For a production BOM that already qualifies this 100-WLCSP variant, the supply outlook is stable. ## 80 MHz Cortex-M4 with 1 MB Flash — what the memory and speed mean for fit That Flash density supports a full RTOS, a TCP/IP stack, and a moderate application image with room for field-upgrade staging. The 320 KB SRAM covers double-buffered graphics frames or a large audio buffer without external memory. The Cortex-M4 includes a single-precision FPU and DSP instructions, so sensor fusion or motor-control loops run in firmware rather than needing a separate coprocessor. ## Peripheral set and connectivity — what is on-chip An integrated LCD controller drives segment displays directly. Brown-out detect and a watchdog timer are built in, reducing external supervisory IC count. ## 100-WLCSP package — board-level considerations This part comes in a 100-ball WLCSP (4.62 x 4.14 mm body). The fine-pitch wafer-level package saves board area but requires a controlled SMT process — the solder mask and stencil aperture need to match the 0.4 mm ball pitch. The 83 I/O count in this footprint gives good routing density for a mixed-signal design. ## Supply voltage and power profile The STM32L4 series is ST's ultra-low-power line; the active current at 80 MHz is typically under 100 µA/MHz in run mode, and stop-mode draw drops to a few microamps. For battery-powered or energy-harvested designs, this part is sized to extend run time.","metaTitle":"STM32L4A6VGY6TR STMicroelectronics ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STM32L4A6VGY6TR is an STMicroelectronics 32-bit ARM Cortex-M4 MCU with 80 MHz core, 1 MB Flash, 320 KB SRAM, rich connectivity, in 100-WLCSP.","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":"Tape & Reel (TR)","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":"83","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 16x12b; 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":"100-WLCSP (4.62x4.14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8551","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/45a657a8843525c9cb73383b660a07f2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L4A6VGY6TR RoHS compliant?","answer":"The STM32L4A6VGY6TR is listed as RoHS compliant per STMicroelectronics standard product marking.
