Figure 13. TMS320 Interface
If there is no need to have more than one device on the serial bus, then CS can be tied low. Figure 14 shows
an example of how to connect the TLV5636 to TMS320, SPI
or Microwire
using only three pins.

Notes on SPI
and Microwire
: Before the controller starts the data transfer, the software has to generate a
falling edge on the I/O pin connected to FS. If the word width is 8 bits (SPI
and Microwire
), two write
operations must be performed to program the TLV5636. After the write operation(s), the DAC output is updated
automatically on the 16
th
positive clock edge.
serial clock frequency and update rate
The maximum serial clock frequency is given by:

Note that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
TLV5636 has to be considered, too.
