64Kbit I²C EEPROM — NRND lifecycle reality
The M24C64-WMN6TP: Its lifecycle status is NRND (Not Recommended for New Designs) — the part is still available for existing production but STMicroelectronics advises against starting new board spins with this order code. For a new design, the buyer should evaluate the current-generation M24C64 series devices in the same SOIC-8 footprint; the NRND flag means the factory will eventually end-of-life this variant without a pin-compatible drop-in from the same manufacturer.
Supply voltage and temperature grade
The 450 ns access time and 5 ms write cycle (word or page) are typical for this density class — the page-write buffer lets the bus burst up to 64 bytes before the internal programming cycle locks the part.
SOIC-8 package and board integration
Supplied on Tape & Reel (cut tape option available), the reel quantity suits automated pick-and-place assembly for medium-to-high volume runs.
