Enhanced TV microcontrollers with
On-Screen Display (OSD)
Objective specification
SAA567x; SAA569x
1 FEATURES
• Single-chip higher frequency microcontroller with
integrated On-Screen Display (OSD)
• Support for 50/60 Hz, 100/120 Hz and Progressive
Scan display modes.
• Versions available with integrated Data Capture
• Both active HIGH and active LOW reset pins
• OTP memory for both Program ROM and character sets
• Easy connection of external ROM

• Pin compatibility throughout family
• Operating temperature: −20 to +70 °C.
2 GENERAL DESCRIPTION
The SAA567x; SAA569x family of microcontrollers are a
derivative of the Philips industry-standard 80C51
microcontroller and are intended for use as the central
control mechanism in a television receiver. They provide
control functions for the television system, OSD and
incorporate an integrated Data Capture and display
function for either Teletext or Closed Caption.
The devices offer all the features from the SAA56xx family
with the addition of support for a range of Progressive
Scan display modes.
The Data Capture hardware can decode and display both
525-line and 625-line World System Teletext (WST),
Closed Caption information, Video Programming System
(VPS) information and Wide Screen Signalling (WSS)
information. The same display hardware is used for
Teletext, Closed Caption and On-Screen Display, which
means that the display features available give greater
flexibility to differentiate the TV set. The VBI data services
supported by each device is specified in Chapter 4
The family of devices offers a range of memory variants
with Program ROM sizes of 128 and 192 kbytes, also up
to 14 kbytes of RAM.
Another new feature in the SAA567x; SAA569x family of
products supports the addition of external ROM to provide
up to a total of 256 kbytes of program ROM (e.g.
192 kbytes internal + 64 kbytes external to the SAA567x;
SAA569x) with no external logic.
