● For Medium-scale LCD
● Wide Operating Voltage 2.7 to 5.0V
● On Chip Character Generator ROM
■ DESCRIPTION
The SED1335F is a graphics and character display controller for use with medium scale dot matrix LCDs.
The SED1335F generates all the signals required by the display memory and LCD drivers, and incorporates a
character generator ROM, so that flexible, low power, display systems can be designed with a minimum number
of external components.
The SED1335F's high speed MPU interface can be configured for both 6800 family and 8080 family processors,
and the rich command set allows the user to create a layered display of characters and graphics, scroll the
display, and assign display attributes to selected areas of the screen with a minimum of MPU intervention.
The controller also functions as a pipline buffer between the MPU and display memory so that low cost, medium
speed SRAM can be used.
The SED1335F character generator system supports user defined characters, which can be used alone, or in
conjunction with the on board character set.
■ FEATURES
● Supports 64K bytes of memory
....4K bytes of user definable characters
....60K bytes of display memory
● 160 JIS 5×7 pixel characters internal
● Supports external character ROM or RAM
....8×8 or 8×16 pixel characters
....Allows mixing of ROM RAM character sets
● Variable LCD duty cycle, from 1/2 to 1/256
● Low power CMOS fabrication
....5mA (typical)
....0.05µA (typical), standby
● Supply voltage 2.7 to 5.5V
● Package .. SED1335FOA: QFP5-60pin (plastic)
SED1335FOB: QFP6-60pin (plastic)
● 6800 and 8080 family compatibility, 2-pin programmable
● Software compatible with SED1330 and SED1336
● Programmable cursor movement
● Flexible scrolling
....Scrolling in both horizontal and vertical directions
....Scrolling of selected areas of the display
● Multimode display
....Up to 2 layers of mixed character and graphics
....Up to 3 layers of graphics
● Selectable display synthesis
....Display attributes (reverse video, flashing,
etc.)for selected areas of the display
....Simple animation
