M24C64S-FCU6T/TF

A: Thanks to its ultra‑small WLCSP‑4 footprint, wide operating voltage, industrial temperature range, and high reliability, the device is well‑suited for a broad range of applications including industrial control systems, consumer electronics such as smart appliances and wearable devices, medical devices requiring non‑volatile memory, and telecommunication systems [8†L37-L41][12†L29-L30]. ⚠️ Important Lifecycle Information: The lifecycle status of this part is conflicting. Some distributor databases list the M24C64S-FCU6T/TF as Obsolete or Discontinued, warning that the model is no longer in production [8†L10][9†L14][13†L2]. However, the related base part (M24C64S-FCU6T) is listed as ACTIVE on other distributor pages, and the product family page on the STMicroelectronics website remains available, suggesting the device is in production or available via recommended alternatives [14†L8]. Given this conflicting information, it is strongly recommended for new designs to verify current availability with an authorized STMicroelectronics distributor or to consider the M24C64X-FCU6T/TF as a suggested replacement [9†L23-L25].
