It stores calibration constants, serial numbers, or small lookup tables in industrial control, telecom, and sensor modules where the microcontroller has limited GPIO. The 2 MHz clock rate supports fast readout for power-up parameter loading without holding the host in reset. The supply range covers 1.8V, 3.3V, and 5V logic rails without a level shifter, simplifying BOM integration. The 5 ms write cycle time per word or page means the host must wait for the write-complete cycle; polling the READY/BUSY status via the data output pin avoids a fixed delay. Not specified for under-hood automotive (no AEC-Q100) or downhole environments; a wider-temperature sibling would be needed for those.","metaTitle":"Microchip AT93C56B-SSHM-B 2Kbit 3-Wire Serial EEPROM, 2 MHz","metaDescription":"Microchip AT93C56B-SSHM-B 2Kbit EEPROM, 3-wire serial interface, 2 MHz clock, 1.7V-5.5V supply, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Technology":"EEPROM","Memory Size":"2Kbit","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":"3-Wire Serial","Voltage - Supply":"1.7V ~ 5.5V","Memory Organization":"256 x 8, 128 x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3","priceTiers":[{"qty":1,"price":"$0.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/815a1edcae51d19bf596dbf60047c5c2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AT93C56B-SSHM-B/alternatives.json"},"ai":{"faq":[{"question":"Is the AT93C56B-SSHM-B a 3-wire serial EEPROM?","answer":"Yes, it uses a 3-wire serial interface (Microwire-compatible) with a 2 MHz clock, organized as 256 x 8 or 128 x 16 bits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AT93C56B-SSHM-B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AT93C56B-SSHM-B when reusing this data.
