It stores configuration parameters, calibration constants, and device identity data that must survive power cycles. The 1.7V to 5.5V supply range lets it operate on a 3.3V rail without a level shifter, and the 450 ns access time is adequate for most microcontroller polling loops. STMicroelectronics lists the M24C32M-FCU6T/TF as Obsolete. Housed in a 4-bump WLCSP (4-XFBGA, supplier device package 4-WLCSP), this part is surface-mount and intended for reflow assembly. The wafer-level package eliminates the lead frame, reducing footprint to roughly the die size — a space-saving choice for compact PCBs. ## Write-cycle timing and endurance considerations The write cycle time for a word or page is 5 ms typical. In a system that stores frequent updates — like runtime counters or fault logs — the 5 ms write latency must be factored into the firmware timing budget to avoid bus stalls.","metaTitle":"M24C32M-FCU6T/TF 32Kbit I²C EEPROM – Obsolete, Sourcing Info","metaDescription":"STMicroelectronics M24C32M-FCU6T/TF 32Kbit EEPROM, I²C 1 MHz, 4-WLCSP, -40°C to 85°C.
