Memory is an important component in computer systems, providing access to data within computers and other mobile devices. The 93AA46B-I/SN is a non-volatile memory device from Microchip Technology, and it’s widely used in various applications. This article is going to take a look at the application field and working principle of the 93AA46B-I/SN.

The 93AA46B-I/SN is a 64-bit I2C 2-Wire Serial EEPROM with a 1.75V – 5.5V supply voltage and an interface speed of up to 400kHz. The device consists of an array of 4K bits organized as 512 bytes and it\'s packaged in an 8-pin SOIC (Small Outline Integrated Circuit). Besides that, it also includes an E2PROM burst read and serial sequence write, a built-in address counter and a data protection feature.

The 93AA46B-I/SN is mainly used in consumer electronics, audio applications and a variety of automotive, industrial and medical control applications. It’s suitable for a wide variety of applications including asset tracking systems, consumer product identification, car keyfob programming, program storage for instrumentation, configuration storage for intelligent lighting, and many more.

The working principle of the 93AA46B-I/SN is similar to other E2PROMs. It uses Fowler-Nordheim tunneling to write data. This process involves the injection of charge carriers into the gate oxide of a transistor to change the conductivity of the gate. The device then stores the data in a floating- gate structure which isolates the injected charge from the surrounding environment, and thus retains the stored data.

To read the data stored by the 93AA46B-I/SN, the device uses Fowler-Nordheim tunneling to deplete the stored charge. This process is similar to the write process, except that the charge carriers are removed instead of injected. The device then outputs the stored data to the user.

In conclusion, the 93AA46B-I/SN is an I2C 2-Wire Serial EEPROM from Microchip Technology and it is used for a wide range of consumer electronics, audio applications and automotive, industrial and medical control applications. Its working principle relies on Fowler-Nordheim tunneling to write and read data from its array of 4K bits organized as 512 bytes, and it uses a 1.75V – 5.5V supply voltage and an interface speed of up to 400kHz.
