The 169-UFBGA package (7x7 mm) packs 140 I/O into a footprint that demands a four-layer PCB minimum and careful via fan-out under the BGA. This is not a prototype-friendly hand-solder package; expect to route it on a production board with microvias or at least a 0.2 mm via-in-pad strategy. ## Peripheral set and connectivity — what the 140 I/O actually buys The peripheral list includes CANbus, USB OTG, multiple SPI and I²C interfaces, SAI for audio, and an EBI/EMI bus that can gluelessly connect external SRAM or a parallel LCD controller. Brown-out detect, POR, and a programmable watchdog are on-chip, which simplifies the power-supervision BOM for industrial controllers that need to survive a glitch without corrupting Flash. The LCD peripheral drives a segment display directly — a feature that saves a dedicated driver IC in metering or point-of-sale designs. ## Lifecycle and sourcing posture STMicroelectronics lists the STM32L4P5AGI6P with an Active product status.","metaTitle":"ST STM32L4P5AGI6P ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4P5AGI6P 32-bit ARM Cortex-M4 MCU at 120 MHz with 1 MB Flash and 320 KB RAM in 169-UFBGA.

Moving to the STM32L4R9 series adds a larger SRAM option and a higher-resolution graphics LCD controller, but the pinout differs in the BGA ball map — verify against the STM32L4 reference manual before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4P5AGI6P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4P5AGI6P when reusing this data.
