ON Semiconductor LE25S20FD-AH EEPROM

The LE25S20FD-AH from ON Semiconductor is a high-performance, 2-Kbit serial EEPROM (Electrically Erasable Programmable Read-Only Memory) designed for a wide range of applications that require a reliable and durable non-volatile memory solution. This EEPROM device utilizes the industry-standard SPI (Serial Peripheral Interface) bus, ensuring compatibility with a broad array of microcontroller and microprocessor systems.

With its compact 8-pin SOP (Small Outline Package), the LE25S20FD-AH is ideal for space-constrained applications. It offers a flexible organization of 256 x 8 bits, allowing for efficient storage and retrieval of configuration parameters, calibration data, or small application logs. The device operates over a wide voltage range of 2.5V to 5.5V, making it suitable for both 3.3V and 5V systems, and is designed to perform reliably in harsh environments with an operating temperature range of -40°C to +85°C.

One of the key features of the LE25S20FD-AH EEPROM is its endurance. It is capable of withstanding up to 1 million write cycles and has a data retention period of over 100 years, ensuring the integrity and longevity of the data stored within. Additionally, the EEPROM supports a fast write cycle time of 5 ms, enabling quick updates to stored data without significant delays.

The device also includes write protection mechanisms, such as hardware and software write protect options, to prevent accidental overwrite or erasure of data. This is particularly important for mission-critical applications where data integrity is paramount. Furthermore, the LE25S20FD-AH supports a sequential read mode, which allows for efficient reading of the entire memory array with a single command, streamlining the data retrieval process.

In summary, the ON Semiconductor LE25S20FD-AH EEPROM is a robust and reliable memory solution that offers excellent endurance, data retention, and compatibility with SPI bus interfaces. Its features make it an ideal choice for applications in consumer electronics, industrial control systems, automotive electronics, and other fields requiring a dependable non-volatile memory storage option.
