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.
