描述 Description

The SNC7320 Series, a high performance and low power architecture, has two 32-bitARM Cortex-M3processors as the core operating at a frequency of up to 198 MHz. The dual processorscan be programmed to function independently or as a master processor and a co-processor.The SNC7320 Series offers a wide range of peripherals to provide flexibilityfor designs of variousapplications including I2C, UART, SPI, RTC, WDT, SAR-ADC, SF controller, USBdevice. Furthermore, the SNC7320 Series embedded audio device.There are three power saving modes forthe SNC7320 Series, sleep, deep sleep, and deep power-down.The software development (SDK) of the SNC7320 Series includes various samplecodes that complywith the Keil? MDK-ARM? compiler. Development, programming and debugging canbe implementedefficiently in the Keil MDK-ARM environment.
