Cortex-M3 at 48 MHz — the control-loop ceiling
It packs 16 KB of Flash and 4 KB of SRAM — enough for a lightweight RTOS and sensor-fusion or protocol-stack firmware in industrial and IoT edge nodes.
16 KB Flash, 4 KB SRAM — sizing the firmware footprint
With 16 KB of program memory (16K x 8) and 4 KB of SRAM (4K x 8), this part fits single-loop control, Modbus or I²C sensor polling, and simple HMI logic. The 4 KB RAM limits buffered data-logging or large lookup tables — plan for register-level or DMA-driven peripheral transfers to stay within budget.
Industrial temp range and peripheral set
The 10-channel 10-bit ADC and single 10-bit DAC cover basic analog sensing and set-point output.
64-QFN package — layout and thermal handling
The exposed paddle must be connected to ground (or the appropriate supply plane) per the datasheet layout guidelines. The 0.50 mm pitch QFN demands a solder-paste stencil with proper aperture design to avoid bridging on the centre pad.
No LTB or end-of-life risk for new designs.
