Description

24FC512T-E/OT is a 512-kbit serial I2C EEPROM. Key points:
- Memory: 64 kB (64,000+ bytes) organized as 64K x 8.
- Interface: 2‑wire I2C. Device address base 1010 plus A2–A0 pins; requires a 16‑bit address for the memory location.
- Features: byte/ page write (typical page size ~128 bytes), random and sequential reads, low-power modes.
- Performance: write cycle time typically a few milliseconds; endurance around 1,000,000 write cycles; data retention on the order of years.
- Power and temperature: operating voltage and exact range depend on variant; “E” denotes extended temperature (often -40°C to +85°C); packaging options denoted by “/OT” suffix.
- Applications: memory expansion for microcontrollers, configuration data, calibration and logging data.
Note: exact voltage range, package options, and device addressing can vary by manufacturer. Refer to the specific datasheet for the 24FC512T-E/OT you’re using to confirm voltage, temp range, page size, and pinout.
