Product details

Memory and data converter sizing for the BOM

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.

Package and footprint — 48-UFQFPN with exposed pad

Housed in a 48-UFQFN exposed-pad package (7x7 mm body), this MCU suits space-constrained designs where board area is at a premium. The exposed thermal pad needs a via stitch to the ground plane for heat dissipation — without it, continuous operation above 85°C ambient may push the junction beyond the rated limit. The 0.5 mm pitch requires careful solder paste volume control during assembly.

Frequently asked questions

What is STM32L4P5CGU6P's listed speed on this component line?

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.
