64.5 KB FRAM — the real differentiator
Its standout feature is 64.5 KB of FRAM program memory — non-volatile, byte-addressable, and rated for 10¹⁵ write cycles — which eliminates the erase-before-write penalty of Flash and supports frequent data logging or firmware field updates without wear-leveling overhead. The 8 KB of SRAM handles stack and scratchpad for real-time control loops.
Industrial temperature range and peripheral set
The 10-channel 12-bit SAR ADC captures sensor inputs directly, while the UART, SPI, I²C, and IrDA interfaces handle common serial protocols. 35 GPIOs give enough headroom for a keypad, display, and a few external peripherals without a port expander.
