This frees up GPIO on microcontrollers where every pin counts — think sensor calibration storage, configuration registers in a motor drive, or parameter logging in a field instrument. ## What the 100 kHz clock and 5 ms write cycle mean for your BOM The 100 kHz clock rate is modest — fine for infrequent reads like loading configuration at boot or logging a fault code. The 5 ms write cycle per word or page means a full 256-byte array rewrite takes about 1.3 seconds worst-case. That is acceptable for non-volatile parameter storage updated once per power cycle, but not for streaming data logging. The 256 x 8 organization (2Kbit) is sized for a few dozen calibration constants or a serial number block. ## Package and footprint: 8-TDFN (2x3 mm) The 8-WFDFN exposed pad package (supplier device package 8-TDFN, 2x3 mm) is a small, low-profile surface-mount package suited for dense PCBs. Microchip lists the 11LC020T-I/MNY as Active product status. For a BOM line this means no last-time-buy pressure and normal lead times through distribution. The part is ROHS3 compliant.","metaTitle":"Microchip 11LC020T-I/MNY 2Kbit EEPROM, Single Wire, 8-TDFN","metaDescription":"Microchip 11LC020T-I/MNY 2Kbit EEPROM with Single Wire interface, 2.5V-5.5V, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","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-TDFN (2x3)","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.32","priceTiers":[{"qty":1,"price":"$0.32000","currency":"USD"},{"qty":25,"price":"$0.31000","currency":"USD"},{"qty":100,"price":"$0.28000","currency":"USD"},{"qty":3300,"price":"$0.34500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7e0bb80ac6f9ae234873f64c6baf4f4d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/11LC020T-I%2FMNY/alternatives.json"},"ai":{"faq":[{"question":"Does 11LC020T-I/MNY require an external pull-up resistor?","answer":"Yes, the Single Wire interface is an open-drain bus that needs an external pull-up resistor to Vcc.
