Product details

The STM32L4P5CGU6: 120 MHz Cortex-M4 core with FPU handles real-time math. 1 MB Flash supports OTA staging; 320 KB SRAM fits a VGA frame buffer.

Connectivity and peripheral mix — what is on the bus

CAN interface connects to industrial actuator networks. USB OTG supports field firmware updates. EBI/EMI maps external SRAM or display controller into memory space.

Package and board integration — 48-UFQFPN with exposed pad

The part comes in a 48-lead UFQFPN with an exposed pad (7x7 mm footprint).

Active status allows qualification for new production builds. STM32L151CBU6A is a functional alternate at a lower performance tier: Cortex-M3 at 32 MHz. No pin-compatible second source in STM32L4 family at this density and package.

Frequently asked questions

What is the equivalent of STM32L4P5CGU6?

The STM32L151CBU6A is a functional alternate from the STM32L1 series, but it runs a Cortex-M3 at 32 MHz with 256 KB Flash — a different performance tier. For a closer match within the same L4 family, look at the STM32L4R5CGU6, which shares the 48-pin UFQFPN footprint and Cortex-M4 core, though its memory and peripheral set differ. No pin-compatible second source exists at this exact density and package.
