7. Renesas Electronics products are classified acco rding to the following three quality grades: “Standard”, “High Quality”, and
“Specific”. The recommended applications for each Renesas Electronics product depends on the product’s quality grade, as
indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular
application. You may not use any Renesas Electronics product for any application categorized as “Specific” without the prior
written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for
which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way
liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product for an

expressly specified in a Renesas Electronics data sheets or data books, et c.
“Standard”: Computers; office equipment; communications equipment; test and measurement equipment; audio and visual
equipment; home electro nic app liances; machine tool s; p ersonal electron ic equipment; and indu strial robots .
“High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-
crime systems; safety equipment; and medical equipment not specifically designed for life support.
“Specific”: Aircraft; aerospace equ i pment; submersible repeaters; nu clear reactor control systems; medical equipment or
systems for life support (e.g. artificial life support devices or systems), surgical implantations, or healthcare
interven tion (e.g. excision, et c.), and any oth er applications or purposes that pose a direct th reat to human life.
8. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,
especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation

and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names
have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.
Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been
made to the contents of the document, and these changes do not constitute any alteration to the
contents of the document itself.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

SCREEN CONSTITUTION
The screen lines and rows are determined from each address of the
display RAM. The screen constitution is shown in Figure 2.
MEMORY CONSTITUTION
Address 00016 to 11F16 are assigned to the display RAM, address
12016 to 12816 are assigned to the display control registers. The in-
ternal circuit is reset and all display control registers (address 12016
__
to 12816) are set to “0” when the AC pin level is “L”. And then RAM is
erased.
Memory constitution is shown in Figure 1.

REGISTERS DESCRIPTION
(1) Address 12016
Set display frequency by frequency
value setting. Set N1 to be “N1=fOSC/
fH”.
fOSC(MHz) : External clock frequency
for TCK pin (=display fre-
quency)
fH(kHz) : Horizontal synchronous sig-
nal frequency for HOR pin
Set registers DIVS0, DIVS1 (address
12016), RSEL0 (address 12116) and
RSEL1 (address 12216) according to
external clock frequency.
For details, see (2) Setting display fre-
quencies under Register Supplemen-
tary Description.
Any of this settings above is reguired
only when EXCK1=1, EXCK0=1.

T: The cycle of display frequency
1000 settings are possible.
Leave one line worth of space in the ver-
tical direction.
For example, 6 Π6 indicates two sets
of 6 lines with a line of spaces between
lines 6 and 7.
A line is 18 × N horizontal scan lines.
N is determined by the character size in
the vertical direction as follows:
×1 … N = 1 ×2 … N = 2
×3 … N = 3 ×4 … N = 4

REGISTER SUPPLEMENTARY DESCRIPTION
(1) Setting external clock input mode (by use of EXCK0 (12016) and
EXCK1 (12316))
Two modes given below are available for the external clock sig-
nal input. (the settings (EXCK1, EXCK0) = (0, 1), (1, 0) are forbid-
den.)
(a) When (EXCK1, EXCK0) = (0, 0), FOSC = 20 to 30 MHz
Input from the TCK pin a constant-period continuous external
clock that synchronizes with the horizontal synchronization signal.
And input from HOR pin a constant-period continuous horizontal
synchronous signal.
Never stop inputting the clock while displaying.
Do not have to set a display frequency because the clock just as
it is entered from outside is used as the display clock.
(b) When (EXCK1, EXCK0) = (1, 1), FOSC = 20 to 80 MHz
Input from the TCK pin a constant-period continuous external
clock that synchronizes with the horizontal synchronization signal.
Never stop inputting the clock while displaying.
Be sure to set a display frequency because the internal clock
made to synchronize with the clock input from outside is used as
the display clock (see the next page).

(2) Setting display frequencies
Set a display frequency by setting a frequency value for the hori-
zontal synchronization signal by use of DIV10 to DIV0 (12016).
Set display frequency area in conformity with the frequency of the
external clock signal.
Set display frequency area by use of DIVS0, DIVS1 (12016),
RSEL0 (12116), and RSEL1 (12216). Frequency area are as fol-
lows.
RSEL1 RSEL0 DIVS1 DIVS0 Display frequency area

0 0 0 0 63.0 to 70.0
1 0 0 1 56.6 to 63.0

1 0 1 1 28.3 to 31.5
0 1 1 1 23.3 to 28.3
0 0 1 1 20.0 to 23.3
Cautions in setting a display frequency
To change the external clock frequency or the horizontal synchroni-
zation frequency, follow the steps in sequence given below.
(a) Display OFF (DSPON = 0)
(b) Set the display frequency (Use DIV10 to DIV0 (12016),
DIVS0, DIVS1 (12016), RSEL0
(12116), and RSEL1 (12216).)
(c) 20-ms waiting time with the horizontal synchronization signal and
the external clock signal being input
(d) Display ON (DSPON = 1)

(1) Serial data should be input with the LSB first.
(2) The address consists of 16 bits.
(3) The data consists of 16 bits.
(4)
__
The 16 bits in the SCK after the CS signal has fallen are the
address, and for succeeding input data, the address is
incremented every 16 bits. Therefore, it is not necessary to in-
put the address from the second data.

CHARACTER FONT
Images are composed on a 12 × 18 dot matrix, and characters can
be linked vertically and horizontally with other characters to allow the
display the continuous symbols.
Fig. 8 Example for displaying a continuous pattern after combining characters in the horizontal or vertical direction
Character code FF16 is fixed as a blank without background.
Therefore, cannot register a character font in this code.
When the character extends
to the top line of the matrix,
no border is left at the top.
When the character extends
to the bottom (18th) line of
the matrix, no border is left
at the bottom.

NOTE FOR SUPPLYING POWER
__
Timing of power supplying to AC pin
The internal circuit of M35046-XXXSP/FP is reset when the level of
__
the auto clear input pin AC is “L”. This pin in hysteresis input with the
__
pull-up resistor. The timing about power supplying of AC pin is shown
in Figure 11.
Timing of power supplying to VDD1 and VDD2.
Supply power to VDD1 and VDD2 at the same time.
DATA REQUIRED FOR MASK ROM ORDERING
Please send the following data for mask orders.
(1) M35046-XXXSP/FP mask ROM order confirmation form
(2) 20P4B mask specification form
(3) 20P2Q-A mask specification from
(4) ROM data (EPROM 3 sets)

After supplying the power (VDD and VSS) to M35046-XXXSP/FP and
the supply voltage becomes more than 0.8 × VDD, it needs to keep

__
Start inputting from microcomputer after AC pin supply voltage
becomes more than 0.8 × VDD and keeping 200ms wait time.
PRECAUTION FOR USE
Notes on noise and latch-up
In order to avoid noise and latch-up, connect a bypass capacitor
(≈0.1µF) directly between the VDD1 pin and VSS pin, and the VDD2 pin
and VSS pin using a heavy wire.
