CAV24C256

The CAV24C256 is a 256-Kbit serial EEPROM from onsemi, designed for reliable data storage in embedded systems. It features a two-wire interface (I²C-compatible) operating at up to 400 kHz, enabling efficient communication with microcontrollers and other digital devices. The device supports both read and write operations, with a page write size of 16 bytes, allowing optimized data handling for applications requiring frequent updates. This memory offers a robust endurance of 1 million write cycles and retains data for up to 100 years at 25°C, ensuring long-term reliability in demanding environments. It operates over a wide supply voltage range of 1.7 V to 5.5 V, making it suitable for low-power and high-voltage systems alike. The CAV24C256 also includes hardware write protection via a dedicated WP pin, which prevents accidental data corruption during normal operation or power fluctuations. With a compact 8-pin DIP or SO package, the CAV24C256 provides space-efficient integration into circuit boards. Its internal architecture includes a 32-byte page buffer that enhances write performance by reducing the time needed for individual byte writes. Additionally, the device supports multi-master capability, allowing multiple controllers to access the memory without conflict when properly managed through the I²C protocol. Common applications include industrial control systems, consumer electronics, automotive modules, and medical devices where non-volatile memory is essential for storing configuration settings, calibration data, or firmware updates. The CAV24C256’s low power consumption—typically 1 μA in standby mode—makes it ideal for battery-powered applications such as portable instruments and IoT sensors. The device is fully compliant with JEDEC standards and manufactured under strict quality control processes, ensuring consistent performance across temperature ranges from -40°C to +85°C. This makes it well-suited for harsh environments including automotive, industrial automation, and outdoor equipment. With its combination of speed, durability, and versatility, the CAV24C256 serves as a dependable memory solution for modern electronic designs requiring persistent, programmable storage.
