It has I2S interface for the audio data transmission and I2C interface for itself configuration. The I2C address is 0x0A. It offers the unique ability to independently program the ADC and DAC sample rates from a single clock source. The respective sample rates from the clock source are on signals ADCLRC and DACLRC. There is only one frame clock source on MCU, so the ADCLRC and DACLRC are connected together with the I2SWS signal. Note, the I2S interface of S6E1B8 series MCU only have master mode, which means the clock will derive from MCU to codec as an external clock of it. The 12.288MHz crystal, and two 22pF capacitors will not been mounted when assembly.

The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further uses common mode cancellation to decrease errors from process variation, temperature, and environmental stress. This sensor communicates with MCU via I2C interface. The address of this device is 0x0E which is configured by the ADDR pin. An interrupt will occur once the data updated. Figure 4-6: Acceleration Sensor 4.4 USB Connector CN4 is a micro-B connector that interfaces to the USB0 peripheral of the S6E1B8 device to enable development of USB device applications. Transistor MMC8550 is used to force a termination of the USB communications.
