Microchip Technology AT24HC04B-PU EEPROM
The AT24HC04B-PU is a high-performance, 4-Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology. This integrated circuit is designed to provide a flexible, non-volatile storage solution for various applications, including but not limited to, consumer electronics, automotive, industrial, and medical devices.
With its I²C-compatible (2-wire) serial interface, the AT24HC04B-PU ensures easy integration into most microcontroller-based systems, facilitating high-speed data transfer with minimal pin count. The device supports a voltage range of 1.7V to 5.5V, making it versatile for both low-power and standard operations.
The EEPROM is organized as 512 x 8 bits, which can be accessed in a random fashion, allowing for byte-level read and write operations. This granular level of access provides developers with the flexibility to update configuration parameters or store application data efficiently. Additionally, the AT24HC04B-PU offers a write cycle time of 5 ms, enabling rapid updates to stored information.
A notable feature of this EEPROM is its built-in error correction code (ECC) functionality, which enhances the reliability of the data storage by detecting and correcting any single-bit errors. This is particularly important in critical applications where data integrity is paramount.
The device also includes a write protect pin that, when activated, prevents accidental overwrites to the memory, thereby safeguarding the stored data. Furthermore, the AT24HC04B-PU is capable of withstanding harsh environments and is rated for an extended temperature range of -40°C to +85°C.
Packaged in a PDIP (Plastic Dual In-line Package), the AT24HC04B-PU is designed for through-hole mounting, which is ideal for prototyping and applications where manual assembly or board repairs are required.
In summary, the AT24HC04B-PU from Microchip Technology is a robust, reliable, and easy-to-use EEPROM solution that provides designers with a secure way to store data in a wide range of electronic applications.
