The 5 ms write cycle time (word or page) is typical for this density class; the host must poll the acknowledge polling sequence or insert a delay after each write. ## Obsolete — sourcing through independent distribution The M24C32-WBN6P carries an Obsolete lifecycle status from STMicroelectronics. This means ST no longer manufactures the part in its original DIP-8 package variant. For new designs, ST recommends migrating to the M24C32-WMN6TP (SOIC-8) or other surface-mount alternatives in the same M24C32 family.","metaTitle":"M24C32-WBN6P STMicroelectronics 32Kbit I²C EEPROM, 450 ns","metaDescription":"STMicroelectronics M24C32-WBN6P 32Kbit I²C EEPROM, 2.5–5.5 V supply, 450 ns access time, 8-DIP through-hole, −40 to 85°C.","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":"450 ns","Memory Size":"32Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","Clock Frequency":"1 MHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2.5V ~ 5.5V","Base Product Number":"M24C32","Memory Organization":"4K 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/c68c8aacef617585487393340fdf138b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy M24C32-WBN6P?","answer":"The M24C32-WBN6P can be sourced through independent semiconductor distributors.
