Serial Control
Figure 6 shows conversion from a three-wire serial interface,
such as used by the Cirrus Logic CL-PD6730, to the standard
eight-line parallel interface used by the MIC2563A-1. This
interface requires three common, low cost 7400-series logic
ICs:
Either 3.3V or 5V logic devices may be used, depending upon
the control voltage employed by the slot logic controller. Pin
numbers in parenthesis refer to the MIC2563A-1BSM. Gerber
files for this PC board layout are available to Micrel custom-
ers. Please contact Micrel directly.
Another serial-to-parallel solution for this application is the
74HC594, 8-bit shift register with output registers. This de-
vice contains the eight D flip-flops plus has latched outputs
suitable for this purpose.
