M35046-XXXSP/FP

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS

DESCRIPTION

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.

Function

Connect loop filter to this pin.

Connect to GND.
When “L”, this pin resets the internal IC circuit. Hysteresis input. Built-in pull-up resistor.
This is the chip select input pin, and when serial data transmission is being carried out, it

goes to “L”. Hysteresis input. Built-in pull-up resistor.

__

When CS pin is “L”, SIN serial data is taken in when SCK rises. Hysteresis input. Built-in
pull-up resistor.

This is the pin for serial input of data and addresses for the display control register and
the display data memory. Hysteresis input. Built-in pull-up resistor.

This is the pin for external clock input.
Please connect to +5V with the power pin.

This is the output port. Port data is set by PTD6.

MEMORY CONSTITUTION

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.

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).

(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.

RSEL1 RSEL0 DIVS1 DIVS0 Display frequency area

0 0 0 0 63.0 to 70.0

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 (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)

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.

SERIAL DATA INPUT TIMING

(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 in­put 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.

12 dots

18 dots

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 : Hatching represents
border.

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.

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.
