16Kbit FRAM with I²C — instant non-volatile writes
The FM24CL16B-DG: 16Kbit FRAM organized as 2K x 8 bits, accessed via I²C at 1 MHz. 550 ns access time for both reads and writes.
1 MHz I²C clock and 550 ns access time. 16Kbit density (2K x 8).
EOL lifecycle stage. Base product number FM24CL16 remains active.
Where it is used
FRAM in this density and interface is common in smart meters, industrial sensors, medical monitors, and IoT edge nodes that need to retain calibration data or event logs through power loss without battery-backed SRAM. The I²C bus keeps the pin count low — two wires plus power — so it fits into space-constrained designs alongside a microcontroller.
