8-UFDFPN (2x3) footprint and board-fit
The M24C32-XMC5TG ships in an 8-UFDFN exposed pad package (supplier package 8-UFDFPN, 2x3 mm). The 0.50 mm pitch peripheral pads fan out to inner-layer traces; a 2-layer board handles the routing if the decoupling capacitor sits within 3 mm of the supply pin. Tape & Reel (TR) and Cut Tape (CT) packaging options are listed — the reel quantity suits automated pick-and-place; the cut tape is for prototype or low-volume builds where a full reel is not justified.
Supply voltage range and I²C bus compatibility
The I²C interface is specified at 1 MHz clock frequency — fast-mode plus (FM+) compliant — so the bus timing meets the 1000 kHz ceiling for high-throughput parameter storage or boot-configuration reads. The 32Kbit (4K x 8) organization stores 4096 bytes. Write cycle time is 5 ms per word or page — a full 16-byte page write completes in 5 ms, not 5 ms per byte, so bulk writes to sequential addresses are faster than single-byte writes.
This is the industrial temperature floor for equipment that operates indoors or in sheltered outdoor enclosures — telecom base stations, factory-floor controllers, and instrumentation racks. The -20°C lower limit means the part is not specified for cold-start below freezing; a -40°C variant (M24C32-DRDW3TP/K, AEC-Q100) exists for automotive or outdoor deployment. ROHS3 compliant.
