It packs 1 MB of Flash and 320 KB of RAM, which puts it in the high-density tier of the STM32L4 series — enough headroom for a real-time control loop, a communication stack, and a local data buffer without external memory. The 80 MHz core with a single-cycle multiply and a hardware FPU (single-precision) handles sensor fusion, motor-control math, or audio filtering without a separate DSP. The 320 KB of SRAM is large enough to hold a double frame buffer for a small graphical display or a ping-pong DMA buffer for high-speed ADC captures. The 1 MB Flash is split into 2 KB and 4 KB pages, which matters for wear-leveling in data-logging applications — you can erase small sectors without disturbing the rest of the code space. For a production BOM, this removes the obsolescence risk that can force a costly redesign. If you are qualifying this MCU for a new design, the active status gives you a multi-year procurement window before any end-of-life planning is needed. ## Package and footprint — what to plan for on the PCB The 169-UFBGA package measures 7×7 mm with a 0.5 mm ball pitch. That is a fine-pitch BGA that requires a controlled solder-paste stencil and a reflow profile for lead-free assemblies. The small footprint saves board area compared to an LQFP-144, but the hidden balls mean X-ray inspection is the only way to verify solder-joint quality after reflow. ## Sourcing this part — what to expect Because the STM32L4A6AGI6P is an active, high-volume STM32 variant, it is widely stocked across the independent distribution channel. There is no need to chase a last-time-buy window or accept a broker premium for a discontinued line. The active status also means factory lead times are generally predictable, though they can stretch during allocation cycles.","metaTitle":"ST STM32L4A6AGI6P MCU, ARM Cortex-M4, 80MHz, 1MB Flash","metaDescription":"STMicroelectronics STM32L4A6AGI6P 32-bit MCU with ARM Cortex-M4 core at 80MHz, 1MB Flash, 320KB RAM, 136 I/O, 169-UFBGA.","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":"136","Core Processor":"ARM® Cortex®-M4","Package / Case":"169-UFBGA","Product Status":"Active","Data Converters":"A/D 24x12b; 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":"169-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.6300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/45a657a8843525c9cb73383b660a07f2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the differences between STM32L4A6AGI6P and STM32L4A6RG?","answer":"The STM32L4A6RG is a different package variant (typically 64-pin LQFP) with fewer I/O and less memory than the STM32L4A6AGI6P. The STM32L4A6AGI6P offers 136 I/O, 1 MB Flash, and 320 KB RAM in a 169-UFBGA package, while the STM32L4A6RG has 51 I/O, 1 MB Flash, and 320 KB RAM in a 64-pin LQFP.
