M37161M8 Datasheet | Renesas

DESCRIPTION The M37161M8/MA/MF-XXXSP/FP and M37161EFSP/FP are singlechip microputers designed with CMOS silicon gate technology. They have an OSD and I2C-BUS interface, making them perfect for a channel selection system for TV. The M37161EFSP/FP has a built-in PROM that can be written electrically. q OSD function Display characters 32 characters ✕ 2 lines (It is possible to display 3 lines or more by software) Kinds of characters 254 kinds + 62 kinds (coloring unit) (per charactor unit) (per dot unit) Character display area OSD1 mode: 16 ✕ 26 dots OSD2 mode: 16 ✕ 20 dots CD OSD mode: 16 ✕ 20 dots Kinds of character sizes OSD1 mode: 1 kind OSD2 mode: 8 kinds CD OSD mode: 8 kinds Kinds of character colors 8 colors (R, G, B) Coloring unit dot, character, character background, raster Display position Horizontal: 128 levels Vertical: 512 levels Attribute OSD1 mode: smooth italic, underline, flash, automatic solid space OSD2 mode: border Smooth roll-up Window function 2.
