NXP LPC552x MCU Series Fact Sheet
Built on the LPC55S6x MCU series, the LPC552x MCU utilizes NXP's cost-effective 40nm embedded Flash technology to deliver advanced energy efficiency and real-time performance with embedded security and protection.
Overview
The LPC552x MCU series extends the world's first Arm Cortex-M33-based general-purpose microcontroller, the LPC5500 series. This mainstream series strikes a perfect balance between general embedded and industrial IoT markets, as well as security, performance efficiency, and system integration. The LPC552x MCU series combines the high performance of the Cortex-M33 core with multiple high-speed interfaces, integrated power management ICs, and rich analog integration.
The LPC5500 MCU series offers significant advantages for developers, including the cost-effective 40nm NVM process technology, and high compatibility in pinouts, software, and peripherals for ease of use and shorter time-to-market. The series is supported by NXP's comprehensive enablement kit, including MCUXpresso software and tools, and low-cost development boards.
