(4) OSD functions · Screen for display : 34 columns × 16 rows (standard character size) · Display for RAM : 640 × 9 bits (6 columns for control + 34 columns for display) × 16 rows × 9 bits · 377 kinds of user specified characters Caption/Text mode : (9 × 9 dots) × 125 kinds OSD mode : (12 × 18 dots) × 127 characters (127 characters can also be used in Caption/Text mode) · Various character attributes Character colors : 16 colors Character background colors : 16 colors Fringe / shadow colors : 16 colors Full screen colors : 16 colors Fringe / shadow Rounding Underline Italic character (slanting) · Close-character attribute data changing available · Vertical display start line setting in row units available (Row overlapping available) · Horizontal display start position available · Display mode specification by row (Display mode mixable) caption mode / text mode / OSD mode · Eight kinds of character size Horiz. × Vert. = (1 × 1), (1 × 2), (2 × 2), (2 × 4) (1.5 × 1), (1.5 × 2), (3 × 2), (3 × 4) · Shuttering and scrolling in row units available · Horizontal character pitch selectable : 9 to 16 dots · Polarity of R, G, B, I, BL output programmable · Polarity of HS, VS input programmable (5) Data slicer clock switching function Clock source is selective from LC oscillation or ceramic resonator (or X'tal) oscillation. (6) Bus cycle time / Instruction cycle time The LC864132B/24B/20B/16B/12B microcontrollers are designed to read the ROM twice within one instruction cycle. It has about 1.7 times performance capability within the same instruction-cycle compared to our 4-bit microcontrollers (LC66000 series). The bus cycle time indicates the speed to read ROM.
Bus cycle time 0.49 µs 7.5 µs Instruction cycle time 0.99 µs 15.0 µs System clock oscillation Ceramic or Crystal Internal RC Oscillation frequency 12.08 MHz 800k Hz Voltage 4.5 V to 5.5 V 4.5 V to 5.5 V
(7) Ports - Input/output port : 2 ports (16 lines) Input/output port programmable in nibble unit : 1 port (8 lines) (When the N-ch open drain output is selected, the data in a bit can be inputted) Input/output port programmable in a bit : 1 port (8 lines) - Input port : 2 ports (8 lines)
