Working Principles

The 93AA46BT-I/OT is based on EEPROM technology, which utilizes floating gate transistors to store digital information. When a voltage is applied, charges are trapped in the floating gate, altering the transistor's threshold voltage. This change can be detected during read operations, allowing the stored data to be retrieved.

Detailed Application Field Plans

The 93AA46BT-I/OT IC finds applications in various fields, including: 1. Consumer Electronics: Used in smart TVs, set-top boxes, and gaming consoles for storing configuration settings and user preferences. 2. Automotive: Employed in electronic control units (ECUs) for storing calibration data, fault codes, and vehicle-specific parameters. 3. Industrial Automation: Utilized in programmable logic controllers (PLCs) for storing program code, configuration data, and runtime variables. 4. Medical Devices: Integrated into medical equipment for storing patient data, device settings, and firmware updates.
