FRAM writes at bus speed with no erase penalty and endures 10^15 cycles — you can treat it like non-volatile SRAM for data logging or over-the-air firmware updates without wearing out the memory. The 16-TSSOP package (4.40 mm width) and 11 I/O suit compact sensor nodes, control panels, and battery-powered edge devices where board area is tight.
Capacitive touch and 5-channel 10-bit ADC — peripheral set for human-interface designs
The integrated Cap Sense peripheral handles capacitive-touch buttons, sliders, and proximity sensing without external charge-converter ICs — a BOM saving of a few dollars in volume. The 5-channel 10-bit ADC reads analog sensors or battery voltage directly. The internal oscillator frees up a pin and a crystal slot, though you'll still want a clean supply for the ADC reference.
The brown-out detect and POR ensure clean reset on power-up or battery sag; the watchdog timer guards against firmware hangs.
