M24M02-A125

The M24M02-A125 is a 2 Mbit serial EEPROM manufactured by STMicroelectronics, offering high reliability and low power consumption. It operates on a 1.8V to 5.5V supply voltage range, making it suitable for a wide variety of applications across different power environments. The device features a standard I²C-compatible interface with a maximum clock frequency of 400 kHz, enabling efficient communication with microcontrollers and other digital systems. This memory device includes 262,144 bytes of user memory organized in 32,768 pages of 8 bytes each. It supports both byte-write and page-write operations, allowing flexible data handling and improved write efficiency when programming multiple bytes at once. Write protection is implemented through hardware pins (WP) and software-based locking mechanisms, ensuring data integrity against accidental overwrites or unauthorized access. The M24M02-A125 offers robust endurance performance, with up to 1 million write cycles, and data retention of up to 200 years, making it ideal for long-term storage in demanding industrial and consumer applications. Its operating temperature range spans from -40°C to +85°C, supporting reliable operation under extreme environmental conditions. Additionally, the device includes built-in error detection and correction mechanisms to enhance data accuracy and system reliability. Common applications include smart meters, industrial sensors, automotive electronics, consumer devices such as audio equipment and appliances, and medical instrumentation. In these contexts, the M24M02-A125 provides non-volatile storage for configuration parameters, calibration data, firmware updates, and user settings—ensuring that critical information persists even during power loss. The package is available in a compact 8-pin SO8 format, which simplifies integration into space-constrained designs while maintaining excellent thermal and mechanical stability. With its low standby current (typically 1 µA) and active current consumption of less than 3 mA, it meets modern energy-efficient design standards, particularly important in battery-powered systems. STMicroelectronics also ensures compliance with RoHS and other environmental regulations, aligning with global sustainability goals.
