T6963CFG 2007-05-15 1 toshiba cmos digital integrat ed 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 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 li nes must not cause the freq uency 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 os cillation 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, gr aphic area and external character generator area are determined by software. z read or write operations from th e 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 pi n 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 ? (typ.) z toshiba lcd driver lsis (oth er 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 mo de. they cannot be used in graphic or combination character mode. weight: 1.2 g (typ.)

T6963CFG 2007-05-15 5 functional definition after power on, it is necessary to reset. 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 erro neous operation due to a hard interrupt. sta0 and sta1 must be checked at the same time. when a command is executed, data transmission errors may occur. the T6963CFG can only handle one byte per machine cycle (16 clocks). it is impossible to send more than two data in a machine cycle. when using a command with operand data, it importan t to send the data firs t, and then execute the command. the character codes used by the T6963CFG are different from ascii codes.

note 4: when using the msb = 0 command, a status read must be performed. if a status check is not carried out, the T6963CFG cannot operate normally, even after a delay time. the hardware interrupt occurs during the addre ss calculation period (at the end of each line). if a msb = 0 command is sent to the T6963CFG dur ing this period, the T6963CFG enters wait status. if a status check is not carried out in this st ate before the next command is sent, there is the possibility that the command or data will not be received.

(example) note: attribute functions can only be applied to text displa y, since the attribute data is placed in the graphic ram area.
T6963CFG 2007-05-15 19 "uusjcvufgvodujpo the attribute operations are reverse di splay, character blink and inhibit. the attribute data is written into the graphic area which was defined by the set contro l word command. only text display is possible in attribute function mode; graphic display is automati cally disabled. however, the display mode command must be used to turn both text and graphic on in order for the attribute f unction to be available. the attribute data for each character in the text area is written to the same address in the graphic area. the attribute function is defined as follows. attribute ram 1byte x x x x d3 d2 d1 d0 d3 d2 d1 d0 function 0 0 0 0 normal display 0 1 0 1 reverse display 0 0 1 1 inhibit display 1 0 0 0 blink of normal display 1 1 0 1 blink of reverse display x: invalid 1 0 1 1 blink of inhibit display display mode code function operand 10010000 display off D 1001xx10 cursor on, blink off D 1001xx11 cursor on, blink on D 100101xx text on, graphic off D 100110xx text off, graphic on D x: invalid 100111xx text on, graphic on D 1 0 0 1 d3 d2 d1 d0 cursor blink on: 1, off: 0 cursor display on: 1, off: 0 text display on: 1, off: 0 graphic display on: 1, off: 0 note: it is necessary to turn on ?text display? and ?graphic display? in the following cases. a) combination of text / graphic display b) attribute function

T6963CFG 2007-05-15 21 note: a status check for auto mode (sta2, sta3 should be checked between sending of each datum. auto reset should be performed after checking sta3 = 1 (sta2 = 1). re fer to the following flowchart. a) auto read mode b) auto write mode

T6963CFG 2007-05-15 23 screen peek code hex. function operand 11100000 e0h screen peek D this command is used to transfer 1 byte of displayed data to the data stack; this by te can then be read from the mpu by data access. the logical combination of text and graphic display data on the lcd screen can be read by this command. the status (sta6) should be checked just after the screen peek command. if the address determined by the set address pointer command is not in the graphic area, this command is ignored and a status flag (sta6) is set. refer to the following flowchart. note: this command is available when hardware column number and software column number are the same. hardware column number is related to md2 and md3 setting. software column number is related to se t text area and set graphic area command.
T6963CFG 2007-05-15 24 screen copy code hex. function operand 11101000 e8h screen copy D this command copies a single raster line of data to the graphic area. the start point must be set usin g the set address pointer command. note 1: if the attribute function is bei ng used, this command is not available. (with attribute data is graphic area data.) note 2: with dual ? scan, this command cannot be used (becaus e the T6963CFG cannot separate the upper screen data and lower screen data). refer to the following flowchart. note: this command is available when hardware column number and software column number are the same. hardware column number is related to md2 and md3 setting. software column number is related to se t text area and set graphic area command.
