Product data sheet
1. General description
The LPC55S0x/LPC550x is an ARM Cortex-M33 based microcontroller for embedded
applications. These devices include CASPER Crypto engine, up to 256 KB on-chip flash,
up to 96 KB of on-chip SRAM, PRINCE module for on-the-fly flash encryption/decryption,
Code Watchdog, CAN FD, five general-purpose timers, one SCTimer/PWM, one
RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Windowed Watchdog Timer
(WWDT), nine flexible serial communication peripherals (which can be configured as a
USART, SPI, high speed SPI, I2C, or I2S interface), Programmable Logic Unit (PLU), one
16-bit 2.0 Msamples/sec ADC capable of simultaneous conversions, comparator, and
temperature sensor.
The ARM Cortex-M33 provides a security foundation, offering isolation to protect valuable
IP and data with TrustZone® technology. It simplifies the design and software
development of digital signal control systems with the integrated digital signal processing
(DSP) instructions. To support security requirements, the LPC55S0x/LPC550x also offers
support for secure boot, HASH, AES, RSA, UUID, DICE, dynamic encrypt and decrypt,
debug authentication, and TBSA compliance.
