FRAM-based 16-bit MCU with 128 KB unified memory
Its standout feature is 128 KB of FRAM (ferroelectric RAM) program memory — a non-volatile storage that writes at near-SRAM speed, consumes negligible power, and supports 10^15 write cycles, making it a practical choice for data-logging, metering, and sensor-node applications where frequent field updates or persistent state storage is needed. The device also includes 2K x 8 of SRAM for stack and scratchpad use.
Peripheral set and connectivity
On-chip peripherals include a brown-out detect, DMA controller, POR, PWM timer, and watchdog timer. Twelve 12-bit ADC channels handle analog inputs without an external converter.
64-VQFN package — rework and layout notes
The pad also serves as a ground return. During rework, preheat the board to 125°C and use a hot-air profile that ramps slowly to avoid lifting the pad — the exposed paddle wicks heat fast.
No last-time-buy or substitution risk for current designs.
