The LPC551x/S1x MCU family expands the world’s first general purpose Cortex-M33-based MCU series, offering
significant advantages for developers, including pin-, software- and
peripheral-compatibility for ease of use and to accelerate time to market, while leveraging the cost-effective 40-nm
NVM process technology.
The LPC551x/S1x is the baseline family within the LPC5500 MCU series, providing new levels of cost and performance
efficiency in addition to advanced security and system integration for industrial and general
