CJC6811A Cortex-M0+ based MCU,designedfor USB Headphone Appliances
CJC6811 is a Cortex-M0+ based MCU, designed for USB headphone appliances.It integrates one 32-bit RISC CPU with 16KB SRAM, USB, UART, IIC, audio codec,GPIO, TIMER, WDT, PWM, SPI, IIS, SPDIF, PDM, SARADC, PLL, LDO etc.CJC6811 can boot from external flash through SPI interface. After powered on, theprogram is read from external flash into internal SRAM for execution.The CJC6811 can run up to 48MHz, and it is designed with special care to minimizethe power consumption while allowing for the flexibility to reach for highperformance. It includes the clock gating for individual IP, and CJC6811 can befurther operated under different power-saving modes: Normal, Idle, Standby,Power-down, different mode have different clock and power strategy.
