The STM32L496VGT6TR is an STMicroelectronics 32-bit MCU built around an ARM Cortex-M4 core clocked at 80 MHz, with 1 MB of Flash program memory and 320 KB of SRAM. That memory map is the first thing to check: 1 MB Flash holds a full application stack including a real-time OS and communications protocol layers, while 320 KB RAM gives you room for data buffers and stack without reaching for external SRAM. The 100-LQFP package brings out 83 I/O lines, enough for a control panel with a parallel LCD, keypad matrix, and a handful of sensors. Connectivity covers CANbus, USB OTG, QSPI, and SAI, which means this part can talk to a CANopen fieldbus, log data to a USB stick, and drive an audio codec without glue logic.
It is not qualified to AEC-Q100, so it is not the pick for an under-hood ECU or a chassis-domain controller.
