Pin Configuration Table 5. Pin Function Descriptions Pin No.MnemonicType1Description 1 SCLK I Serial Clock. SCLK provides the serial clock for accessing data from the part and writing serial data to the control registers. 2 DOUT O Data Out. The data on this pin represents data being read from the control registers and is clocked out on the falling edge of the SCLK. 3 DIN I Data In. Data written to the control registers is provided on this input and is clocked in on the rising edge of the SCLK. 4 CS I Chip Select, Active Low. This input frames the serial data transfer. 5, 6 DIO0, DIO1 I/O Multifunction Digital I/O Pins. 7, 11 NC – No Connect. 8, 10 AUX COM S Auxiliary Grounds. Connect to GND for proper operation. 9 RST I Reset, Active Low. This input resets the embedded microcontroller to a known state. 12 AUX DAC O Auxiliary DAC Analog Voltage Output. 13 VDD S +3.3 V Power Supply. 14 AUX ADC I Auxiliary ADC Analog Input Voltage. 15 VREF O Precision Reference Output. 16 COM S Common. Reference point for all circuitry in the ADIS16201. 1 S = Supply; O = Output; I = Input. Rev.
