Housed in an 8-pin PDIP (0.300-inch, 7.62 mm pitch) through-hole package, this part fits sockets and solder-in applications where board rework or prototyping access matters — the DIP body is still common in industrial control cards, test fixtures, and retrofit designs that avoid SMT. ## Timing and write-cycle budget Read access time is 450 ns — this is the time from the I²C slave address acknowledge to the first data byte appearing on SDA. For a 1 MHz bus (1 µs bit period), the access fits within one clock cycle, so the bus master does not need to insert wait states between the address and the read data. A firmware update writing 64 bytes per page across the full 64 Kbit array takes roughly 640 ms of bus time for the write cycles alone, not counting the address overhead. Budget this into the field-update window — the part does not acknowledge the I²C master during the internal write cycle. STMicroelectronics has marked the M24C64-WBN6P as Obsolete. No pin-compatible direct replacement is documented by ST; a functional equivalent would require verifying the I²C slave address, page size, and write-cycle timing against the replacement device.","metaTitle":"STMicroelectronics M24C64-WBN6P EEPROM, 64 Kbit, I²C, PDIP-8","metaDescription":"STMicroelectronics M24C64-WBN6P 64 Kbit serial EEPROM, I²C interface, 1 MHz clock, 2.5-5.5 V supply, industrial temp, PDIP-8.","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":"64Kbit","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":"M24C64","Memory Organization":"8K 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":"$0.2900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f80a2f163f84bd6e64a778a5e4f1c6d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C64-WBN6P/alternatives.json"},"ai":{"faq":[{"question":"What package does the M24C64-WBN6P come in?","answer":"It is supplied in an 8-pin PDIP (0.300-inch, 7.62 mm pitch) through-hole package, designated as 8-PDIP or 8-DIP by the supplier device package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/M24C64-WBN6P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/M24C64-WBN6P when reusing this data.
