CAV24C02

The CAV24C02 is a low-power, serial EEPROM manufactured by onsemi, designed for reliable data storage in embedded systems. It features a 256-byte memory organization with 8-bit word length, offering efficient non-volatile storage for configuration settings, calibration data, or user-defined parameters. The device operates over a supply voltage range of 1.7V to 5.5V, making it suitable for both low-voltage and standard logic applications. Its CMOS technology ensures minimal power consumption, particularly in standby mode where current draw is typically less than 1 µA. This memory device supports the I²C-compatible two-wire interface, enabling simple integration into systems with limited pin count. The maximum clock frequency is 400 kHz, allowing fast read and write operations while maintaining compatibility with standard I²C bus protocols. Write protection is implemented via a hardware pin (WP), which can be tied to VCC or GND to enable or disable programming, enhancing system reliability during firmware updates or accidental writes. The CAV24C02 provides robust endurance with up to 1 million write cycles and data retention for up to 100 years at 25°C, ensuring long-term stability in industrial and consumer applications. Built-in write cycle protection and internal address auto-increment support simplify firmware design by reducing the need for complex memory management routines. Additionally, the device includes built-in error detection mechanisms such as write protect and address overflow checks, improving system integrity. Common applications include automotive electronics, consumer appliances, medical devices, and industrial control systems, where reliable, compact, and low-power memory solutions are essential. Its small 8-pin DIP and SOIC packages make it ideal for space-constrained designs, while its wide operating temperature range—from -40°C to +85°C—ensures performance in harsh environments. The CAV24C02 is also compliant with RoHS standards, supporting environmentally responsible manufacturing practices.
