General description
The LPC55S6x is an ARM Cortex-M33 based microcontroller for embedded applications.
These devices include an ARM Cortex-M33 coprocessor, CASPER Crypto/FFT engine,
PowerQuad hardware accelerator for DSP functions, up to 320 KB of on-chip SRAM, up
to 640 KB on-chip flash, PRINCE module for on-the-fly flash encryption/decryption,
high-speed and full-speed USB host and device interface with crystal-less operation for
full-speed, SD/MMC/SDIO interface, 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 1.0 Msamples/sec ADC, 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 LPC55S6x also offers support
for secure boot, HASH, AES, RSA, UUID, dynamic encrypt and decrypt, debug
authentication, and TBSA compliance.
