GENERAL DESCRIPTION
The SAA5355 FTFROM (Five-Two-Five-ROM) is a single-chip VLSI NMOS crt controller capable of handling the display
functions required for a 525-line, level-3 videotex decoder. Only minimal hardware is required to produce a videotex
terminal using FTFROM the simplest configuration needs just a microcontroller and 4 Kbytes of display memory.
Features
• Minimal additional hardware required
• Screen formats of 40/80 character by 1-to-25 row display
• 512 alphanumeric or graphical characters on-chip or extendable off-chip
• Serial attribute storage (STACK) and parallel attribute storage
• Dynamically redefinable character (DRCS) capability over full field
• Interfaces with 8/16-bit microprocessors with optional direct memory access
• On-chip scroll map minimizes data to be transferred when scrolling
• 32 on-screen colours redefinable from a palette of 4096
• Three on-chip digital-to-analogue converters which compensate for crt non-linearity
• Memory interface capable of supporting multi-page terminals. FTFROM can access up to 128 Kbytes of display
memory
• Programmable cursor
• Programmable local status row
• Three synchronization modes:
stand-alone
built-in oscillator operating with an external 6,041957 MHz crystal
simple slave
directly synchronized from the source of text composite sync
phase-locked slave indirect synchronization allows picture-in-text displays (e.g. VCR/VLP video with text overlay)
• On-chip timing with composite sync output
• Zoom feature which allows the height of any group of rows to be increased to enhance legibility
