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.
