Lifetime is tested at average 50% pixels on and is rated as Hours until Half‐Brightness. The Display OFF command can be used to extend the lifetime of the display. Luminance of active pixels will degrade faster than inactive pixels. Residual (burn‐in) images may occur. To avoid this, every pixel should be illuminated uniformly.

During execution of an instruction, the Busy Flag = “1”. When BF = “0” instructions can be sent to the controller. Clear Display RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 0 DB1 0 DB0 1 This instruction is used to clear the display by writing 0x20 in all DDRAM addresses. This instruction does not change the DDRAM Address. Return Home RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 0 DB1 1 DB0 0 This instruction is used to set the DDRAM Address to 0x00 and shifts the display back to the original state. The cursor (if on) will be at the first line’s left‐most character. The DDRAM contents on the display do not change. Entry Mode Set RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 1 DB1 I/D DB0 S I/D = Increment/Decrement When I/D = “1”, the DDRAM or CGRAM Address with automatically increment when a character code is written into or read from the DDRAM or CGRAM. The auto‐increment will move the cursor one character space to the right. When I/D = “0”, the DDRAM or CGRAM Address with automatically decrement when a character code is written into or read from the DDRAM or CGRAM. The auto‐decrement will move the cursor one character space to the left. S = Shift Entire Display When S = “1”, the entire display is shifted to the right (when I/D = “0”) or left (when I/D = “1”). I/D=1, S=1 I/D=0, S=1 [8] Display ON/OFF RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 1 DB2 D DB1 C DB0 B D = Display ON/OFF When D = “1”, the display is turned ON. When D = “0”, the display is turned OFF. Contents in DDRAM are not changed. C = Cursor ON/OFF When C = “1”, the cursor is displayed. The cursor is displayed as 5 dots on the 8th line of a character. When C = “0”, the cursor is OFF. B = Blinking Cursor When B = “1”, the entire character specified by the cursor blinks at a speed of 409.6ms intervals. When B = “0”, the character does not blink, the cursor remains on. Cursor/Display Shift RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 1 DB3 S/C DB2 R/L DB1 0 DB0 0 S/C 0 0 1 1 R/L 0 1 0 1 Shift Function Shifts the cursor position to the left (AC is decremented by 1). Shifts the cursor position to the right (AC is incremented by 1). Shifts the entire display to the left. The cursor follows the display shift. Shifts the entire display to the right. The cursor follows the display shift. When the display is shifted repeatedly, each line moves only horizontally. The second line display does not shift into the first line. The Address Counter does not change during a Display Shift. Function Set RS 0 R/W 0 DB7 0 DB6 0 DB5 1 DB4 DL DB3 1 DB2 0 DB1 FT1 DB0 FT0 DL = Interface Data Length When DL = “1”, the data is sent or received in 8‐bit length via DB7...DB0. When DL = “0”, the data is sent or received in 4‐bit length via DB7...DB4. When the 4‐bit data length is used, the data must be sent or received in two consecutive writes/reads to combine the data into full 8‐bits. FT1, FT0 = Font Table Selection FT1 0 0 1 1 FT0 0 1 0 1 Font Table English / Japanese Western European #1 English / Russian Western European #2 Note: Changing the font table during operation will immediately change any data currently on the display to the corresponding character on the newly selected font table. [9] Set CGRAM Address RS 0 R/W 0 DB7 0 DB6 1 DB5 ACG5 DB4 ACG4 DB3 ACG3 DB2 ACG2 DB1 ACG1 DB0 ACG0 This instruction is used to set the CGRAM address into the Address Counter. Data can then be written to or read from the CGRAM locations. See section: “How to use CGRAM”. ACG5...ACG0 is the