What the LPC5536JBD100K brings to a control board
The NXP LPC5536JBD100K is a 32-bit ARM Cortex-M33 microcontroller running at 150 MHz, with 256 KB of Flash and 128 KB of SRAM. It carries a 23-channel 16-bit ADC and a 2-channel 12-bit DAC on-chip, plus a full set of serial interfaces including CAN, Flexcomm (configurable as I2C, SPI, UART), I3C, and USB 2.0. The 66 GPIOs in a 100-LQFP package give enough headroom for a sensor-fusion board or a small industrial controller without needing an external expander.
150 MHz Cortex-M33 — what it means for the loop
The 150 MHz clock on a Cortex-M33 with single-cycle multiply and hardware divide means this part can handle a real-time control loop (motor FOC or a PID cascade) and still have MIPS left for a protocol stack. Combined with the DMA engine and the programmable Flexcomm interface, you can keep the core on control while the peripherals shuffle data from the ADC to memory or from memory to the DAC.
Industrial temperature grade and package
Rated from -40 to 105 °C. The 100-LQFP (14x14 mm) is a standard fine-pitch QFP.
