NXP Semiconductors LPC55S1x/LPC551x Microcontrollers (MCUs)

NXP Semiconductors LPC55S1x and LPC551x Microcontrollers (MCUs) are 32-bit Arm® Cortex®-M33 based modules designed for general-purpose embedded applications. The Arm Cortex-M33 CPU architecture features 150MHz frequency and provides a security foundation with isolation to protect valuable IP and data with TrustZone® technology. This simplifies the design and software development of digital signal control systems with integrated digital signal processing (DSP) instructions. NXP LPC55S1x and LPC551x MCUs also offer support for secure boot, HASH, AES, RSA, UUID, dynamic encrypt and decrypt, debug authentication, and TBSA compliance. Typical applications include industrial IoT, industrial automation, building control, diagnostic equipment, and consumer electronics.
