The host firmware must either poll the acknowledge polling sequence or insert a 5 ms delay before the next write. If the system writes configuration data on every power-up, that 5 ms window adds to the boot time budget. For a LoRa end-node waking from deep sleep, a 5 ms write lockout is acceptable — the wake-up energy spent transmitting a packet dwarfs the EEPROM write energy. ## Lifecycle and sourcing posture New designs can commit this part without an obsolescence watch. ## Through-hole package — board fit and handling The 8-DIP (0.300\" row spacing) package fits standard 0.1\" pitch prototyping boards and sockets. It is not a moisture-sensitive device — no bake required before hand-soldering or wave-solder. The PDIP body stands up to repeated soldering cycles, so it is a good choice for rework-lab test jigs or field-upgrade boards where the EEPROM may be socketed. Keep the leads clean; the tin-plated copper leads solder readily with a 350°C iron in 2–3 seconds per pin.","metaTitle":"Microchip 24LC02B-E/P 2Kbit I²C EEPROM, 900 ns","metaDescription":"Microchip 24LC02B-E/P 2Kbit I²C EEPROM, 900 ns access time, 400 kHz clock, 2.5V-5.5V, -40°C to 125°C, 8-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Package":"Tube","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2.5V ~ 5.5V","Memory Organization":"256 x 8","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-PDIP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.48","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.48000","currency":"USD"},{"qty":25,"price":"$0.46640","currency":"USD"},{"qty":100,"price":"$0.43460","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/09fd1810eb9252a439d4d616af217ead.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the 24LC02B-E/P be used as a drop-in replacement for the 24LC02B?","answer":"The 24LC02B-E/P is the extended-temperature version of the standard 24LC02B.
