Frequently asked questions
What replaces the M24C01-WDW6TP?
No official ST-issued successor order code appears in this record. The density-up variants M24C02 (2 Kbit) and M24C04 (4 Kbit) share the same TSSOP-8 footprint and I²C protocol, making them the natural step-up for new designs — but confirm pinout and address allocation before substituting on an existing board.
What does the 5 ms write-cycle time mean at elevated temperature?
The 5 ms figure is the nominal write-cycle time under rated conditions. At 70°C panel ambient the datasheet's thermal derating curve governs whether this budget stretches — for a 10 ms byte-write budget, confirm the temperature-adjusted spec before locking the BOM.
