The part comes in a 4-ball WLCSP measuring 0.85 x 0.85 mm, rated for -40°C to 85°C industrial temperature range. This is a non-volatile memory intended for parameter storage, calibration data, or small firmware patches in space-constrained embedded designs. At 1 MHz I²C, the 650 ns access time is the time from the address match to the first data bit being available on the bus. The 5 ms write cycle time per word or page is typical for EEPROM — firmware must poll the acknowledge polling or insert a delay after each write.","metaTitle":"STMicroelectronics M24C64T-FCU6T/TF EEPROM, 64Kbit I²C, 1 MHz, Obsolete","metaDescription":"ST M24C64T-FCU6T/TF 64Kbit I²C EEPROM, 650 ns access, 1 MHz clock, 4-WLCSP, -40 to 85°C.
