APPLICATION INFORMATION
TLV5616 interfaced to MCS51
microcontroller
hardware interfacing
Figure 18 shows an example of how to connect the TLV5616 to an MCS51
compatible microcontroller. The
serial DAC input data and external control signals are sent via I/O port 3 of the controller. The serial data is sent
on the RxD line, with the serial clock output on the TxD line. P3.4 and P3.5 are configured as outputs to provide
the chip select and frame sync signals for the TLV5616.

Controller Interface
software
The example program puts out a sine wave on the OUT pin.
The on-chip timer is used to generate interrupts at a fixed frequency. The related interrupt service routine fetches
and writes the next sample to the DAC. The samples are stored in a lookup table, which describes one full period
of a sine wave.
The serial port of the controller is used in mode 0, which transmits 8 bits of data on RxD, accompanied by a
synchronous clock on TxD. Two writes concatenated together are required to write a complete word to the
TLV5616. The CS and FS signals are provided in the required fashion through control of I/O port 3, which has
bit addressable outputs.
