CONDITION 2: CLK IS TERMINATED AT THE “HIGH” LEVEL
Notes:
1. Address: 41H
2. D1 to D156 = Display Data
When D1 to D156 are set to “1”, Display is turned ON.
When D1 to D156 are set to “0”, Display is turned OFF.
3. DR = 1/2 Bias Drive or 1/3 Bias Drive Switching Control Data
4. SC = Segment ON/OFF Control Data
5. BU = Normal Mode/Power-Saving Control Data
6. x = Not Relevant
For example, there are 63 segments that are being used, the 63 bits of display data (D94 to D156)
must be sent. Please refer to the diagram below.

CONTROL DATA
DR: 1/2 BIAS DRIVE OR 1/3 BIAS DRIVE SWITCHING CONTROL DATA.
DR is the 1/2 bias drive or 1/3 bias drive switching control data bit. It is used to select either 1/2 bias
drive or 1/3 bias drive. When this pin is set to “0” the 1/2 bias drive is selected. When this pin is set to “1’,
the 1/3 bias drive is selected. Please refer to the table below for the DR settings.
DR
“0”
“1”
Drive Type
1/2 Bias Drive
1/3 Bias Drive
SC: SEGMENT ON/OFF CONTROL DATA
SC is the Segment ON/OFF Control Data Bit. It is used to select the state of the segments. If the SC is
set to “0”, then the Segment Display are turned ON, however, if the SC is set to “1”, the Display State is
OFF. Please refer to the table below.
SC Display State
“0”
“1”
ON
OFF
It should be noted that when the segments are turned off via the SC setting (SC=”1”), the segments are
turned off the outputting of the segment OFF waveforms from the Segment Output Pins.
BU: NORMAL MODE/POWER SAVING MODE CONTROL DATA BIT
BU is the Normal Mode/Power Saving Mode Control Data Bit. It is used to select either the Normal
Mode or the Power saving Mode. When the BU is set to “0”, the Normal Mode is enabled, however, if
the BU is set to “1”, the Power saving Mode is active. It should be noted that under the Power Saving
Mode, the Oscillation (OSC Pin) is stopped and the Common and Segment Pins output Vss levels.

/INH AND DISPLAY CONTROL
When power is first applied, the PT6523 internal data are not defined (D1 to D156, DR, SC and BU).
The display is turned off (SG1 to SG52, COM1 to COM3 are all set to “Low” Level) by setting the /INH
pin to “Low” at the same time the power is applied. (Please note that when the /INH Pin is set to “LOW”,
the OSC Pin is not active.) As a result of this, irrelevant display at the time of the power ON can be
eliminated if not prevented by transferring the serial data from the controller while the display is OFF
and by setting the /INH pin after the transfer is completed. Please refer to figures below.

Notes:
1. All dimensioning and tolerancing conform to ASME Y14.5M - 1994.
2. Datums A-B and D to be determined at datum plane H.
3. Dimensions D1 and E1 do not include mold prortrusion. Allowable protrusion is 0.25mm per side.
Dimensions D1 and E1 do include mold mismatch and are determined at the datum plane H.
4. Controlling Dimension: MILLIMETERS.
5. Dimension b does not include dambar protrusion. The dambar protrusion (s) shall not cause the
lead width to exceed b maximum by more than 0.08 mm. Dambar cannot be located on the lower
radius or the lead foot. minimum space between protrusion and as adjacent lead is 0.07 mm for
0.4mm and 0.5mm pitch packages.
6. A1 is defined as the distance from the seating plane to the lowest point of the package body.
7. Refer to JEDEC MS-026 Variation BCD.
JEDEC is the TRADEMARK OF JEDEC SOLID STATE TECHNOLOGY ASSOCIATION.
