Key Features
- 512Kbit (64KB) I2C EEPROM with up to 1 MHz fast-mode clock for high-speed sequential data logging
- 1 million write/erase cycle endurance and 200-year data retention rating for reliable long-life storage
- 8-pin DIP-8 package with hardware address pins supporting up to 8 devices on a single 2-wire I2C bus
Applications
The 24FC512-I/P is widely used for storing calibration data, configuration parameters, and event logs in industrial sensors, medical monitors, and embedded control systems. Its 512Kbit capacity and 64-byte page write buffer make it suitable for data logging applications where the host MCU periodically writes blocks of measurement data via a 2-wire I2C bus. The through-hole DIP-8 package simplifies prototyping and maintenance in laboratory instruments and low-volume production boards.

Frequently Asked Questions
How much data can the 24FC512-I/P store, and how is it accessed?
The 24FC512-I/P stores 512Kbits (64KB) of non-volatile data accessed over a 2-wire I2C interface at up to 1 MHz. Byte and page write modes with a 64-byte page buffer allow efficient block writes, and sequential read operations can retrieve the full 64KB content without re-issuing an address command.
How long does the 24FC512-I/P retain data without power, and how many write cycles does it support?
The device is specified for a minimum data retention period of 200 years at 25°C and guarantees at least 1 million write/erase cycles per byte location, making it reliable for frequently updated configuration registers or event counters in industrial equipment operating over -40°C to +85°C.
Can multiple 24FC512-I/P devices share a single I2C bus in an embedded system?
Yes, up to 8 units can coexist on one I2C bus by setting the 3 hardware address pins (A0, A1, A2) to unique binary combinations, providing a total of 512KB addressable non-volatile storage from a single 2-wire bus pair running at 100 kHz or 1 MHz fast mode.
Why choose the through-hole DIP-8 24FC512-I/P over surface-mount SOIC variants for a prototype design?
The 8-pin DIP-8 package fits standard 0.1-inch breadboards and solderless prototyping boards directly, allowing engineers to evaluate 64KB I2C EEPROM functionality without specialised SMT soldering tools, then migrate to the equivalent SOIC-8 or TSSOP-8 variant for final PCB production without changing firmware.
