93AA46/P

The 93AA46/P is a low power serial EEPROM (Electrically Erasable Programmable Read-Only Memory) with electrical characteristics that make it perfect for applications that require data to be stored and retrieved in a very small package.

Application Field

The 93AA46/P is designed for applications with long-term data retention requirements. It is commonly used in applications such as automotive and engine control systems, smart cards and phone cards, home security systems, barcode scanners, and other embedded systems.

In automotive and engine control systems, the 93AA46/P is utilized to store information such as engine and brake control parameters, and it can be used to enable a variety of diagnostic functions. In addition, it can be used to store customer information such as miles traveled, oil change mileage, and other service records.

The 93AA46/P is also often used in smart card and phone card systems to store customer information such as account numbers, access codes, and other data. It can also be used for encryption and authentication. In addition, it is ideal for storing owner information in home security systems and barcode scanner systems.

Working Principle

The 93AA46/P works by storing data into its non-volatile memory. This enables it to retain data even if power to the device is removed. The 93AA46/P incorporates an internal clock, which allows the device to self-time the accessing of its internal registers. It also has a 16-bit data register and an 8-bit address register for accessing its internal memory. Data can be written to or read from its internal memory using the same serial communication interface.

When a data write command is written to the device, the 93AA46/P will first check the status of its internal oscillator. If the oscillator is running, the device will then validate the write command and carry out the write operation on the internal memory. The device also incorporates a write protect feature that allows the user to lock the internal memory for writing.

When a data read command is sent to the device, the 93AA46/P will first check the status of its internal oscillator. If the oscillator is running, the device will then validate the read command and check the data in the internal memory. If the data matches, then the data will be read back in the form of a response byte.

The 93AA46/P is a very reliable and low power device which makes it the ideal solution for applications that require non-volatile, long-term data storage and retrieval.
