Frequently Asked Questions (FAQ)
Is the obsolete AT24C02N-10SC-1.8 still safe for a 0–70 °C industrial sensor node, or should I migrate to the M24C02-RMN6TP before the next 5-year re-design cycle?
Keep the AT24C02N-10SC-1.8 only if your board never sees >70 °C in-cabinet hotspots—its 0–70 °C rating has no head-room. For 5-year longevity, migrate to the M24C02-RMN6TP; it gives –40–85 °C, 1 MHz I²C and is footprint-compatible in 8-SOIC, eliminating thermal margin risk and future obsolescence buy-again.
Can I drop the AT24C02N-10SC-1.8 on the same 3.3 V I²C bus as a 1.2 V MCU without level-shifting, and what’s the glitch risk during a 1 ms power-brown-out?
The AT24C02N-10SC-1.8’s 1.8 V minimum VIL allows direct 1.2 V drive, but its VIH max sits at 0.7 VCC—on a 3.3 V rail you’ll violate logic-high thresholds if the MCU only outputs 1.2 V. Add a $0.04 N-channel FET level-shifter; this also prevents corruption during brown-out because the EEPROM’s internal write-state-machine can grab a partial 3.3 V supply and create byte-error. Insert 100 nF close to VCC and a 10 kΩ pull-down on SDA to mask transients <1 ms.
I need 5 ms page-write timing on the AT24C02N-10SC-1.8 but my firmware polls ACK every 1 ms; will this prematurely wear the 256-byte array, and how does it compare vs. the FT24C02A-USR-B?
Polling ACK every 1 ms is fine—AT24C02N-10SC-1.8 self-times for 5 ms and simply NACKs until complete, so no extra cycles are burned. Write-endurance remains 1 M cycles per byte, identical to FT24C02A-USR-B. Difference: FT24C02A offers a 32-byte page vs. 8-byte here, reducing total write traffic by 4× if you stream logs; switch only if your Super-Loop can’t sleep during long 5 ms blocks.
Clock-stretching by a slow slave stalls my 400 kHz STM32 I²C; will the AT24C02N-10SC-1.10SC-1.8 stretch longer than 2 ms and starve a 1 kHz control loop?
AT24C02N-10SC-1.8 never stretches beyond 900 ns read/5 ms write—far below your 1 kHz budget. If you still see >300 µs low-SCL, check competing slaves. Isolate the EEPROM on its own I²C segment with a PCA9306 buffer so high-speed peripherals stay unaffected; the 8-SOIC keeps PCB channels identical.
Microchip marks AT24C02N-10SC-1.8 as non-RoHS; will the tin-lead plating cause EU RoHS 10/12 exemptions to expire in 2024, and can I sub 24LC02BT/SN today without re-spinning the 8-SOIC pad pattern?
Yes—exemption 7(a) expires July 2024, so the SnPb AT24C02N-10SC-1.8 becomes import-restricted. Drop-in the RoHS-compliant 24LC02BT/SN; both share 8-SOIC 3.90 mm footprint, 400 kHz I²C and 2 kbit density. Re-validate write-time: 24LC02BT specs 5 ms max page identical to legacy, so your timing budget remains intact and no firmware tweak is required.
