The 1 MB Flash allows a single-chip firmware image with a bootloader, application code, and a redundant OTA staging slot — no external serial Flash needed for many designs. The 128 KB SRAM supports a full FreeRTOS or Zephyr instance with several 1 KB sensor buffers and a USB packet FIFO. If your application requires more than 128 KB of RAM, you will need to budget for an external SRAM or SDRAM via the QSPI or FMC interface. ## Connectivity and analog peripherals — what is on-chip The STM32L486RGT7 integrates a CAN 2.0B controller for industrial fieldbus, a USB OTG FS for device/host/OTG roles, and a Quad-SPI interface for memory-mapped external Flash or PSRAM. The SAI (serial audio interface) connects to I²S codecs for voice or audio playback. The LCD controller drives segment-type glass displays directly, saving a separate display driver IC. ## Package and footprint — 64-LQFP 10x10 mm Housed in a 64-lead LQFP with a 10x10 mm body and 0.5 mm pitch, this package is straightforward to route on two-layer boards and is reworkable with standard hot-air tools. The 51 I/Os give enough headroom for a parallel LCD data bus, external memory address lines, and several sensor interfaces simultaneously. The part is ROHS3 compliant.","metaTitle":"STM32L486RGT7 STM32L4 MCU, 80 MHz, 1 MB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32L486RGT7 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 128 KB SRAM, -40°C to 105°C, 64-LQFP.
