Semigraphic microprocessor by SGS-Thomson Microelectronics
EF9345 pinout 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 [ edit ] 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 8 colors (3-bit RGB palette): On-Chip Character Generator [ edit ] The on-chip character generator offered several character sets, including alphanumeric and videotext compatible semigraphics.[1]
