That means the same part can handle a PID loop, a sensor-fusion filter, and a FFT without a separate DSP. The 1 MB Flash is organized as 1M x 8 with read-while-write capability, so you can update application code in one bank while executing from the other — useful for field firmware upgrades over CAN or USB. ## Memory headroom and connectivity for system integration With 320 KB of SRAM, this MCU can buffer several audio frames or a full display frame without external memory. The QSPI interface lets you add up to 256 MB of external Flash or PSRAM for data logging or font storage. The CAN 2.0B controller handles 2.0A/B frames and is a standard node on industrial and automotive networks. USB OTG (full-speed) supports host or device mode, so you can connect a USB stick for data logging or a keyboard for HMI input — no external PHY needed for full-speed. ## Package and temperature grade: 132-UFBGA at 7x7 mm The 132-ball UFBGA package measures 7x7 mm with a 0.5 mm ball pitch. No successor has been announced; the STM32L4 series is a mature, well-supported family with long-term supply commitment from STMicroelectronics.","metaTitle":"STM32L4A6QGI6P ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4A6QGI6P 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 1 MB Flash, 320 KB SRAM, 110 I/O, CAN, USB OTG, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"110","Core Processor":"ARM® Cortex®-M4","Package / Case":"132-UFBGA","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L4A6","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"132-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9931","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/45a657a8843525c9cb73383b660a07f2.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4A6QGI6P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4A6QGI6P when reusing this data.
