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.

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 not erased and be undefinited. For detail, see "DATA

REGISTER SUPPLEMENTARY DESCRIPTION
(1) Setting external clock input and display frequency mode Set-
ting external clock input and display frequency mode (by use of
EXCK0, EXCK1 and DIV11 to DIV0 (12016), as explained here
following.
Input from the TCK pin a constant-period continuous exter-
nal clock that synchronizes with the horizontal synchronous
signal. And input from HOR pin a constant-period continu-
ous horizontal synchronous signal.
(a) When (EXCK1, EXCK0) = (0, 0) ...... External clock mode 1
Fosc = 6.3 to 80 MHz (VDD = 4.75V to 5.25V)
Never stop inputting the clock while displaying.
An internal clock which is in sync with the external input
clock is used as the display clock.
Fosc = 6.3 to 40 MHz (VDD = 3.00V to 3.60V)
Input from the TCK pin a constant-period continuous exter-
nal clock that synchronizes with the horizontal synchronous
signal. And input from HOR pin a constant period continu-
ous horizontal synchronous signal.
Because the display frequency equals the external clock
frequency, set N1 (division value) that satisfies the below
expressions to DIV11 to DIV0 (address 12016) for make the
display frequency is equal to the external clock frequency.
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) = (0, 1) ......Internal clock mode
Fosc = 20 to 120 MHz (VDD = 4.75V to 5.25V)
Clock input from the TCK pin is unnecessary. The multiply
clock of the internally generated horizontal synchronous
signal is used as the display clock.
The display frequency is set by setting the multiply value of
the horizontal synchronous frequency (of the display fre-
quency) in DIV11 to DIV0 (address 12016). Also, set the
display frequency range. (See the next page.)
Display frequency is calculated using the below expression.
Display frequency =Horizontal synchronous frequency ✕

EXCK0 = "1", or EXCK1 = "1", EXCK0 = "1"), always set the
display frequency range in accordance with the display
frequency. This range is set from DIVS0, DIVS1, DIVS2,
RSEL0 and RSEL1 (address 12016). Frequency ranges are
given here below.

(3) Notes on setting display frequency
To change external clock (display) frequency or horizontal syn-
chronization frequency, always use the following procedures.
To set EXCK1 = "0", EXCK0 = "1"
(a) Turn the display OFF. … DSPON (address 12716) = "0"
(b) Set the display frequency. … Set from DIV11 to
DIV0, DIVS0, DIVS1, DIVS2, RSEL0 and RSEL1 (ad-
dress 12016).
(c) Wait 20 ms while the horizontal synchronization signal is
being input.
(d) Turn the display ON. … DSPON (address 12716) = "1"
To set EXCK1 = "1", EXCK0 = "1"
(a) Turn the display OFF. … DSPON (address 12716) = "0"
(b) Set the display frequency. … Set from DIV11 to DIV0,
DIVS0, DIVS1, DIVS2, RSEL0 and RSEL1 (address
12016).
(c) Wait 20 ms while the horizontal synchronization signal
and external clock are being input.
(d) Turn the display ON. … DSPON (address 12716) = "1"

DATA INPUT 2

(1) I C-Bus communication function (At only VDD = 5V)
This IC has a built-in data transmission interface which utilizes
2 unidirectional buses. In communications, this IC functions as
a slave reception device.
The IC is synchronized with the serial clock (SCL) sent from
the master device and receives the data (SDA).
Communications are controlled from the start/stop states.
Also, always in put the control byte after attaining the start
state.
The below chart shows the start/stop state and control byte
configuration.

(2) Data input (Sequence)
(a) Addresses are consists of 16 bits.
(b) Data is consists of 24 bits.
(c) Addresses and data are communicated in 8-bit units. Input
the lower 8 bits before the upper 8 bits. Make input from
the MSB side.
(d) After the start state has been attained and the control byte
(7CH) received, the next 16 bits (2 bytes) are for inputting
the address. Addresses are increased in increments for
every 24 bits (3 bytes) of data input thereafter. As a result,
it is not necessary to input the address from the second
data.
Note:During external synchronous , do not stop the external clock
input from the TCK pin while inputting data.

PRECAUTION FOR USE
Notes on noise and latch-up
DATA REQUIRED FOR MASK ROM
ORDERING
In order to avoid noise and latch-up, connect a bypass capacitor
(≈0.1µF) directly between the VDD1 pin and VSS1 pin, and the
VDD2 pin and VSS2 pin using a heavy wire.
Please send the following data for mask orders.
(1) M35074-XXXSP mask ROM order confirmation form
(2) 20P4B mark specification form
(3) ROM data : EPROMs or floppy disks
*In the case of EPROMs, thres sets of EPROMs are required
per pattern.
Note for waveform timing of the horizontal signals to the HOR pin
Set horizontal synchronous signal edge* waveform timing to under
5ns and input to HOR pin.
_
*In the case of floppy disks, 3.5-inch 2HD disk (1BM format) is
required per pattern.
Set only the side which set by B/F register waveform timing under
5ns and input to HOR pin.
_
*: Set front porch edge or back porch edge by B/F register (ad-
dress 12716) .
