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.
