T6963CFG CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC / Integrated Circuit IC Original and New

Discription:

The T6963CFG 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.
The T6963CFG is lead (Pb)-free (Sn-Ag) product

Features:

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)
z Character font (pin−selectable)
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.
z Display duty : 1 / 16 to 1 / 128
z A 128−word character generator ROM (code 0101) T6963CFG−0101 is built in as standard.
z 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.
z Read or Write operations from the CPU do not disturb the display.

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 k ohms (typ.)
z Toshiba LCD driver LSIs (other than these with a built−in RAM) can be connected to the device.
z External display RAM must be static RAM. The T6963CFG cannot refresh D−RAM.
z The attribute functions can only be used in Text mode. They cannot be used in Graphic or Combination
