AT25040B
EEPROM memory with 4K-bit capacity in various packages
Manufacturer： ['atmel', 'microchip']
series introduction
The AT25040B Series is a robust line of serial EEPROM (Electrically Erasable Programmable Read-Only Memory) devices designed to meet the demands of modern electronic applications requiring reliable and efficient data storage. This series features a memory capacity of 4 Kbits, which is organized in a 512 x 8-bit configuration, making it ideal for various low-power applications where moderate data storage is necessary. The AT25040B employs a serial peripheral interface (SPI) for high-speed data transfer, achieving clock rates of up to 10 MHz, thereby facilitating rapid communication between the memory device and the microcontroller or processor.
One of the standout characteristics of the AT25040B Series is its low power consumption, which is paramount in battery-operated devices. During read operations, the current draw is minimal, while the standby mode ensures that power is conserved when the device is not actively in use. This makes the AT25040B particularly suitable for applications such as portable medical devices, consumer electronics, and smart metering systems, where energy efficiency is critical.
The design of the AT25040B incorporates a versatile and compact 8-pin package, allowing for easy integration into various circuit layouts. The device supports a wide operating voltage range of 2.5V to 5.5V, which provides flexibility in system design and compatibility with different logic levels. Additionally, it features a built-in write protection mechanism, enhancing data integrity and security by preventing accidental overwrites during critical operations.
Typical applications for the AT25040B Series include storing configuration settings, calibration data, and user preferences, making it a valuable component in automotive systems, industrial automation, and IoT devices. Its reliability and endurance are further exemplified by the ability to withstand up to 1 million write/erase cycles, ensuring long-term usability in demanding environments. Overall, the AT25040B Series stands as a dependable solution for engineers seeking an efficient, high-performance EEPROM for their data storage needs.
