ON Semiconductor CAT24WC16J-1.8 EEPROM

The CAT24WC16J-1.8 is a high-performance, serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from ON Semiconductor. This EEPROM offers a 16-Kb memory capacity, specifically designed to cater to a wide array of applications that require low-power and high endurance for data storage.

This particular EEPROM operates at a supply voltage range of 1.8V to 5.5V, making it suitable for battery-operated and handheld devices where power conservation is crucial. It features a 2-wire I²C serial interface which facilitates simple and efficient integration into most microcontroller-based systems. The I²C interface also supports a bus speed of up to 400 kHz, allowing for quick data transfer when needed.

The CAT24WC16J-1.8 is organized as 2048 words of 8 bits each, and the memory is accessed via a 16-bit address. The robust design of this EEPROM ensures data retention for up to 100 years and supports up to one million write cycles, ensuring the reliability and longevity of the data stored within.

Additional features of the CAT24WC16J-1.8 include a hardware write protection pin that can be used to prevent unintended writes to the memory array. This can be particularly useful in applications where data integrity is paramount. Furthermore, the device is designed with a self-timed write cycle with auto-clear, which simplifies the write operation and reduces the software overhead required to manage the write sequences.

The CAT24WC16J-1.8 comes in an 8-lead SOIC package, which is not only space-efficient but also widely accepted in the industry, making it easy to integrate into a variety of PCB designs. Its operational temperature range of -40°C to +85°C ensures that it can withstand harsh environments and maintain stable performance across a broad range of temperature conditions.

Whether it's for storing configuration settings, calibration data, or small amounts of information that need to be preserved between power cycles, the CAT24WC16J-1.8 from ON Semiconductor is a reliable choice for designers looking to enhance their systems with a durable and efficient non-volatile memory solution.
