Functional Description
The MM5452 is specifically designed to operate 4
(/2
-digit 7-
segment displays with minimal interface with the display and
the data source. Serial data transfer from the data source to
the display driver is accomplished with 2 signals, serial data
and clock. Since the MM5452 does not contain a character
generator, the formatting of the segment information must
be done prior to inputting the data to the MM5452. Using a
format of a leading ‘‘1’’ followed by the 32 data bits allows
data transfer without an additional load signal. The 32 data
bits are latched after the 36th clock is complete, thus pro-
viding non-multiplexed, direct drive to the display. Outputs
change only if the serial data bits differ from the previous
time.
A block diagram is shown in Figure 1. For the MM5452 a
DATA ENABLE is used instead of the 33rd output. If the
DATA ENABLE signal is not required, the 33rd output can
be brought out. This is the MM5453 device.
