AT49BV040-12JI Memory

AT49BV040-12JI is a memory device from ATMEL Corporation, an established and reliable semiconductor manufacturer. It is a 4 megabit multiple-access non-volatile memory device, which can be used in a wide range of applications. The device works through one-time programmable (OTP) memory technology, which is a cost-effective, low-power and reliable method for storing data.

Application Field

AT49BV040-12JI is a versatile memory device that can be used in many applications, especially in the area of embedded systems. One example is in automotive electronic control units (ECUs), where the device is used to store data regarding a vehicle’s performance and current operating status. It is also used in consumer electronics, medical equipment, and other consumer products. The device is well-suited to these types of applications due to its low power consumption, high capacity, and the ability to access data in an organized and reliable manner. The device is also relatively inexpensive and easy to integrate into a system, making it a popular choice for many applications.

Working Principle

AT49BV040-12JI works on a one-time programmable (OTP) memory technology. In this type of memory, data is stored in non-volatile memory cells that can only be written to once. After the data is written to the cell, the cell becomes locked and the data remains even when power is removed from the device. This type of memory is used because it provides reliable and long-lasting data storage while also being relatively inexpensive. The device is organized into four 64 kilobyte blocks of memory. Each block can be accessed in multiple ways, including random read and write, byte-wide serial access, and sector-lock. These are handled through various command sets, as outlined in the device’s datasheet.

Conclusion

AT49BV040-12JI is a reliable, low-cost, and low-power memory device from ATMEL Corporation. It can be used in a wide range of applications, from automotive ECUs to consumer electronics, due to its many features and low power requirements. The device works on a one-time programmable (OTP) memory technology that can be accessed in multiple ways through various command sets.
