Endurance is effectively unlimited for typical data-logging rates, and writes consume less energy per byte than an equivalent Flash write, which matters for battery-powered nodes that wake, sample, and go back to sleep.
The 2K x 8 RAM is modest — it's sized for register and stack storage while the FRAM handles persistent data.
ROHS3 compliance is confirmed.
The core runs at 16 MHz. At that clock rate the CPUXV2 core executes most instructions in a single cycle, giving roughly 16 MIPS throughput for control and sensor-processing tasks.
Yes. The supply range of 1.8V to 3.6V includes 3.3V, so the MCU interfaces directly with 3.3V peripherals without level shifting. The I/O pins are 3.3V-tolerant within that supply window.
