AT93C46R-10SC-1.8

The AT93C46R-10SC-1.8 belongs to the category of Electrically Erasable Programmable Read-Only Memory (EEPROM) and is typically used in various types of applications. This small EEPROM chip is available in an 8-pin PDIP package and is non-volatile, meaning that its content can be stored indefinitely, even with no power supply. As a result, it finds itself being used in products such as automotive airbag systems, radios, computers and peripheral devices, and smart cards.

In order to understand the working principle of the AT93C46R-10SC-1.8, it is essential to grasp the concept of EEPROM technology. Like other forms of memory, EEPROMs are composed of an array of cells. Each cell contains a single bit (1 or 0), and these cells are connected to respective read and write/erase transistors that enable data to be written onto and read from the memory. The key difference between EEPROMs and other types of memory lies in the way in which data can be written to and erased from the memory.

The AT93C46R-10SC-1.8 is capable of carrying out both single byte write and full page reads and writes. Individual bytes can be programmed and read freely while write access to multiple bytes is performed in a ‘page’ basis, i.e. a group of bytes that have the same data rate and address size. With only one command, multiple bytes of data can be written in the same page at the same time.

The AT93C46R-10SC-1.8 is most commonly used for applications for which frequently changing data is used, such as automotive airbag systems, where it is important to keep the data up to date and avoid data corruption due to power outages.It is also often used as a form of mapping memory in radios, computers and peripheral devices, as it enables consistent data mapping each time the device is powered on. The chip’s ability to be replaced at any given time allows it to be used as an upgradeable memory device in both industrial and consumer products.

In addition to its application fields, the chip is also used in smart cards where its non-volatile memory comes in handy. As the data held in the chip is not lost when the smart card is powered off, the AT93C46R-10SC-1.8 is perfect for applications such as access control cards, i.e. where the same code is required each time the card is presented.

In summary, the AT93C46R-10SC-1.8 is a versatile and reliable EEPROM chip that is used for a number of applications including automotive airbag systems, radios, computers and peripheral devices, and smart cards. It allows for both single byte write and full page reads and writes, and its non-volatile memory makes it very useful in applications where data needs to be kept consistently up-to-date.
