The 120 MHz ARM Cortex-M4 core includes a single-precision floating-point unit, so control loops with PID or sensor fusion math run without software emulation overhead. For firmware bring-up, the internal oscillator gets you running immediately, but hitting the full 120 MHz requires setting one flash wait state before raising the core clock — skip that step and the first branch instruction hard-faults. The 320 KB SRAM gives enough headroom for double-buffered graphics on a small LCD, audio buffers, or multiple protocol stacks without external memory. With 1 MB of Flash, you can stage over-the-air firmware updates and still leave room for a full RTOS image. ## Connectivity and peripherals for a single-chip system This MCU integrates USB OTG for host or device mode, CANbus for industrial networks, multiple I²C and SPI buses for sensor arrays, and a full set of UART/USART ports with IrDA and LIN support. The EBI/EMI interface can drive external parallel memory or displays, and the SAI peripheral handles I²S audio. On the analog side, there are sixteen 12-bit ADC channels and two 12-bit DACs, enough for multi-channel data acquisition without external converters. The LCD controller drives glass displays directly, saving a separate driver IC on metering and control panels. No exposed thermal pad here — dissipation goes through the leads, so keep the ambient airflow in mind if the core runs sustained DSP loads. The 0.5 mm pitch means a standard 0.3 mm tip on the rework station works for hand-soldering prototypes, but use a hot-air station for removal to avoid lifting pads. The base product number STM32L4P5 covers the full density and package options in the series, so if the 48-LQFP footprint is tight, the 64-pin or 100-pin variants share the same peripheral set and code base.","metaTitle":"STM32L4P5CGT6 MCU, ARM Cortex-M4, 120MHz, 1MB Flash, 48-LQFP","metaDescription":"STM32L4P5CGT6 32-bit MCU with 120MHz Cortex-M4, 1MB Flash, 320KB SRAM, USB OTG, CAN, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"120MHz","Series":"STM32L4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L4P5","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.1500","priceTiers":[{"qty":1,"price":"$14.15000","currency":"USD"},{"qty":10,"price":"$13.00100","currency":"USD"},{"qty":25,"price":"$12.46240","currency":"USD"},{"qty":80,"price":"$10.98050","currency":"USD"},{"qty":250,"price":"$10.44160","currency":"USD"},{"qty":500,"price":"$9.76794","currency":"USD"},{"qty":1000,"price":"$9.18615","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/864b0095aefddec5383cd033b8022454.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L4P5CGT6/alternatives.json"},"ai":{"faq":[{"question":"What is STM32L4P5CGT6's listed speed?","answer":"The core processor runs at 120 MHz, based on the ARM Cortex-M4 with single-precision FPU.
