The device supports a 1 MHz clock rate with a 450 ns access time, suitable for storing configuration parameters, calibration data, or firmware lookup tables in embedded systems. ## Package and footprint considerations Housed in an 8-UFDFN with an exposed pad (2x3 mm body), this part is designed for surface-mount assembly on space-constrained PCBs. The supplier device package code is 8-UFDFPN (2x3). ## Write cycle and endurance Page and word write cycles complete in 5 ms typical. The EEPROM is rated for 1 million write cycles per byte and 40-year data retention at 85°C, per the M24C32 family datasheet. For applications requiring frequent updates, consider wear-leveling in firmware to spread writes across the 4K x 8 array. ## Lifecycle status — obsolete, no official successor The M24C32-FMB5TG is listed as obsolete by STMicroelectronics. No direct pin-compatible replacement has been designated by the manufacturer. For new designs or BOM continuity, a parametric cross to a current-production 32-Kbit I²C EEPROM in a similar 8-UFDFN package (e.g., the M24C32 series in a different ordering code or an alternate vendor) should be evaluated.","metaTitle":"STMicroelectronics M24C32-FMB5TG 32-Kbit I²C EEPROM, 1 MHz","metaDescription":"STMicroelectronics M24C32-FMB5TG 32-Kbit serial I²C EEPROM in 8-UFDFN package. 1 MHz clock, 450 ns access, 1.7 V to 5.5 V supply.
