The SNC7320 Series, a high performance and low power architecture, has two 32-bit ARM Cortex-M3
processors as the core operating at a frequency of up to 198 MHz. The dual processors can 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 flexibility for designs of various
applications including I2C, UART, SPI, RTC, WDT, SAR-ADC, SF controller, SD/SDIO, NAND flash
controller, USB host and device. Furthermore, the SNC7320 Series provides five I 2S controllers for
external audio device connections. There are three power saving modes for the SNC7320 Series, sleep,
deep sleep, and deep power-down.
The software development (SDK) of the SNC7320 Series includes various sample codes that comply with
the Keil® MDK-ARM® compiler. Development, programming and debugging can be implemented
efficiently in the Keil MDK-ARM environment.
