If your application needs more RAM or a larger display buffer, check the STM32L476RGT6 sibling with 1 MB Flash and 128 KB SRAM in the same 64-LQFP footprint. ## Connectivity and peripherals for field I/O Built-in CANbus, USB OTG, multiple UART/USART, I²C, SPI, and QSPI cover the common fieldbus and sensor interfaces. The LCD controller can drive a segment display directly — handy for a local readout on a pump controller or HVAC actuator. Brown-out detect and a watchdog timer are on-chip, so a simple external supervisor may be enough. ## Package and supply — fits a standard 64-pin LQFP layout Surface-mount only; no socket option, but the fine pitch is manageable with a standard soldering iron if you are careful.","metaTitle":"STM32L476RET6 STM32L4 ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STM32L476RET6 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 80MHz core, 512KB Flash, 128KB SRAM, 64-LQFP, industrial temp -40°C to 85°C.
