AT49LV1024-90JC

Memory: AT49LV1024-90JC

The AT49LV1024-90JC is a type of integrated circuit (IC) particularly used in the field of memory. It is a 1M-bit (128K x 8) EEPROM or Electrically Erasable Programmable Read-Only Memory, which is a type of non-volatile memory. This type of IC is widely used for applications that require long-term data storage and retrieval.

Application Field

The AT49LV1024-90JC is widely used for applications that require a non-volatile storage solution. It can be used for applications such as firmware storage for embedded systems, data storage for consumer products, and program and data storage for measuring instruments. Furthermore, it can also be used in the medical field for patient data storage, as it is highly reliable and requires minimal maintenance.

Working Principle

The AT49LV1024-90JC is an 8-bit EEPROM with a serial interface. It consists of 8 pins and is capable of operating in both 3.3V and 5V power supply mode, with a read and write access time of 75ns, which makes it a highly efficient and reliable IC. The device is organized as 128K x 8, meaning that it consists of 512 pages of 256 bytes each. Whenever a write or erase operation is done, a temporary storage register holds the data until the new data is stored in the Non-Volatile Memory (NVM). This ensures that data stored in the NVM is always consistent and up to date. The AT49LV1024-90JC also has an Internal Soft Error Protection (ISEP) feature, which prevents data corruption by continuously monitoring the Non-Volatile Memory.

Conclusion

The AT49LV1024-90JC is a reliable 8-bit EEPROM IC with a serial interface, suitable for applications that require a long-term non-volatile data storage and retrieval solution. It operates on both 3.3V and 5V power supply mode and its Internal Soft Error Protection (ISEP) feature ensures that data stored in the NVM is always consistent and up to date. It is widely used for different applications such as firmware storage for embedded systems, data storage for consumer products, and program and data storage for measuring instruments, making it a highly efficient and reliable IC.
