The EF9345 from SGS-Thomson Microelectronics, Inc., was a semigraphic[1] single chip 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] It was also the video processor of the Minitel 1b terminals, built by either Alcatel and Philips at more than 2 million of units.

The EF9345 was capable of displaying 8 colors (RGB primaries), 128 alphanumeric characters and 128 semigraphic characters.

The on-chip character generator offered several character sets, including alphanumeric and videotext compatible semigraphics.
