SERIAL DATA INTERFACE
The DAC8814 uses a 3-wire (CS, SDI, CLK) SPI-compatible serial data interface. Serial data of the DAC8814 is
clocked into the serial input register in an 16-bit data-word format. MSB bits are loaded first. Table 2 defines the
16 data-word bits for the DAC8814.
DAC8814
SBAS338–JANUARY 2005
Figure 56. System Level Digital Interfacing
Data is placed on the SDI pin, and clocked into the register on the positive clock edge of CLK subject to the data
setup and data hold time requirements specified in the Interface Timing Specifications. Data can only be clocked
in while the CS chip select pin is active low. For the DAC8814, only the last 16 bits clocked into the serial register
are interrogated when the CS pin returns to the logic high state.
Since most microcontrollers output serial data in 8-bit bytes, three right-justified data bytes can be written to the
DAC8814. Keeping the CS line low between the first, second, and third byte transfers results in a successful
serial register update. Similarly, two right-justified data bytes can be written to the DAC8814. Keeping the CS line
low between the first and second byte transfer will result in a successful serial register update.
