The M24C16-WDW6TP is a 16Kbit serial EEPROM from STMicroelectronics, organized as 2K x 8 bits, accessed through a standard I²C interface at 400 kHz. Supply voltage spans 2.5V to 5.5V. The 900 ns access time and 5 ms page write cycle are typical for this density class — the 900 ns is the read cycle time, not the initial access; the bus clock sets the throughput.
Package and temperature grade — board-fit check
Housed in an 8-TSSOP (0.173", 4.40mm width) package, the part is surface-mount and supplied on Tape & Reel (Cut Tape also available).
NRND — sourcing and lifecycle posture
For existing BOM lines, the part remains available through the supply chain — we source and quote to order against your quantity; confirm current lead time and pricing at quote time. Designers starting a new project should evaluate a pin-compatible alternative from the M24C16 family.
