TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC T6963C 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. Features (cid:122) Display format (pin−selectable) Weight: 1.2 g (typ.) Columns Lines The combination of number of columns and number of lines must not cause the frequency to exceed 5.5 MHz. (See Fig. 2) : 32, 40, 64, 80 : 2, 4, 6, 8, 10, 12, 14, 16, 20, 24, 28, 32 (cid:122) Character font (pinselectable) Horizontal dots Vertical dots 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. : 5, 6, 7, 8 : 8 (fixed) (cid:122) Display duty (cid:122) A 128−word character generator ROM (code 0101) T6963C−0101 is built in as standard. (cid:122) External display memory : 64 KB Max : 1 / 16 to 1 / 128 The addresses in display memory of the text area, graphic area and external character generator area are determined by software. (cid:122) Read or Write operations from the CPU do not disturb the display. (cid:122) 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 : 900 kΩ (typ.) Built−in feedback resistor (cid:122) Toshiba LCD driver LSIs (other than these with a built−in RAM) can be connected to the device. (cid:122) External display RAM must be static RAM. The T6963C cannot refresh D−RAM. (cid:122) The attribute functions can only be used in Text mode. They cannot be used in Graphic or Combination Character mode. 1 2003-06-18 Block Diagram T6963C 2 2003-06-18 Pin Assignment T6963C Pin Functions Pin Name I / O Functions MDS MD0 MD1 Input Pins for selection of LCD size DUAL H H H L H H 2 L MDS L MD1 H MD0 LINES 6 V−DOTS 16 32 48 L H L 4 H L L L 8 64 H H H H 10 80 H H H L H L H 14 H L L 16 L H H H H L 12 4 96 112 128 32 L L H L 8 64 L L L L L L L L L H H L H H H H H L L L L L H H 12 16 20 24 28 32 96 128 160 192 224 256 1 SCREEN 2 SCREENS MD2 MD3 FS0 FS1 Input Pins for selection of number of columns Input Pins for selection of font MD2 MD3 Columns H H 32 L H 40 H L 64 L L 80 FS0 FS1 Font L H H H L L 5 × 8 6 × 8 7 × 8 8 × 8 H L D0 to D7 I / O Data I / O pins between CPU and T6963C (D7 is MSB) WR RD CE Input Input Input Data Write.

RESET is kept L between 5 clocks up (oscillation clock). ● When HALT = L, the oscillation stops. The power supply for the LCD must now be turned off, to protect the LCD from DC bias. ● The HALT function includes the RESET function. ● The column / line counter and display register are cleared by RESET. (Other registers are not cleared.) Disable the display using the clear−display register. ● The status must be checked before data or commands are sent. The MSB = 0 status check must be done in particular. There is a possibility of erroneous operation due to a hard interrupt. ● STA0 and STA1 must be checked at the same time. When a command is executed, data transmission errors ● The character codes used by the T6963C are different from ASCII codes. ● The T6963C can only handle one byte per machine cycle (16 clocks). It is impossible to send more than two ● When using a command with operand data, it important to send the data first, and then execute the may occur. command. data in a machine cycle. 5 2003-06-18
