32 KB of on-chip Flash (32K x 8) with 8 KB of SRAM (8K x 8) is the memory envelope. The Flash holds the application code and constant tables; the SRAM covers stack, heap, and runtime data buffers. The 8 KB RAM also limits DMA buffer depth for high-rate ADC captures.
The internal oscillator and brown-out detect keep operation predictable.
The 28 GPIOs include I²C, SPI, and two UART interfaces.
The core runs at 50 MHz, which is the maximum clock for the ARM Cortex-M0 on this device.
It is rated for -40°C to 85°C ambient, suitable for industrial and outdoor applications.
