Sequential reads and writes within a page are supported; crossing a page boundary requires a new start condition. For a firmware-update routine writing 256 bytes, each page write takes 5 ms, so a full 8 Kbit (1 KByte) update completes in about 20 ms plus bus overhead. Access time is 900 ns — this is the time from the address latch to data valid on the bus; the I²C clock period (2.5 µs at 400 kHz) dominates the read latency. ## Package and lifecycle — active, no end-of-life pressure The footprint matches industry-standard 24AAxx and 24LCxx devices — a direct drop-in for existing layouts using those parts. Lifecycle status is active per Microchip, with ROHS3 compliance — no last-time-buy clock, no exemption paperwork for EU or California markets.","metaTitle":"Microchip 24AA08-I/SN EEPROM, 8 Kbit, I²C, 8-SOIC","metaDescription":"Microchip 24AA08-I/SN 8 Kbit I²C EEPROM, 400 kHz, 1.7-5.5 V, -40 to +85 °C, 8-SOIC.
