(3) OSD functions · Screen for display : 34 columns × 16 rows (at standard character size) · Display for RAM : 640 × 9 bits (6 columns for control + 34 columns for display) × 16 rows × 9 bits · 380 kinds of user specified characters Caption/Text mode : (9 × 9 dots) × 126 kinds OSD mode : (12 × 18 dots) × 254 characters (127 characters can also be used for 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 unit available (Row overlapping available) · Horizontal display start position setting 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 unit available · Horizontal pitch of character selectable : 9 to 16 dots · Polarity of R, G, B, I, BL output programmable · Polarity of HS, VS input programmable (4) Data slicer clock switching function Clock source can be selected from LC oscillation or CF (or Crystal) oscillation. (5) Bus cycle time / Instruction cycle time The LC864332A/28A/24A/20A/16A/12A 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 800 kHz Supply voltage 4.5 V to 5.5 V 4.5 V to 5.5 V
