Standard TV microcontrollers with
On-Screen Display (OSD)
Preliminary specification
SAA55xx
1 FEATURES
• Single-chip microcontroller with integrated On-Screen
Display (OSD)
• Versions available with integrated data capture
• One Time Programmable (OTP) memory for both
program Read Only Memory (ROM) and character sets
• Single power supply: 3.0 to 3.6 V
• 5 V tolerant digital inputs and I/O
• 29 I/O lines via individual addressable controls
• Programmable I/O for push-pull, open-drain and
quasi-bidirectional
• Two port lines with 8 mA sink (at <0.4 V) capability, for
direct drive of Light Emitting Diode (LED)
• Single crystal oscillator for microcontroller, OSD and
data capture
• Power reduction modes: Idle and Power-down
• Byte level I2C-bus with dual port I/O
• Pin compatibility throughout family
• Operating temperature: −20 to +70 °C.
2 GENERAL DESCRIPTION
The SAA55xx standard 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 some
versions include an integrated data capture and display
function.
The data capture hardware has the capability of decoding
and displaying both 525 and 625-line World System
Teletext (WST), Video Programming System (VPS) and
Wide Screen Signalling (WSS) information. The same
display hardware is used both for Teletext and OSD, which
means that the display features available give greater
flexibility to differentiate the TV set.
The SAA55xx standard family offers a range of
functionality from non-text, 16-kbyte program ROM and
256-byte Random Access Memory (RAM), to a 10-page
text version, 64-kbyte program ROM and 1.2-kbyte RAM.
