The STM32L4P5CGU6P: The 1 MB Flash and 320 KB SRAM support OTA updates and double-buffered graphics. The 12-bit ADC with 16 channels and dual 12-bit DACs cover sensor conditioning and closed-loop control.
The 0.5 mm pitch requires careful solder paste volume control during assembly.
The STM32L4P5CGU6P is rated for a 120 MHz core speed on the ARM Cortex-M4 processor. This determines the maximum instruction throughput and sets the timing budget for real-time control loops and peripheral data rates.
