Working Principles

AT93C86AY6-10YH-1.8-T utilizes EEPROM technology, which is based on floating gate transistors. The chip stores data by trapping electric charge within these transistors. To write data, a high voltage is applied to the control gate, allowing electrons to tunnel through the insulating layer onto the floating gate. Erasing data involves removing the trapped charge from the floating gate using an electrical pulse. During read operations, the presence or absence of charge on the floating gate is detected, determining the stored data.

AT93C86AY6-10YH-1.8-T finds applications in various fields, including: 1. Automotive electronics: Used for storing vehicle configuration data and firmware updates. 2. Industrial control systems: Provides non-volatile memory for storing critical parameters and calibration data. 3. Medical devices: Stores patient information, device settings, and event logs. 4. Consumer electronics: Used in smart TVs, set-top boxes, and gaming consoles for firmware storage and system configuration. 5. Internet of Things (IoT): Enables data logging and configuration storage in IoT devices.
