 bytes)  
- Low power consumption (standby current < 5 µA)  
- Industrial temperature range  

This device is commonly used in automotive, industrial, and consumer electronics for storing configuration data and parameters.

Application Scenarios & Design Considerations

64Kbit and 32Kbit Serial IC Bus EEPROM

Alternative Part Number

  • AT24C32C-PU --: Pin-compatible 32Kbit I2C EEPROM in DIP-8 with similar voltage range and timing, widely available and a common drop-in replacement.
  • CAT24C32LI-G --: 32Kbit I2C serial EEPROM in DIP-8 with compatible pinout and 1.8V-5.5V operation, suitable functional equivalent.
  • 24LC32A-I/P --: Industry-standard 32Kbit I2C EEPROM in DIP-8, same interface and memory organization, well-established alternative to the ST part.
  • CAT24C32WI-GT3 --: 32Kbit I2C serial EEPROM with matching pinout and protocol, low power CMOS process, suitable replacement when SOIC package is acceptable.
