NXP Semiconductors LPC550x/S0x Microcontrollers

NXP Semiconductors LPC550x/S0x Microcontrollers offer advanced security, making them ideal for industrial, IoT, and general embedded applications. These Arm® Cortex®-M33-based microcontrollers feature a CASPER Crypto engine with up to 256KB on-chip flash and up to 96KB of on-chip SRAM. These microcontrollers also include a PRINCE module for on-the-fly flash encryption/decryption. The series includes many timers, including a code watchdog, CAN FD, five general-purpose timers, an SCTimer/PWM, an RTC/alarm timer, a 24-bit multi-rate timer (MRT), and a windowed watchdog timer (WWDT). Also provided are many flexible serial communication peripherals, a programmable logic unit (PLU), and a 16-bit 2.0 Msamples/sec ADC capable of simultaneous conversions, comparator, and temperature sensors.

NXP LPC550x/S0x Microcontrollers provide a security foundation, offering isolation to protect IP and data with TrustZone^® technology. The integrated digital signal processing (DSP) instructions simplify the design and software development of digital signal control systems. The LPC550x/S0x modules also support security requirements for secure boot, HASH, AES, RSA, UUID, dynamic encrypt and decrypt, debug authentication, and TBSA compliance.
