Описание товара

The AT24C128 is Microchip's 128Kb (16KB) serial EEPROM with I²C interface, offering up to 400kHz Fast Mode operation across a wide supply voltage range of 1.8V to 5.5V. With an endurance of 1 million write cycles and 100-year data retention, it is one of the most reliable choices for embedded configuration storage.

In drone and autopilot applications, the AT24C128 stores flight controller configuration data, PID profiles, sensor calibration values, RC channel maps, and firmware startup parameters. It's also used for I²C address tables in distributed avionics systems.

AT24C Series Capacity Selection

  • AT24C02: 2Kb (256B) — minimal config, ID storage
