That is the period the internal charge pump needs to program the memory cells. During that time the I²C bus is held (no new commands accepted). For a design that writes calibration data at power-up, a 5 ms pause is invisible. For a datalogger that writes every few hundred milliseconds, budget the write time into the polling loop.","metaTitle":"M24C64-DFCT6TP/K STMicroelectronics EEPROM, 64Kbit I²C","metaDescription":"STMicroelectronics M24C64-DFCT6TP/K 64Kbit I²C EEPROM, 450 ns access, 1.7-5.5V supply, industrial temp -40 to 85°C.

The base product number is M24C64, and the specific variant -DFCT6TP/K is documented in the M24C64 series datasheet, which covers the I²C interface, write timing, and AC/DC characteristics."},{"question":"Is M24C64-DFCT6TP/K compatible with 5V logic?","answer":"Yes. The supply voltage range of 1.7V to 5.5V means the part operates directly on a 5V rail. The I²C bus pins are 5V-tolerant, so no level shifter is needed when interfacing with 5V microcontrollers or ASICs."},{"question":"What is the write endurance of M24C64?","answer":"The M24C64 series is rated for 1 million write cycles per byte and 40 years data retention at 85°C, per the STMicroelectronics datasheet. This is typical for the I²C EEPROM family."},{"question":"How do I solder M24C64-DFCT6TP/K (WLCSP package) correctly?","answer":"Use a hot-air rework station with a fine nozzle, set to 280-300°C with low air flow. Preheating the board to 100-120°C reduces thermal shock. The WLCSP has no leads — the solder balls are directly on the die pads. A stencil with 0.3 mm apertures and a reflow profile matching SAC305 solder paste works. After reflow, inspect under magnification for solder bridging or head-in-pillow defects."},{"question":"Where can I buy M24C64-DFCT6TP/K?","answer":"We source this part to order.
