The NXP LPC5504JHI48QL is a 32-bit ARM Cortex-M33 microcontroller from the LPC550x series, clocked at 96 MHz. The Cortex-M33 includes a single-cycle multiply-accumulate and a Memory Protection Unit, which helps isolate safety-critical tasks from the application layer in industrial drives or motor controllers.
Connectivity mix: CAN bus plus Flexcomm flexibility
The MCU includes a CAN bus controller and a Flexcomm peripheral configurable as I2C, SPI, or UART. The 7x16b SAR ADC provides seven analog inputs.
Peripherals include brown-out detect, power-on reset, DMA, I2S, PWM, a random-number generator, and a watchdog timer — the usual complement for a safety-aware industrial MCU.
