80 MHz Cortex-M4 with 1 MB Flash — BOM-fit for signal-chain processing
The STM32L471RGT6 runs an ARM Cortex-M4 core at 80 MHz, delivering the throughput to handle sensor fusion or real-time control loops without an external DSP. 1 MB of on-chip Flash and 128 KB SRAM leave headroom for a full application stack — HAL, RTOS, and a moderate-size communications buffer — without needing external memory. 51 I/O lines in a 64-LQFP package give enough pins for a parallel display interface or a bank of sensors while still fitting a compact 10x10 mm footprint.
Industrial temp range and wide supply — deployment in factory-floor and battery gear
Rated -40 to 85°C ambient, the part suits outdoor IoT gateways, motor-drive control boards, and other enclosures that see seasonal temperature swings. Built-in brown-out detect and POR eliminate the need for an external supervisor in most designs — the MCU resets cleanly as the rail rises.
Connectivity and data converters — one-chip node for CAN and mixed-signal
CANbus, multiple SPI/I²C/UART, and QSPI let the MCU talk to a CANopen fieldbus, a serial Flash, and a sensor array without glue logic. 16-channel 12-bit ADC and dual 12-bit DAC cover analog front-end needs — temperature, current sense, and setpoint outputs all on one die.
ROHS3 compliant, so it passes EU and global environmental requirements without a waiver.
