FRAM memory — no wear-leveling, no worry
That makes it a different animal from a Flash MCU: you can treat the FRAM like a combination of code space and EEPROM without managing wear-leveling or sector erase. The 2 KB of SRAM (2K x 8) handles runtime data. Clocked at 16 MHz, it keeps up with sensor polling, communication, and control loops in battery-powered or energy-harvesting designs.
CapSense and connectivity in a 20-pin package
With 15 I/O lines and integrated capacitive touch sensing (CapSense), this MCU can replace a separate touch controller in human-interface applications — think capacitive buttons, sliders, or proximity wake-up. The peripheral set includes a brown-out detect and reset, power-on reset, PWM, and watchdog timer, plus I²C, SPI, and UART serial interfaces. The 8-channel 10-bit ADC handles analog inputs like temperature or battery voltage. All of this fits in a 20-VQFN package with an exposed thermal pad (3.5x4.5 mm), which helps pull heat out in enclosed or warm environments.
The supply range of 2.0 V to 3.6 V covers single-cell Li-ion, two-cell alkaline, or 3.3 V regulated rails. The internal oscillator keeps the clock running without an external crystal, saving two pins and a component.
Lifecycle — still in active production
For BOM planning that means no last-time-buy pressure and no forced redesign in the near term.
