SED1353 GRAPHICS LCD CONTROLLER
s DESCRIPTION
The SED1353 is a dot matrix graphic LCD controller supporting resolutions up to 1024x1024. It is capable of displaying a maximum of 256 simultaneous colors out of a possible 4096 or 16 gray shades. Design flexibility allows the SED1353 to interface to either an MC68000 family microprocessor or an 8/16-bit MPU/bus with minimum external logic. The Static RAM (SRAM) interface used for the display buffer is optimized for speed and performance, supporting up to 128K bytes. Two power save modes, combined with operating voltages of 2.7 volts through 5.5 volts, allow for a wide range of applications while providing minimum power consumption.
s FEATURES * pin compatible with the SED1352 * 16-bit 16 MHz MC68xxx MPU interface * 8/16-bit MPU interface controlled by a READY
(or WAIT#) signal * option to use built-in index register or direct-mapping to access one of sixteen internal registers * 2-terminal crystal or external oscillator support * 8/16-bit SRAM interface configurations * split screen display support allowing two different images to be simultaneously displayed * virtual display support (displays images larger than the panel size through the use of panning) * display modes: black-and-white display 2/4 bits per pixel, 4/16-level gray-scale display 2/4/8 bits per pixel, 4/16/256-level color display * two software power-save modes

s FUNCTIONAL BLOCK DESCRIPTION
Bus Signal Translation According to configuration setting VD2, Bus Signal Translation translates either MC68000 type MPU signals or Ready type MPU signals to internal bus interface signals. Control Registers The Control Register contains 16 internal control and configuration registers. These registers can be accessed by either direct-mapping or using the built-in internal index register. Sequence Controller The Sequence Controller generates horizontal and vertical display timings according to the configuration registers settings. LCD Panel Interface The LCD Panel Interface performs frame rate modulation and output data pattern formatting for both passive monochrome and passive color LCD panels. Look-Up Table The Look-Up Table contains three 16x4-bit wide palettes. In gray shade modes, the "green" palette can be configured for the re-mapping of 16 possible shades of gray. In color modes, all three palettes can be configured for the re-mapping of 4096 possible colors. Port Decoder According to configuration settings VD1, VD12 VD4, IOCS# and address lines AB9-1, the Port Decoder validates a given I/O cycle. Memory Decoder According to configuration settings VD15 VD13, MEMCS# and address lines AB19-17, the Memory Decoder validates a given memory cycle. Data Bus Conversion According to configuration setting VD0, Data Bus Conversion maps the external data bus, either 8-bit or 16-bit, into the internal odd and even data bus. Address Generator The Address Generator generates display refresh addresses to be used to access display memory. MPU / CRT Selector The MPU / CRT Selector grants access to the display memory from either the MPU or the display refresh circuitry. Display Data Formatter The Display Data Formatter reads in the display data from the display memory and outputs the correct format for all supported gray shade and color selections. Clock Inputs / Timing Clock Inputs / Timing generates the internal master clock according to gray-level / color selected and display memory interface.The master clock (MCLK) can be: - MCLK = input clock - MCLK = 1/2 input clock - MCLK = 1/4 input clock. Pixel clock = input clock = fOSC. SRAM Interface The SRAM Interface generates the necessary signals to interface to the Display Memory (SRAM).

In other bus interfaces, this is the active low input to write data into an internal register. In MC68000 MPU interface, this pin is connected to the AS# pin of MC68000. This input pin will indicate a valid address is available on the address bus. In other bus interfaces, this is the active low input to read data from an internal register. Active low input to indicate the attempt to access the display memory. Active low input to write data to the display memory. This pin should be tied to VDD in an MC68000 MPU interface. Active low input to read data from the display memory. This pin should be tied to VDD in an MC68000 MPU interface. For MC68000 MPU interface, this pin is connected to the DTACK# pin of MC68000 and will be driven low when ever a data transfer is complete. In other bus interfaces, this output is driven low to force the system to insert wait states when needed. READY is placed in a high-impedance (Hi-Z) state after the transfer is completed.

For 16-bit interface, VD0-VD7 are connected to the display memory data bus of even byte addresses and VD8-VD15 are connected to the display memory data bus of odd byte addresses. The output drivers of these pins are tri-stated when RESET is high. On the falling edge of RESET the values of VD0-VD15 are latched into the chip to configure various hardware options.

The data format depends on the specific panel connected. For 4-bit single panels, these bits are driven 0 (low state). Display data shift clock. Data is shifted into the LCD X-drivers on the falling edge of this signal. Display data latch clock. The falling edge of this signal is used to latch a row of display data in the LCD X-drivers and to turn on the row driver (Y driver). For format 1 of 8-bit single color panels this is the second shift clock. For all other modes,this is the LCD backplane BIAS signal. This output toggles once every n LP periods, as programmed in AUX[05] Vertical scanning start pulse. A logic `1' on this signal, sampled by the LCD module on the falling edge of LP, is used by the panel row driver (Y driver) to indicate the start of the vertical frame. LCD enable signal output. It can be used externally to turn off the panel supply voltage and backlight.

s SUMMARY OF CONFIGURATION OPTIONS
Pin Name VD0 VD1 VD2 VD3 value on this pin at falling edge of RESET is used to configure: 1 16-bit host bus interface Use direct-mapping for I/O accesses MC68000 MPU interface Swap of high and low data bytes in 16-bit bus interface Select I/O mapping address bits [9:1]. VD12-VD4 These nine bits are latched on power-up and are compared to the MPU address bits [9-1]. A valid I/O cycle combined with a valid address will enable the internal I/O decoder. Therefore, both types of I/O mapping are limited to even address boundaries to determine either the absolute or indexed I/O address of the first register. Note that a "valid I/O cycle" includes IOCS# being toggled low. Select memory mapping address bits [3:1] These three bits are latched on power-up and are compared to the MPU address bits [19-17]. A valid memory cycle combined with a valid address will enable the internal memory decoder. As only the three most significant VD15-VD13 bits of the address are compared, the maximum amount of memory supported is 128K bytes. Note that a "valid memory cycle" includes MEMCS# being toggled low. When using 128K byte memory it must be mapped at an even address such that all 128K bytes is available without a change in state on A17, as this would invalidate the internal compare logic. 0 8-bit host bus interface Use indexed mapping for I/O accesses MPU / Bus interface with memory accesses controlled by a READY (WAIT#) signal No byte swap of high and low data bytes in 16-bit bus interface (1/0)