binary CGRAM address. Set DDRAM Address RS 0 R/W 0 DB7 1 DB6 DB5 DB4 DB3 ADD6 ADD5 ADD4 ADD3 DB2 ADD2 DB1 ADD1 DB0 ADD0 This instruction is used to set the DDRAM address into the Address Counter. Data can then be written to or read from the DDRAM locations. ADD6...ADD0 is the binary DDRAM address. Line 1 = Address 0x00 through 0x13 Line 2 = Address 0x40 through 0x53 Line 3 = Address 0x14 through 0x27 Line 4 = Address 0x54 through 0x67 1 00 40 14 54 2 01 41 15 55 3 02 42 16 56 4 03 43 17 57 5 04 44 18 58 6 05 45 19 59 7 8 06 07 46 47 1A 1B 5A 5B 9 08 48 1C 5C 10 09 49 1D 5D 11 0A 4A 1E 5E 12 0B 4B 1F 5F 13 0C 4C 20 60 14 0D 4D 21 61 15 0E 4E 22 62 16 0F 4F 23 63 17 10 50 24 64 18 11 51 25 65 19 12 52 26 66 20 13 53 27 67 Read Busy Flag and Address Counter RS 0 R/W 1 DB7 BF DB6 AC6 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0 This instruction is used to read the Busy Flag (BF) to indicate if the display controller is performing an internal operation. The Address Counter is read simultaneously with checking the Busy Flag. When BF = “1”, the controller is busy and the next instruction will be ignored. When BF = “0”, the controller is not busy and is ready to accept instructions. AC6...AC0 is the binary location of either the CGRAM or DDRAM current address. Write Data to CGRAM or DDRAM RS 1 R/W 0 DB7 DB6 DB5 DB4 DB3 Write Data DB2 DB1 DB0 This instruction is used to write 8‐bits of data to the CGRAM or DDRAM at the current address counter. After the write is complete, the address is automatically incremented or decremented by 1 according to the Entry Mode. Read Data from CGRAM or DDRAM RS 1 R/W 1 DB7 DB6 DB5 DB4 DB3 Read Data DB2 DB1 DB0 This instruction is used to read 8‐bits of data to the CGRAM or DDRAM at the current address counter. After the read is complete, the address is automatically incremented or decremented by 1 according to the Entry Mode. The Set CGRAM Address or Set DDRAM Address Instruction must be executed before this instruction can be performed, otherwise the first Read Data will not be valid. [10] MPU Interface When DL is set for 8‐bit mode, the display interfaces with the MPU with DB7...DB0 (DB7 is the MSB). When DL is set for 4‐bit mode, the display interfaces with the MPU with only DB7...DB4 (DB7 is the MSB). Each instruction must be sent in two operations, the 4 high‐order bits first, followed by the 4 low‐order bits. The Busy Flag must be checked after completion of the entire 8‐bit instruction. 6800‐MPU Parallel Interface (default) Item Address setup time Address hold time System cycle time Pulse width (write) Pulse width (read) Data setup time Data hold time Read access time Output disable time Signal RS RS E E DB7...DB0 DB7...DB0 DB7...DB0 DB7...DB0 Symbol tAS68 tAH68 tCY68 tPW68(W) tPW68(R) tDS68 tDH68 tACC68 tOD68 Min. 20 0 500 250 250 40 20 ‐ 10 [11] Typ. ‐ ‐ ‐ ‐ ‐ ‐ ‐ ‐ ‐ Max. ‐ ‐ ‐ ‐ ‐ ‐ ‐ 180 ‐ Unit ns ns ns ns ns ns ns ns ns Note CL=100pF 8080‐MPU Parallel Interface Item Address setup time Address hold time System cycle time Pulse width (write) Pulse width (read) Data setup time Data hold time Read access time Output disable time Signal RS RS /WR /RD DB7...DB0 DB7...DB0 DB7...DB0 DB7...DB0 Symbol tAS80 tAH80 tCY80 tPW80(W) tPW80(R) tDS80 tDH80 tACC80 tOD80 Min. 20 0 500 250 250 40 20 ‐ 10 [12] Typ. ‐ ‐ ‐ ‐ ‐ ‐ ‐ ‐ ‐ Max. ‐ ‐ ‐ ‐ ‐ ‐ ‐ 180 ‐ Unit ns ns ns ns ns ns ns ns ns Note CL=100pF Serial Interface In serial interface mode, instructions and data are both sent on the SDI line and clocked in with the SCL line. /CS must go LOW before transmission, and must go HIGH when switching between writing instructions and writing data.

CGRAM is stored in positions 0x00 through 0x07 of the font table. Therefore, to write the first CGRAM character to the display, you would move the cursor to the desired DDRAM location on the display and write character data 0x00.
