Figure 22. Interfacing The TLC5618A to the TMS320C203 DSP
general serial interface
Both the TLC5618 and TLC5618A are compatible with SPI, QSPI, or Microwire serial standards. The hardware
connections are shown in Figures 23 and 24. The TLC5618A has an internal state machine that will count 16
clocks after the falling edge of CS and then internally disable the device. The internal edge is ORed together
with CS so that the rising edge can be provided to CS prior to the occurrence of the internal edge to also disable
the device.
The SPI and Microwire interfaces transfer data in 8-bit bytes, therefore, two write cycles are required to input
data to the DAC. The QSPI interface, which has a variable input data length from 8 to 16 bits, can load the DAC
input register in one write cycle.
