64Kbit I²C EEPROM — 1 MHz bus, wide supply
The M24C64-DFDW6TP is a 64Kbit serial EEPROM from STMicroelectronics, organized as 8K × 8 bits and accessed over an I²C bus at up to 1 MHz clock frequency. The 450 ns access time and 5 ms write cycle time (word/page) set the timing budget for firmware read-modify-write sequences — a page write completes in 5 ms, after which the next I²C start condition is recognized.
Active lifecycle — no LTB risk
Supplied on Tape & Reel (TR) with a Cut Tape (CT) option, the packaging is pick-and-place ready for high-volume assembly lines without a feeder change.
