120 MHz Cortex-M4 with 1 MB Flash — memory headroom for complex firmware
The STM32L4P5VGT6P: ARM Cortex-M4 MCU at 120 MHz with 1 MB Flash, 320 KB RAM, 83 I/O, in 100-LQFP. Peripherals include CANbus, USB OTG, and I²C.
1 MB / 320 KB — sizing the firmware and data footprint
1 MB Flash and 320 KB RAM. The Flash is 1M x 8.
Connectivity and analogue — what the peripheral list tells you
The LCD peripheral suggests this part was designed with segment-display HMI panels in mind — common in industrial meters, appliance control boards, and medical front panels.
100-LQFP (14x14 mm) package.
For a production BOM, this part carries no last-time-buy risk today. If you are dual-sourcing for resilience, the base product number STM32L4P5 covers multiple density and package variants on the same die — the 100-pin LQFP footprint is shared across the STM32L4P5 family, so a swap to a sibling with different memory is a firmware recompile, not a board spin.
