Memory is essential in any computing system. The AT93C46E-TH-T is one type of memory chip that can be used in a wide range of applications. This article will discuss the application field and working principle of the AT93C46E-TH-T.

AT93C46E-TH-T is an electrically erasable programmable read-only memory (EEPROM), 16384-bit serial EEPROM, which features a 4-wire serial interface, a 256-member repeated 1024-bit array and several write protection modes. It is typically used in automotive, Smart card, industrial, and medical applications. The device has a wide temperature range from -40°C to +85°C and can be used in harsh environments.

The AT93C46E-TH-T utilizes one of two communication protocols. The device uses either a 3-wire (select plus SPI) or a 4-wire interface. The SPI protocol has a maximum clock frequency of 200 kHz while the select plus SPI protocol has a maximum clock frequency of 1 MHz. The device also has a self-timed write cycle of 10 ms maximum.

The working principle of the AT93C46E-TH-T is based on a modified floating gate technology. A single floating gate is connected to a transistor. When an electrical signal is applied to the floating gate, the transistor is activated and the information stored on the floating gate is read. The whole process is non-volatile, which means that the information is not lost even when the power is turned off.

The AT93C46E-TH-T is a very versatile EEPROM memory device that can be used for a wide range of applications. In automotive applications, the device is used for vehicle identification, diagnostics, security, and airbag systems. In industrial applications, the device is used for digital signal processing, instrumentation control, and factory automation. In medical applications, the device is used for patient monitoring, medical imaging, and drug delivery.

The AT93C46E-TH-T is a reliable and efficient memory storage device that is suitable for a variety of applications. Its 4-wire interface allows for easy connection with other electronic components and its wide temperature range makes it suitable for harsh industrial environments.
