At 400 kHz I²C, that 900 ns leaves margin for the rest of the bus transaction. The M24C01-WBN6 is officially listed as obsolete by STMicroelectronics. ## Pin-compatible replacement planning The M24C01 family shares the same I²C interface, 1Kbit density, and 8-pin DIP footprint across density variants. For a new design or a BOM refresh, a current-production I²C EEPROM in the same 8-DIP package from ST or a second-source vendor would be the natural cross-shop — same pinout, same supply range, same bus speed.","metaTitle":"STMicroelectronics M24C01-WBN6 EEPROM, 1Kbit I²C 400kHz","metaDescription":"STMicroelectronics M24C01-WBN6 1Kbit serial I²C EEPROM, 400 kHz clock, 2.5V-5.5V supply, -40 to 85°C, 8-DIP through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Bulk","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"1Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2.5V ~ 5.5V","Base Product Number":"M24C01","Memory Organization":"128 x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-PDIP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0ebd86c753cbd45e05f6fa564548737f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for the M24C01-WBN6?","answer":"No official replacement order code is published by STMicroelectronics.
