The 450 ns access time and 5 ms write cycle are standard for this density class. The part is packaged in a 4-bump WLCSP (0.80 × 0.67 mm), making it a fit for space-constrained designs like wearable devices, wireless modules, and sensor nodes where board real estate is at a premium. ## Obsolete — what that means for sourcing The M24C32-FCU6TP/TF is listed as Obsolete. Date codes and traceability vary — each reel should be screened before it hits the line. If volume or long-term support is required, a pin-compatible alternative in the M24C32 family with the same WLCSP footprint may be available; that should be confirmed against the board's layout and supply rails. ## Package reality — WLCSP assembly considerations The PCB land pattern must match the ST-recommended footprint exactly; there is no room for a fan-out. The package is MSL 1 typically, but verify the bag date code before reflow.","metaTitle":"ST M24C32-FCU6TP/TF 32Kbit I2C EEPROM, 1 MHz, 4-WLCSP","metaDescription":"STMicroelectronics M24C32-FCU6TP/TF 32Kbit I2C EEPROM, 1 MHz, 450 ns access, 4-WLCSP (0.80x0.67 mm), 1.7-5.5 V, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"M24C32-FCU6TP/TF","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"EEPROM","Access Time":"450 ns","Memory Size":"32Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"4-XFBGA, WLCSP","Clock Frequency":"1 MHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"1.7V ~ 5.5V","Base Product Number":"M24C32","Memory Organization":"4K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"4-WLCSP (0.80x0.67)","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c68c8aacef617585487393340fdf138b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is there a pin-compatible alternative to the M24C32-FCU6TP/TF in the same family?","answer":"Other M24C32 variants in different packages (SOIC, TSSOP) exist within the STMicroelectronics family and share the same I²C protocol and 4K×8 organisation, but only an official cross-reference or second-source listing in the record constitutes a validated alternate.
