AT49LV040-90JC is a 4M nonvolatile Flash memory with a device storage capacity offering fast access time and microsecond write cycle. It is widely used in numerous applications that require a very high speed and robust engineer. This type of memory technology is most commonly seen in various analog-to-digital converters, automotive, medical, military, industrial, and graphic applications.

The AT49LV040-90JC memory is based on a floating gate random access memory (FRAM) design with an array of floating gates storing data. Each floating gate is separated from the control gates by a thin oxide layer. In order to write and read data, the control gate voltage is changed relative to the floating gate. When the control gate is at a higher voltage, the electrons move from the floating gate to the control gate, allowing the data to be written. When the voltage is at a lower level relative to the floating gate, the electrons move back allowing the data to be read. This type of operation makes it possible to store a high amount of data and allow the data to be quickly read and written.

The AT49LV040-90JC memory is able to achieve high speed write cycles with very low power consumption thanks to its advanced design. The device supports up to 6-volt supply voltage and 1.8 to 2.7V media operating voltage and can handle more than 70,000 program/erase cycles without significant wear. In addition, the memory can also withstand an extended temperature range of -40°C/ -40 to +105°C/-40 to +85°C.

The AT49LV040-90JC supports multiple programming algorithms, including software and hardware assisted programming. The software assisted programming algorithm is used for fast programming and erasing. The hardware assisted programming algorithm is used for reliable and accurate programming. The memory device also supports 3-state output logic, allowing the user to control the amount of current consumed during data input/output.

Due to its features and excellent performance, the AT49LV040-90JC is a perfect choice for applications that require fast data processing while still conforming to power consumption requirements. Common applications of the device include automotive, medical, military, industrial, and graphics applications. The memory is also often used in embedded systems due to its compatibility with 3.3V and lower voltage levels. It is also an ideal choice for analog to digital converters, security systems, digital video/audio streaming, and other applications that require high speed data programming and reading.
