A Single -Chip Computer Audio Code Of Cortex -M0+ -CJC2100

The USBCodeC chip can process digital audio signals, such as increasing volume, balanced adjustment, and sound processing.These processes can be achieved through the control button of the headset, allowing users to adjust the audio effect according to their preferences.The USBCodeC chip can also control the level of noise and distortion to provide high -quality audio output.Noise refers to the murmur or static sound in the audio signal, and distortion refers to the incorrect deformation that occurs during the transmission process.

Domestic USBCODEC chip represented by Gongcai.com -CJC2100 is a Cortex -M0+Single -chip machine, Designed for USB headset devices.It integrates a 32 -bit RISC  CPUAnd 8kb SRAM, USB, UART, IIC, Audio Code, GPIO, timer, WDT, PWM, SPI, IIS, SPDI, PDM, SARADC, PLL, LDO, etc.

CJC2100 can start through the external flash through the SPI interface.After booting, the program is read from the external flash memory to the internal SRAM for execution.

The CJC2100 can run to 48MHz. Its design is particularly careful to use less power consumption, and at the same time allows flexibility to achieve high performance.It includes clock door control for a single IP. The CJC2100 can further operate in different energy -saving modes: normal, free, standby, shutdown, different modes have different clocks and power strategies.

CJC2100 chip integrates 2 AHB bus and 1 APB (compatible with AMBA protocol).CPU core is used as AHB's main operation in a AHB bus, DMAControllerAs the main operation of AHB on other AHB bus.A AHB2APB bridge is used for peripheral configuration.

CJC2100 integrates 1KB guidance ROM.When ISP is available, the CPU guides ROM from the inside, receiving program code from UART bus, and stored in external flash memory.If the normal mode is enabled, the CPU guides ROM from the inside, obtains program code from the external SPI flash memory, and is stored in the internal SRAM, and then re -mapMemoryConfiguration, guide from the internal SRAM.
