描述 Description

The SNC7330 series has two 32-bit ARM? Cortex?-M3 processors in symmetric dual-corearchitecture. Each of the two cores controls respective designated peripherals, cooperateswith the other, and can be independently programmed. The two processors of the SNC7330series operate at a frequency of up to 96 MHz individually. Supporting RAM array withdata bandwidth of up to 5 GB/sec and deep power-down mode consuming less than 1 μA,the SNC7330 series is designed for high performance and low power consumption embeddedapplications.The SNC7330 series offers standard peripherals including SAR ADC, SPI, UART,USB device, I2C, SD/SDIO controller, and up to three I2S controllers. With the softwaredevelopment kit (SDK) that includes various sample codes complying with the Keil?MDK-ARM? compiler, development, programming, and debugging can be implemented efficientlyfor various consumer electronics applications.
