M24C02-WMN6TP

M24C02-WMN6TP is an STMicroelectronics M24C02 2-Kbit (256 × 8) serial I2C EEPROM in 8-pin SOIC, tape-and-reel packing (TP) — configuration, calibration and identity storage for industrial and consumer boards. ST's current figures for this code: 400 kHz Fast-mode I2C, a 16-byte page write with 5 ms self-timed programming, and endurance and retention that are temperature-graded in the datasheet's tables (DS3938 Rev. 8, Tables 10–11, stated as maxima and minima inside the recommended supply range): 4,000,000 write cycles at TA ≤ 25 °C and 1,200,000 at 85 °C, with data retention of 200 years minimum at TA = 55 °C — neither figure is an unconditional lifetime promise at every temperature. The W supply range is the selection point: this variant runs at 2.5 to 5.5 V, while the M24C02-RMN6TP also listed on this site covers 1.8 to 5.5 V — ST itself cross-references the R code as the replacement product, but the two are not interchangeable in a design that must write below 2.5 V, so the supply letter on the BOM is a functional specification, not a packing detail. ST's own Quality & Reliability table lists this exact code as Active (SO8, Industrial grade, Ecopack2), superseding older not-recommended mentions of the code. Selection advice: 2 Kbit is 256 bytes — size the density before ordering, since the M24C family spans 1 Kbit to 16 Kbit in the same footprint. Parameters verified against the ST product page.
