Frequently Asked Questions
How much storage does the 24C65-I/P provide, and at what I2C clock speed does it operate?
The 24C65-I/P provides 64 Kbits (8 KB) of non-volatile EEPROM storage accessed over a 2-wire I2C bus at up to 400 kHz in fast mode. This combination of 8 KB capacity and 400 kHz bus speed suits applications storing calibration tables, configuration blocks, or event logs in embedded microcontroller systems.
What write endurance and data retention does the 24C65-I/P guarantee for long-term data reliability?
The 24C65-I/P is rated for a minimum of 1,000,000 write/erase cycles per memory location, and offers a minimum 200-year data retention time. These specifications make it suitable for applications with frequent EEPROM updates such as runtime counters, dynamic calibration records, and system event logs that must persist reliably across the product lifetime.
What supply voltage range does the 24C65-I/P require, and which legacy systems is it best matched to?
The 24C65-I/P operates from 4.5 V to 6 V, making it ideal for 5 V digital systems — including older 8-bit microcontroller platforms, PLC I/O modules, industrial sensor nodes, and laboratory instruments — where 3.3 V EEPROM variants would require level shifting. This direct 5 V compatibility simplifies circuit design in legacy and through-hole board environments.
Why choose the 24C65-I/P in PDIP package for embedded development instead of surface mount alternatives?
The 8-pin PDIP package of the 24C65-I/P allows direct insertion into breadboards, DIP sockets, and through-hole PCBs without soldering, making it the preferred choice for rapid prototyping, educational lab setups, field-replaceable memory modules, and low-volume production where SMT rework equipment is not available. It also simplifies inspection and manual replacement in field-serviceable industrial equipment.
