DESCRIPTION
The SCE574x is a four digit, dot addressable 5 x 7 dot
matrix, serial input, alphanumeric Intelligent Display
device. The four digits are packaged in a rugged, high
quality, optically transparent, plastic 14
pin DIP with
2.54
mm (0.1") pin spacing.
The SCE574xP is a SIP version of SCE574x. The
SCE574xQ is also a SIP version of the SCE574x but the
leads are at right angles to the package so that the part
can be mounted vertically. The SIP version parts have
only 7
pins. The SIP parts do not have the option of using
an external clock. All the electrical descriptions for the
SCE574x apply to the SIP versions except the allusions
to the external clock.
The on-Board CMOS has a 140 bit RAM, one bit associ-
ated with one LED, each to generate User Defined Char-
acters. In Power Down Mode, quiescent current
is
< 50 µA.
The SCE574x is designed for work with the serial port of
most common microprocessors. Data is transferred into
the display through the Serial Data Input (DATA), clocked
by the Serial Data Clock (SDCLK), and enabled by the
Load Input (LOAD).
The SCE574x Clock I/O (Clk I/O) and Clock Select (CLK-
SEL) pins offer the user the capability to supply a high
speed external multiplex clock. This feature can minimize
audio in-band interference for portable communication
equipment or eliminate the visual synchronization effects
found in high vibration environments such as avionic
equipment.
A divide by 16 prescalar is built into the part and can be
accessed by software to reduce the multiplex frequency if
a high speed external clock is used.
