The 128 KB SRAM supports moderate-sized frame buffers or data logging without external memory. 82 I/Os give enough headroom for a parallel LCD (EBI/EMI), external memory-mapped QSPI Flash, and a CAN bus node on the same chip. The peripheral set includes USB OTG (host or device), multiple SPI/I²C, SAI for audio, and SWPMI for smartcard interfaces. The 16-channel 12-bit ADC and dual 12-bit DAC cover analog front-end tasks like current sensing or signal conditioning without an external converter.","metaTitle":"ST STM32L476VGT3 ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L476VGT3 32-bit ARM Cortex-M4 MCU, 80 MHz core, 1 MB Flash, 128 KB RAM, -40 to 125 °C, 100-LQFP.
