The NXP LPC1765FBD100K is a 32-bit ARM Cortex-M3 microcontroller running at 100 MHz, with 256 KB of Flash and 64 KB of RAM.
100 MHz Cortex-M3 — what it buys you
At 100 MHz, this core handles a real-time control loop and still has cycles left for CANbus message handling and a UART stack. The 64 KB of RAM is enough for moderate data buffers.
The CANbus controller is the standout for industrial networking — it saves an external CAN transceiver interface chip. USB OTG adds device/host flexibility for field-upgrade or data-logging scenarios. The motor-control PWM and the I²S audio interface are less common on a mid-range MCU; if you need neither, you are still paying for the silicon, but the CAN and USB alone justify the part for many BOMs.
The 70 I/O are accessible on all four sides, so layout for a mixed-signal design with the ADC inputs kept away from the PWM outputs is straightforward.
