NXP – Power-efficient ARM Cortex-M4-based MCU ideal for HMI applications


Offering great flexibility and a scalable choice of performance options, the LPC546xx microcontroller family from NXP Semiconductors runs at speeds of up to 180MHz while drawing as little as 120μA/MHz. The MCUs’ 21 communication interfaces make them ideal for human-machine interfaces and for the connectivity needs of new IoT applications.

The LPC546xx MCU family, powered by the ARM® Cortex,sup>®-M4 core, offers support for Ethernet networking, as well as two CAN FD controllers, which conform to the CAN 2.0 standard. An integrated external memory controller, Quad SPI interface, TFT-LCD controller and a high-performance architecture provide users of the LPC546xx MCU family with the capability to implement cost-effective new display solutions.

The LPC546xx MCU family is particularly effective when used in applications that require data aggregation from several different inputs. The MCUs provide a variety of wake- up sources, including NXP’s FlexComm peripherals.

DSP capabilities enable LPC546xx MCUs to support complex algorithms in data- intensive applications. Flash options support large, flexible internal and external memory configurations.

The LPC546xx MCUs are compatible with other devices in the LPC54000 series, which means that the LPC546xx family provides a seamless migration path for users of LPC54000 devices to increase processing power and add advanced peripherals.
