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

- 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
- 8 colors (3-bit RGB palette):
On-Chip Character Generator
The on-chip character generator offered several character sets, including alphanumeric and videotext compatible semigraphics.[1]
