Core and memory sizing for the BOM
The STM32G071CBT6TR runs a 32-bit ARM Cortex-M0+ core at 64 MHz — this is the throughput ceiling for the application, and the flash wait-state profile at this clock determines actual execution speed, not the core alone. 128 KB of on-chip flash (128K x 8) and 36 KB SRAM (36K x 8) provide the program and data memory budget; the flash is sufficient for a mid-complexity firmware stack with a real-time OS, while the SRAM supports moderate data buffers and stack depth.
Peripheral set and analog integration
The 17-channel 12-bit ADC and dual 12-bit DAC eliminate the need for external analog front-ends in many sensor and actuator loops — the ADC covers multiple analog inputs, and the DAC outputs drive set-point voltages directly. The HDMI-CEC interface is a niche addition for consumer AV applications.
