TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
T6963C
DOT MATRIX LCD CONTROLLER LSI
The T6963C is an LCD controller designed to be used with LCD
control driver LSIs and data display memories. The device has an
8−bit parallel data bus and control lines for reading or writing
through an MPU interface. It can be directly connected to a
TMPZ−80.
It has a 128−word character generator ROM which can control an
external display RAM of up to 64 Kbytes. Allocation of text,
graphics and external character generator RAM can be made
easily and the display window can be moved freely within the
allocated memory range.
The device supports a very broad range of LCD formats by
allowing selection of different combinations via a set of
programmable inputs. It can be used in text, graphic and
combination text−and−graphic modes, and includes various
attribute functions.
Weight: 1.2 g (typ.)
Features
l Display format (pin−selectable)
Columns
: 32, 40, 64, 80
Lines
: 2, 4, 6, 8, 10, 12, 14, 16, 20, 24, 28, 32
The combination of number of columns and number of lines must not cause the frequency to exceed 5.5 MHz.
(See Fig. 2)
l Character font (pinselectable)
Horizontal dots
: 5, 6, 7, 8
Vertical dots
: 8 (fixed)
It is necessary to set a character font in Graphic mode just as in Text mode. The oscillation frequency does not
change with the font selection.
l Display duty
: 1 / 16 to 1 / 128
l A 128−word character generator ROM (code 0101) T6963C−0101 is built in as standard.
l External display memory : 64 KB Max
The addresses in display memory of the text area, graphic area and external character generator area are
determined by software.
l Read or Write operations from the CPU do not disturb the display.
l A crystal oscillator circuit is built in. The oscillation frequency is adjusted according to the display size. If using
an external clock, use the XI pin as the clock input. (XO open.)
External capacitors Crystal oscillation : 20 to 30 pF
Ceramic oscillation : 30 to 100 pF
Built−in feedback resistor
: 900 kΩ (typ.)
l Toshiba LCD driver LSIs (other than these with a built−in RAM) can be connected to the device.
l External display RAM must be static RAM. The T6963C cannot refresh D−RAM.
l The attribute functions can only be used in Text mode. They cannot be used in Graphic or Combination
Character mode.

● The relationship between number of row / column and oscillation clock (Fig. 2)
The frequency of the crystal oscillator is adjusted by the following formula.
fOSC : Frequency of oscillation
fSCP : Frequency of shift clock (fSCP = fOSC / 2)
fR : Frequency of Frame
M : Number of characters on one line (number of dots on one line 8 M)
For all font sizes (e.g. 7 × 8, 6 × 8, 5× 8) the oscillation frequency remains constant.
N : Number of rows (duty = 1 / 8N)
