The XR32F429 devices are based on the high-performance ARM Cortex-M4F 32-bit RISC core operating at frequency up to 192MHz. The Cortex-M4F core features a Floating Point Unit (FPU) single precision which all ARM single-precision data-processing instructions and data types. It also implements a memory protection unit (MPU) which enables application security. It supports an 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.
