About XR32F429

The XR32F429 is based on the high-performance ARM Cortex-M4F 32-bit RISC core clocked at up to 192MHz. The Cortex-M4F core has a floating point unit (FPU) single precision, which contains all ARM single precision data processing instructions and data types. It also implements a Memory Protection Unit (MPU) for application security. It supports integrated 832KB SRAM and 2MB flash ROM. It also includes many peripherals, including UART, TWI, SPI, I2S, DMIC, PWM, IrDA (T/R), CSI, SDIO, and auxiliary ADC.
