New Product Introduction

NPI Body

NXP Semiconductors LPC553x/S3x

Arm® Cortex®-M33 MCU bringing new levels of analog integration and high system reliability to the LPC5500 series

The LPC553x/S3x MCU family further expands the world’s first general purpose Cortex-M33-based MCU series, offering significant performance enhancement, all on-chip RAM with Parity or ECC, renewed security features and precision analog additions, leveraging the cost-effective 40-nm NVM process technology.

The LPC553x/S3x family includes a proprietary DSP accelerator offering 10x clock cycle reduction, bringing significant signal processing efficiency gains.

The LPC553x/S3x MCU family will be launched in two phases, launch of the LPC55S3x series and EVK will be in Q4 2022.
