The LPC55S6x is an Arm Cortex®-M33 based micro-controller for embedded applications. These devices include up to 320 kB of on-chip SRAM, up to 640 kB on-chip flash, high-speed and full-speed USB host and device interface with crystal-less operation for full-speed, one 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), one high speed SPI (50MHz), eight flexible serial communication peripherals (each of which can be a USART, SPI, I2C, or I2S interface), one 16-bit 1.0 Msamples/sec ADC, 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 HASH, AES, RSA, UUID, dynamic encrypt and decrypt, debug authentication, and TBSA compliance.
