The SAA5288 is a microcontroller for use in televisions
with an OSD generator compatible with the Economy
Teletext/TV microcontroller family (SAA5290, SAA5291,
SAA5296 etc.). TV control facilities are provided by an
on-chip industry standard 80C51 microcontroller and a
1 kbyte DRAM is included for OSD memory.
Hardware and software compatibility with the Economy
Teletext/TV microcontroller family minimizes the changes
required to develop a TV control function for areas where
teletext is not broadcast.
The device cannot acquire Teletext but is based on a
Teletext device. Therefore, throughout this document
references are made to Teletext especially when
describing the Display/OSD section. The Display/OSD
section is fully compatible with a Teletext display and has
all the features associated with Teletext (i.e. double
height/width, flash, teletext boxes, graphics, etc.).
The Display section is described with reference to Teletext
to allow software compatibility with the Economy
Teletext/TV microcontroller family.
260 characters in mask programmed ROM
