NXP LPC550x/S0x MCU Family

Market's Lowest Cost Arm Cortex-M33 MCU

The baseline NXP LPC550x/S0x MCU family, with lower cost options and a smaller footprint, further expands the existing general-purpose LPC5500 MCU series. The microcontroller group features advanced security and safety integration that offer industrial, IoT and embedded applications an extra level of protection.

Offering excellent ecosystem advantages for developers, including pin, software and peripheral compatibility in addition to a comprehensive portfolio of software and tools, the NXP LPC550x/S0x MCU family helps accelerate time to market.

The LPC5500 MCU Series leverages the Arm® Cortex®-M33 technology, combining significant product architecture enhancements and greater integration over previous generations; offering dramatic power consumption improvements and advanced security features including SRAM PUF based root of trust and provisioning, real-time execution from encrypted images (internal flash), and asset protection with Arm TrustZone®-M.

In addition, the LPC5500 microcontroller series provides a comprehensive offering and several scalability options, all of which benefit from 40-nm cost advantages, broad scalable packages and memory options, as well as a robust enablement including the MCUXpresso Software and Tools ecosystem and low-cost development boards.
