For a repair bench or a production line that still carries this BOM position, the part is no longer manufactured — any new build or board repair relies on existing stock through independent distribution. ## Memory organization and interface It communicates over the I²C bus at up to 400 kHz — the standard two-wire interface that shares the bus with other I²C slaves, so the address pins (A0, A1, A2) must be pulled to VSS or VCC to set the device address on the bus. Access time is 900 ns; the write cycle time for a word or page is 5 ms. The page write mode lets you load up to 16 bytes into an internal buffer before the write cycle starts — useful for logging data in bursts without waiting per byte. Through-hole mounting means it sockets into a standard 8-pin DIP footprint — no hot-air rework needed, just a desoldering tool or a DIP socket for prototyping. The bulk packaging is loose tubes or trays, not tape-and-reel, so it ships as individual units for bench or low-volume assembly.","metaTitle":"STMicroelectronics M24C04-WBN6 EEPROM, 4Kbit, I²C, 8-PDIP","metaDescription":"STMicroelectronics M24C04-WBN6 4Kbit I²C EEPROM, 512x8 organization, 400 kHz clock, 2.5-5.5V supply, 8-PDIP through-hole, -40°C 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":"900 ns","Memory Size":"4Kbit","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":"M24C04","Memory Organization":"512 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38a813ed54df35f5b6cd248ba6b0a414.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C04-WBN6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to M24C04-WBN6 in this EEPROM family?","answer":"The M24C04 family includes other package variants (SO-8, TSSOP-8) with the same I²C interface and memory organization, but those are surface-mount — a board spin is required to change from the 8-PDIP footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/M24C04-WBN6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/M24C04-WBN6 when reusing this data.
