Communicating over I²C at up to 400kHz, they provide non-volatile byte-addressable storage for configuration data, calibration values, and data logging in embedded systems. With 3 hardware address pins (A0–A2), up to 8 devices can share the same I²C bus, providing up to 512KB of total EEPROM storage.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity\u003c\/td\u003e\n\u003ctd\u003e512Kbit (64KB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eI²C (up to 400kHz fast mode)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e2.5–5.5V (24LC512) \/ 1.7–5.5V (24FC512)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePage Size\u003c\/td\u003e\n\u003ctd\u003e128 bytes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWrite Cycle Time\u003c\/td\u003e\n\u003ctd\u003e5ms max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEndurance\u003c\/td\u003e\n\u003ctd\u003e1,000,000 erase\/write cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Retention\u003c\/td\u003e\n\u003ctd\u003e200 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAddress Pins\u003c\/td\u003e\n\u003ctd\u003eA0, A1, A2 (up to 8 devices on one bus)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eSOP-8 (SMD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e5 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhy Choose 24LC512?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e64KB capacity\u003c\/strong\u003e — largest single-chip I²C EEPROM in the 24-series, ideal for storing large config files and sensor logs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1M write cycle endurance\u003c\/strong\u003e — suitable for frequent data logging applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200-year data retention\u003c\/strong\u003e — reliable long-term non-volatile storage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 devices per bus\u003c\/strong\u003e — expandable to 512KB total via A0–A2 address pins\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.5–5.5V range\u003c\/strong\u003e — compatible with both 3.3V and 5V systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArduino\u003c\/strong\u003e: Wire library + 24LC512 library (I²C address 0x50–0x57)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eESP32 \/ ESP8266\u003c\/strong\u003e: Wire.h I²C at 3.3V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSTM32\u003c\/strong\u003e: HAL I²C driver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRaspberry Pi\u003c\/strong\u003e: smbus2 Python library\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammer tools\u003c\/strong\u003e: CH341A, T48, XGecu TL866II Plus (EEPROM mode)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eQ: What is the difference between 24LC512 and 24FC512?\u003c\/strong\u003e\u003cbr\u003eA: The 24FC512 supports a wider voltage range (1.7–5.5V vs 2.5–5.5V for 24LC512), making it suitable for 1.8V systems. Both are otherwise identical in capacity, speed, and pinout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: How do I set the I²C address on the 24LC512?\u003c\/strong\u003e\u003cbr\u003eA: Connect A0, A1, A2 pins to VCC or GND to set the 3-bit hardware address. The base I²C address is 0x50; with all pins to GND the address is 0x50, with all to VCC it is 0x57.

The 24LC512, AT24C512 (Atmel\/Microchip), and M95512 (ST) are functionally compatible with the same I²C protocol and pinout.
