The BR24T04FJ-WE2: Cut Tape works for prototype or low-volume builds.
Page and word write cycles complete in 5 ms typical — this is the bus-lock time per write command; the I²C master must wait this interval before addressing the device again.
ROHS3 compliant — the part meets the latest EU restriction-of-hazardous-substances directive for lead, mercury, cadmium, and phthalates.
The device is organized as 512 x 8 bits, giving 4Kbit of non-volatile storage. The I²C interface addresses it at a single 7-bit slave address with a word-address pointer for byte or page access.
