The STM32L486RGT6TR is an STMicroelectronics ARM Cortex-M4 MCU from the STM32L4 series, built around a 32-bit single-core processor running at 80 MHz. It carries 1 MB of Flash and 128K x 8 of SRAM, which gives firmware engineers room for a full RTOS, DSP library, and OTA staging without squeezing into a smaller density tier.
The peripheral list includes CANbus, USB OTG, QSPI, SAI, and a 16-channel 12-bit ADC plus a 2-channel 12-bit DAC — enough interface diversity to handle sensor fusion, motor feedback, and human-machine interface on one chip. 51 GPIOs in the 64-LQFP package leave room for parallel displays or memory-mapped peripherals.
