Short description: Semigraphic microprocessor by SGS-Thomson Microelectronics
The EF9345 from SGS-Thomson Microelectronics, Inc., was a semigraphic[1] microprocessor for video image control,[1] encapsulated in a 40-pin DIP and used primarily in the Matra Alice 32,[2] Matra Alice 90[3] and Philips VG5000 microcomputers.[4]
The EF9345 was capable of displaying 8 colors (RGB primaries), 128 alphanumeric characters and 128 semigraphic characters.[5] It had one semigraphic mode and 40- and 80-column text modes.[5] It was able to address up to 16KB of dedicated video RAM.
Video Modes
- 50/60Hz output
- Semigraphics:
- 40 characters x 25 rows text mode (similar to teletext):[5]
- 8 x 10 pixel font[5]
- Selectable background and foreground colors
- Styles: double height, double width, blinking, reverse, underline, conceal, insert, accentuation of lowercase characters
- 80 characters x 25 rows text mode:
- 6 x 10 pixel font[5]
- Styles: blinking, underlining, reverse, color
