■ OVERVIEW OF THE FUNCTIONAL BLOCKS
BUS Signal Translation
This block converts the SED1353 internal bus so that it may be used for MC68000 series MPU or READY
terminal controlled MPU series. This conversion is done through the setting of VD2 terminal from the Configuration Option (see page 11).
Control Register
This register block consists of 16 types of control registers. Access to these registers are available either
through the direct mapping approach or index register approach.
Sequence Controller
This block generates horizontal and vertical display timing being set up in the internal register.
LCD Panel Interface
This block selects a gray scale for passive monochrome and color LCD panels through timing, then outputs
data to the LCD panel.
Lookup Table
This block consists of each RGB 16 × 4-bit palettes. In the monochrome gray scale mode, a gray scale pattern
can be specified using the “Green” palette. In the color mode, all RGB palettes are used to set up a color
pattern out of 4096 colors.
Port Decoder
This decoder validates a given I/O cycle through setup of VD1 terminal, VD2 to VD4 terminals, IOCS # terminal
and address lines AB9 to 1 from the Configuration Option (see page 11).
Memory Decoder
This decoder validates a given memory cycle through setup of VD15 to VD13, MEMCS # terminal and address
lines AB19 to 17 from the Configuration Option (see page 11).
Data Bus Conversion
This block connects an external data bus (8 or 16 bits) to the internal data bus through the setup of VDD terminal
from the Configuration Option (see page 11).
Address Generator
This block generates the address used to validate access to the display memory.
MPU/CRT Selector
This block arbitrates between MPU accees to the display memory and an access to it for LCD display.
Display Data Fomatter
This block reads data from the display memory, then outputs it in the format consistant with the specified
display mode (monochrome/color, levels of gray scale and number of colors).
Clock Inputs/Timing
This block generates a master clock (mclk) conforming to the specified gray scale leves 1, number of colors and
display memory interface. The following master clocks are available depeding on conditions specified:
– mclk = input clock:
16-grays/16-color mode (8-bit display memory) or 256-color mode (16-bit display
memory).
– mclk = 1/2 input clock: B&W, 4-grays/4-color mode (8-bit display memory), or 16-grays scale/16-color
mode (16-bit display memory).
– mclk = 1/4 input clck: B&W, 4-grays scale/4-color mode (16-bit display memory).
Pixel clock = input clock = fOSC
SRAM Interface
This block generates the interface signal to the display memory (SRAM).

Description
Connects to the system data bus. In 8-bit bus mode, DB8 to
DB15 connect to VD0.
When MC68000 MPU interface is used, it connects to UDS#pin
(Upper Data Strobe). When other bus interface is used, it
connect to the system address bus.
Connects to the system bus.
When MC68000 MPU interface is used, it connects to LDS# pin
(Lower Data Strobe). When other bus interface is used, this pin
functions as the bus high enable input on the 16-bit system. On
8-bit bus system, it connects to VDD.
Select one of 15 internal registers.
When MC68000 MPU interface is used, it connects to R/W# pin.
This input pin selects either read cycle (active high) or write
cycle (active low) for data transmission. When other bus
interface is used, it is active low to write data to the internal
register.
When MC68000 MPU interface is used, it connects to AS# pin.
On the address bus, this input pin indicates an valid address is
available. When other bus interface is used, this pin is active low
and reads data from the internal register.
Accepts active low inputs, it displays access attempts to the
display memory.
Accepting active low inputs, it writes dat a to the display memory.
When MC68000 MPU interface is used, it connects to VDD.
Accepting active low inputs, it reads data from the display
memory. When MC68000 MPU interface is used , it connects to
VDD.
When MC68000 MPU interface is used, it is connected with
DATCK# pin. As data transfer completes, it is turned low. When
other system bus interface is used, it outputs low if the system
wait status is needed.
As data transfer completes, READY state is reset to return to
High-Z.
Accepting active high, it turns all signals non-active.

Description
They connect to the display memory data bus. When 16-bit
interface is used, VD0 to VD7 are connected to the display
memory buses in even byte address, and VD8 to VD15 are
connected to those in odd memory address. When RESET is
turned to high, output drivers of these pins are set to High-Z. At
the falling edge of RESET, values of VD0 to VD15 are latched by
this IC allowing to set various hardware options.
They connect to the display memory address buses.
It outputs active low chip select signal to the second SRAM or
SRAMs at odd byte address.
It outputs active low chip select signal to the first SRAM or
SRAMs at even byte address.
It outputs active low used when writing data to the display
memory. It is connected to the SRAM WE# pin.
It outputs active low used for reading data from the display
memory. It is connected to the SRAM OE# pin.

Description
Display data in the dual panel mode. When 4-bit single panel
is employed, LD3 to LD0 are driven to low.
Shift clock of display data. Aft the falling edge of this signal,
data is shifted to X driver on the LCD.
Latch clock of display data. At the falling edge of this signal,
line data on the LCD X driver is latched and used for turning
on the LCD Y driver.
The second shift clock for 8-bit single color panel (format)
mode. In other modes, it becomes LCD back plane bias
signal. This output is toggled one time at each frame. (Setup
of WF signal output may be changed from the internal
register.)
Vertical scan start signal.
LCD enable signal. Using this signal, you can externally turn
off the panel power and back light.
*: Conforming to the VESA flat panel interface standard.

■ OPTIONAL HARDWARE CONFIGURATION
During the RESET, SED1353 latches state of SRAM data bus (1 or 0) to offer an optimum hardware configuration to the user system. Since SED1353 has a pull down resistor inside the IC, if the following “1” applies, a
10kΩ external pull up resistor must be provided . In case of “0”, the external pull up resistor is not required.
