168 MHz Cortex-M4 with 1 MB Flash — real-time control headroom
The STM32F417IGT7: That clock rate and memory budget handle a motor-control FOC loop or a multi-axis servo profile without spilling into external memory — the 192 KB SRAM holds the rotor position tables and the commutation state machine simultaneously. The 140 general-purpose I/O lines in the 176-LQFP package give the layout engineer room to route a parallel LCD bus, an external memory interface (EBI/EMI), and a camera interface (DCMI) alongside the primary control signals, all within a single 24x24 mm footprint.
Industrial temperature grade and connectivity for field-deployed controllers
On-chip Ethernet MAC with dedicated DMA, two CAN 2.0B interfaces, and a USB OTG HS port let this MCU act as the fieldbus gateway in a distributed control system — it talks to the PLC over EtherCAT or CANopen while logging telemetry to a USB flash drive, all without an external network coprocessor. The 24-channel 12-bit ADC with 2.4 MSPS aggregate sample rate captures three-phase current feedback and a resolver position signal in a single conversion sequence, while the dual 12-bit DAC outputs the analog setpoint for a downstream analog drive.
The base product number STM32F417 covers the full family, and this variant is the extended-temperature (-40 to 105°C) version in the 176-LQFP tray. No minimum order threshold beyond the tray quantity.
