RENESAS M35046

To all our customers
Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
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.

M35046 - XXXSP
The M35046-XXXSP/FP is a character pattern display control IC can
display on the liquid crystal display and the plasma display. It uses a
silicon gate CMOS process and it housed in a 20-pin shrink DIP package (M35046-XXXSP) or a 20-pin shrink SOP package (M35046XXXFP).
For M35046-001SP/FP that is a standard ROM version of M35046XXXSP/FP respectively, the character pattern is also mentioned.

Address 00016 to 11F16 are assigned to the display RAM, address
12016 to 12816 are assigned to the display control registers. The internal 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.
The screen lines and rows are determined from each address of the
display RAM. The screen constitution is shown in Figure 2.

Leave one line worth of space in the vertical 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
Πrepresents one line worth of spaces.
For details, see (2) Setting display frequencies under Register

To be used when EXCK0=1 and EXCK1=1.

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 signal input. (the settings (EXCK1, EXCK0) = (0, 1), (1, 0) are forbidden.)
(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).
(Example for input)

(2) Setting display frequencies
Set a display frequency by setting a frequency value for the horizontal 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 follows.

Cautions in setting a display frequency
To change the external clock frequency or the horizontal synchronization frequency, follow the steps in sequence given below.
(a) Display OFF
(DSPON = 0)
(b) Set the display frequency
(Use DIV10 to DIV0 (120 16),
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)

DISPLAY FORM 2
M35046-XXXSP/FP has the following four display forms.
(1) Character size
: Blanking same as the character size.
(2) Border size
: Blanking the background as a size from character.
(3) Matrix-outline size
: Blanking the background 12 × 18 dot.
When set register BETA14 to “1”, setting of blanking the
background 14 × 18 dot is possible.
(4) All blanking size
: When set register BCOL to “1”, all raster area is blanking.
