MCU Series
LPC552x MCU Family
Building on the LPC55S6x MCU family, LPC552x MCUs bring to market advanced
energy efficiency and real-time performance with embedded security and protection,
leveraging NXP’s cost effective 40-nm embedded flash technology.
OVERVIEW
The LPC552x MCU family expands on the world’s first general
purpose Arm Cortex-M33-based microcontroller introduced
with the LPC5500 series. This mainstream family provides a
perfect balance between security, performance efficiency and
system integration for the general embedded and industrial
IoT markets. The LPC552x MCU family combines the high
performance efficiency of the Cortex-M33 core with multiple
high-speed interfaces, an integrated power management IC,
and rich analog integration.
The LPC5500 MCU series offers significant advantages for
developers, including cost-effective 40-nm NVM process
technology, along with pin-, software- and peripheralcompatibility for ease of use and accelerating time to
market. This series is supported by NXP’s comprehensive
enablement package, including MCUXpresso software and
tools along with low-cost development boards.

HIGH INTEGRATION AND ADVANCED SECURITY
COMPREHENSIVE ENABLEMENT SOLUTIONS
The LPC552x MCU family offers the right combination of
feature integration, low power consumption and security
capabilities. With multiple connectivity options including highspeed USB with on-chip PHY, high-speed SPI, SDIO and the
popular FlexComm interfaces (configurable as either SPI/I2C/
I2S,UART) this MCU family features a versatile integration for
today’s demanding applications. The security capabilities of
the LPC552x MCU family include SRAM PUF for root of trust
and provisioning, a hardware symmetric encryption/decryption
engine, secure debug and the PRINCE engine for real-time
execution from encrypted images.
