Organized as 256 x 8 bits, it stores configuration parameters, calibration constants, or serial numbers in designs where every GPIO counts — think sensor modules, compact IoT nodes, or small-form-factor industrial controls. The single-wire bus runs at 100 kHz, which is slower than SPI or I2C but often fast enough for infrequent parameter updates. That same wide margin covers mixed-voltage systems where the MCU runs at 3.3 V but legacy peripherals still use 5 V.","metaTitle":"Microchip 11LC020-I/SN EEPROM, 2 Kbit Single-Wire, 8-SOIC","metaDescription":"Microchip 11LC020-I/SN 2 Kbit EEPROM with Single-Wire interface, 100 kHz, 2.5V-5.5V, -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":"100 kHz","lifecycle_stage":"eol_hot","Memory Interface":"Single Wire","Voltage - Supply":"2.5V ~ 5.5V","Memory Organization":"256 x 8","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/7e0bb80ac6f9ae234873f64c6baf4f4d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/11LC020-I%2FSN/alternatives.json"},"ai":{"faq":[{"question":"What is the interface of 11LC020-I/SN?","answer":"The 11LC020-I/SN uses a Single-Wire interface, requiring only one data line plus ground for read and write operations.
