What the 80 MHz and memory mean for your BOM
The 128 KB SRAM supports moderate-sized data buffers and a real-time OS with a few tasks. 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.
