The 10ms write cycle time per word or page is the latency to budget for when updating calibration tables or configuration blocks. ## Package and mounting — 8-SOIC surface mount The supplier device package is 8-SOIC, same as the case code. The footprint matches any generic SO-8 land pattern. That means Microchip continues to manufacture it with no announced last-time-buy or end-of-life notice. For a BOM line this is a low-risk part to qualify into production — no need to stockpile or search for a drop-in replacement. The ROHS3 compliance covers current EU and global RoHS requirements.","metaTitle":"Microchip 93C76-E/SN 8Kbit Microwire EEPROM, 2 MHz","metaDescription":"Microchip 93C76-E/SN 8Kbit serial EEPROM with Microwire interface, 2 MHz clock, 4.5V-5.5V supply, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tube","Technology":"EEPROM","Memory Size":"8Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"2 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Microwire","Voltage - Supply":"4.5V ~ 5.5V","Memory Organization":"1K x 8, 512 x 16","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-SOIC","Write Cycle Time - Word, Page":"10ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.24000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3466b68adf94a7b135f60b5bfb0e247c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory organization of 93C76-E/SN?","answer":"The 8Kbit array is configurable as 1K x 8 (byte-wide) or 512 x 16 (word-wide), selected by the ORG pin.

For a drop-in footprint match in 8-SOIC, the 93C56B-I/SN (2Kbit) and 93C46B-I/SN (1Kbit) are smaller-density siblings with the same 2 MHz clock and pinout — useful if the BOM can scale down. None are exact capacity equivalents; a true 8Kbit replacement would be another 93C76 variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/93C76-E-SN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/93C76-E-SN when reusing this data.
