FRAM program memory writes without an erase cycle and has effectively unlimited endurance. 16 KB is the maximum density in this package.
The device operates from 2 V to 3.6 V, covering single-cell Li-ion and two-cell alkaline battery profiles without a regulator. The -40°C to 85°C industrial temperature range qualifies it for outdoor telecom cabinets, factory-floor sensor nodes, and engine-bay-adjacent electronics where the ambient stays below 85°C.
The core runs at 24 MHz, which is the maximum clock rate for this device.
