ETC HI-8020SM-63

HI-8020 Series
September 1999
GENERAL DESCRIPTION
The HI-8020 high voltage display driver is a
functional replacement for the AMI S5420 and
Micrel MIC8013/8014 series. This CMOS product
is designed to drive liquid crystal displays by
converting 5 volt serial data to parallel segment
and backplane waveforms with amplitudes up to
30 volts. The HI-8020 differs from the HI-8010 by
only the shift register clock logic gating with chip
select.
The chip can drive up to 38 segments and has 4
possible shift register data taps to provide options
to cascade devices for larger displays. Data is
clocked into a 38 stage shift register and parallel
latched before the output translators by a Load
input.
The HI-8020 is available in a variety of ceramic and
plastic packaging including DIP; leaded and
leadless chip carriers; and J-lead and gull-wing
quad flat packs.

INTERNAL OSCILLATOR CIRCUIT
FUNCTIONAL DESCRIPTION
Whenever a Logic "0" is applied to the Chip Select (CS)
input, one bit of data is clocked into the shift register with
each negative transition of the Clock (CL) input. CS is
internally tied to VSS on some versions. A Logic "1" present
at the Load (LD) input will cause a parallel transfer of data
from the shift register to the data latch. If the Load (LD) input
is held high while data is clocked into the shift register, the
latch will be transparent.
C
To display segments, a Logic "1" is stored in the appropriate
shift register bit position, and the segment output is out-ofphase with the backplane.
The backplane output functions in 1 of 2 modes; externally
driven or self-oscillating. When the LCDØ input is externally
driven with the LCDØ OPT input open circuit (Figure 2), the
backplane output will be in-phase with LCDØ. Utilizing the
self-oscillating mode, inputs LCDØ and LCDØ OPT are tied
together and connected to an RC circuit (Figure 3).
A 150KW resistor with a 470pF capacitor generates an
approximate backplane frequency of 100Hz.
The
LCDØ/LCDØ OPT oscillator frequency is divided by 256 to
determine the backplane output frequency.

AND DRIVER
For displays having a number of segments greater that 38,
two or more of the display drivers may be cascaded together
by connecting the serial data output (DOUT) from the first
driver, to the serial data input (DIN) of the following driver,
etc. Data out (DOUT) will change state on the rising edge of
the Clock (CL). Clock (CL), Load (LD) and Chip Select (CS)
should be tied in common with each other, respectively,
between all cascaded display drivers.
