www.DataSheet4U.com T6963CFG TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC T6963CFG DOT MATRIX LCD CONTROLLER LSI 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 Weight: 1.2 g (typ.) z 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. z 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.) 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 Character mode. 1 2007-05-15 www.DataSheet4U.com T6963CFG Block Diagram 2 2007-05-15 www.DataSheet4U.com T6963CFG Pin Assignment Pin Functions Pin Name I/O Pins for selection of LCD size DUAL Functions H L H H 2 16 H L H L 4 32 H L L H 6 48 H L L L 8 64 H H H H 10 80 H H H L 12 96 H H L H 14 H H L L 16 L L H H 4 32 L L H L 8 64 L L L H 12 96 L L L L 16 L H H H 20 L H H L 24 L H L H 28 L H L L 32 MDS MDS MD0 MD1 Input MD1 MD0 LINES V−DOTS 112 128 128 160 192 224 256 2 SCREENS 1 SCREEN MD2 MD2 MD3 Input Pins for selection of number of columns MD3 Columns FS0 FS0 FS1 Input Pins for selection of font FS1 Font D0 to D7 I/O Input Data I / O pins between CPU and T6963CFG (D7 is MSB) Data Write.
