116 KB Flash, 8 KB RAM — firmware and data budget
116 KB of Flash is generous for a 16-bit MCU running a real-time operating system or a complex measurement algorithm with a calibration table. The 8 KB RAM is the tighter constraint: it holds the stack, the ADC buffer, and any DMA ring buffers. If your application needs to store a full-screen bitmap for the LCD driver or buffer several seconds of multi-channel ADC data, budget the RAM allocation early. The Flash is field-reprogrammable, so firmware updates over UART or I²C are possible without a programmer.
Integrated 12-bit ADC and DAC — mixed-signal on one die
The 12-channel 12-bit ADC and dual 12-bit DAC eliminate external converters in many sensor-conditioning and control loops. The ADC handles up to 12 single-ended inputs; the two DACs can generate analog setpoints or bias voltages.
