  • 32µA/MHz for leading performance efficiency
  • 10x improvement in signal processing
  • Rich integration to secure, sense and connect
  • MCUXpresso Ecosystem with HW & SW scalability

The LPC55S6x MCU family builds on the Cortex-M33 introduced with the LPC5500 series. This family leverages the Armv8-M to introduce new levels of performance and advanced security, bringing significant signal processing efficiency gains from a DSP accelerator offering a 10x clock cycle reduction. An optional second core offers balance in performance and power efficiency.

In addition, the 40nm NVM based process technology brings cost advantages, broad scalable packages, and memory options; as well as a robust enablement including MCUXpresso and Tools ecosystem, and low-cost development boards.
