FRAM MCU for industrial sensing and control
Its program memory is 64 KB of FRAM — a non-volatile, fast-write, high-endurance memory that eliminates the erase-before-write penalty of Flash and needs no wear-leveling in the firmware layer. The 2 KB SRAM (2K x 8) handles stack and scratchpad data. With 51 general-purpose I/O lines, an internal oscillator, and a 12-bit ADC with eight multiplexed channels, this part targets sensor fusion nodes, metering, and industrial control loops where low power and deterministic write performance matter.
Supply range and power rail design
Dropout margin at the low end is tight — if the supply dips below 1.8 V the brown-out detect (BOD) resets the core cleanly. The POR and BOD peripherals are integrated, so no external supervisor is needed for most designs.
It suits outdoor telecom cabinets, factory-floor sensor nodes, motor-drive control boards, and under-hood automotive auxiliary modules (non-safety-rated).
Peripherals and connectivity
On-chip peripherals include a DMA controller for memory-to-peripheral transfers without CPU loading, PWM timers for motor or LED drive, and a watchdog timer. The 12-bit ADC with eight channels samples at rates adequate for slow-loop feedback (temperature, pressure, current sense).
