M35054-XXXFP/M35055-XXXFP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
MITSUBISHI MICROCOMPUTERS
DESCRIPTION
The M35054-XXXFP and M35055-XXXFP are TV screen display con-
trol IC which can be used to display information such as number of
channels, the date and messages and program schedules on the TV
screen.
In particular, owing to the built-in SYNC-SEP (synchronous separa-
tion) circuit, the synchronous correction circuit, external circuits can
be decrease and character turbulence that occurs when superim-
posing can be reduced. The processor is suitable for AV systems
such as VTRs, LDs, and so on.
It is a silicon gate CMOS process and M35054-XXXFP and M35055-
XXXFP are housed in a 20-pin shrink SOP package.
For M35054-001FP/M35055-001FP that are a standard ROM ver-
sions of M35054-XXXFP/M35055-XXXFP respectively, the charac-
ter pattern is also mentioned.

PIN DESCRIPTION
Function
This is the filter output pin 1.
This is the pin for test. Connect this pin to GND during normal operation.
This is the chip select 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.
When "L", this pin resets the internal IC circuit. Hysteresis input. Built-in pull-up resistor.
Please connect to +5V with the analog circuit power pin.
This is the output pin for composite video signals. It outputs 2V
P-P
composite video
signals. In superimpose mode, character output etc. is superimposed on the external
composite video signals from CVIN.
This is the input pin which determines the "white" character color level in the composite
video signal.
This is the input pin for external composite video signals. In superimpose mode, character
output etc. is superimposed on these external composite video signals.
Please connect to GND using circuit earthing pin.
This is the pin for test. Open this pin during normal operation.
This is the pin for test. Connect this pin to GND during normal operation.
This pin outputs the port output or BLNK1 (character background) signal.
This pin outputs the port output or CO1(character) signal.
Please connect to GND using circuit earthing pin (Analog side).
This is the input pin for the sub-carrier frequency (f
SC
) for generating a synchronous
signal.
A frequency of 3.580MHz is needed for NTSC, and a frequency of 4.434MHz in needed
for PAL and 3.576MHz is needed for M-PAL.
Filter output pin 2.
This is the input pin for external composite video signals. This pin inputs the external
video signal clamped sync-chip to 1.5V, and internally carries out synchronous separa-
tion.
Please connect to +5V with the digital circuit power pin.

MEMORY CONSTITUTION
Address 00
16
to EF
16
are assigned to the display RAM, address F0
16
to F8
16
are assigned to the display control registers.
The internal circuit is reset and all display control registers (address
F0
16
to F8
16
) are set to "0" and display RAM (address 00
16
to EF
16
)
__
are RAM erased when the AC pin level is "L".
When using M35054-XXXFP, set "0" in any of DA7, DAD through
DAF of addresses 00
16
through EF
16
, and of DAE and DAF of ad-
dresses F0
16
through F8
16
.
Setting the blank code "FF
16
" as a character code is an exception.
When using M35055-XXXFP, set "0" in any of DAD through DAF of
addresses 00
16
through EF
16
, and of DAE and DAF of addresses
F0
16
through F8
16
.
TESTn (n : a number) is MITSUBISHI test memory, so be sure to
observe the setting conditions.
