AT24C32ESTUMT 32-Kbit I2C Serial EEPROM Memory (SOT23-5)

Ensure your critical configuration data is saved safely and reliably with the AT24C32ESTUMT serial EEPROM. While modern microcontrollers have built-in Flash memory, it degrades quickly if written to frequently. This dedicated EEPROM IC boasts an incredibly high endurance of over 1 million write cycles, making it the perfect solution for continuously saving dynamic data like PID profiles, VTX tables, sensor calibration offsets, or bind phrases in custom RC electronics.

With a storage capacity of 32-Kbits (4 KBytes), it provides ample space for most configuration files and small data logs. It communicates via a standard 2-wire I2C interface, meaning it can easily share the same data bus with your barometer or compass without requiring additional MCU pins. Housed in a microscopic 5-pin SOT23-5 package and supporting a wide voltage range of 1.7V to 5.5V, it is a highly versatile and space-saving addition to any custom flight controller or IoT sensor node.

Key Features:

• High Write Endurance: Rated for over 1,000,000 write cycles and 100 years of data retention, vastly outperforming standard microcontroller Flash memory for frequent data saving.

• I2C Interface: Utilizes a simple 2-wire bus (SDA/SCL) up to 400 kHz or 1 MHz, making it incredibly easy to integrate into existing sensor networks.

• Wide Voltage Range: Operates seamlessly from 1.7V up to 5.5V, ensuring direct compatibility with both 3.3V (STM32, ESP32) and 5V (Arduino) logic levels.

• Microscopic Footprint: The ultra-compact SOT23-5 package takes up virtually zero space on densely populated PCBs.
