The AT49BV4096A-12TC is a type of non-volatile memory (NVM) integrated circuit that has been widely used in electronic systems to store information, particularly in the automotive space. This IC is typically employed to store configuration data, software code, and other types of data, and is suitable for industrial solutions where low power consumption and durable data storage are required, such as safety-critical applications.

This NVM IC is available in a variety of capacities, including 4096 bits. It is one of the most popular ICs for non-volatile memory for such applications because of its simple programming technology and highly competitive price. It has a built-in capacitor to keep power supplied to the memory during a power loss, thus preventing accidental reset of the device and/or data loss.

The AT49BV4096A-12TC is divided into four blocks, each of which contain four pages of data. The data is divided into a program memory and a configuration memory, each of which can be programmed either by hardware or software configuration. There are four pins on the chip, which are dedicated to applying power, providing data and also controlling the reset condition.

The AT49BV4096A-12TC is available in a variety of package types, including PQFP, SOIC, SSOP and TSOP. Each package type offers an appropriate package size, power rating and other characteristics for various applications.

Application field of the AT49BV4096A-12TC is automotive, industrial, medical and consumer electronics. The semiconductor memory is used in a wide range of products, such as vehicle multimedia units, instrument clusters, global navigation systems, in-dash radios, satellite navigation receivers, sensors and audio systems.

The working principle of the AT49BV4096A-12TC IC is based on two main technologies, which include static memory cell (SMC) and static semiconductor non-volatile memory (SSNVM). SMC is a read-only memory that is used to store data permanently and can be accessed only if the device is powered up. SSNVM, on the other hand, is an electrically-programmable memory that can be programmed while the device is not powered up.

The AT49BV4096A-12TC IC uses a charge pump mechanism to provide the power for programming and erasing the memories. The charge pump is connected to the power supply to convert the power source from low voltage level to higher voltage. The pulses of the charge pump are used to activate the programming and erasing circuitry, which is embedded in the chip.

The AT49BV4096A-12TC provides an integrated solution for secure data storage and management in different types of applications such as automotive, industrial and consumer electronics. Its features include low power consumption, high endurance and reliability, fast programming speeds, and a wide temperature range. Additionally, the IC comes with an internal erase protection mechanism, which helps protect the data stored in the memory from accidental device reset and/or data loss.
