FRAM vs Flash — what it means for the BOM
32 KB FRAM program memory writes at bus speed without a page-erase cycle. Endurance is effectively unlimited for practical embedded lifetimes.
Industrial temperature grade and peripheral set
The -40°C to 85°C operating range covers most industrial environments, including outdoor cabinets and engine-adjacent enclosures without active cooling. On-chip peripherals include a brown-out detect and reset, DMA controller, POR, PWM, and watchdog timer — enough to handle sensor polling, motor control loops, and communication scheduling without external supervision. Connectivity covers I²C, SPI, UART, and IrDA, which matches common sensor and actuator bus protocols. The internal oscillator eliminates the need for an external crystal in many designs, though the device can accept an external clock if tighter timing is required.
