This document is a preliminary specification for SAA55xx TV microcontrollers with Closed Captioning (CC) and On-Screen Display (OSD) features.
This document is a preliminary data sheet for the Philips SAA55xx family of single-chip microcontrollers designed specifically for television receivers. These devices integrate an 80C51-compatible microprocessor with an On-Screen Display (OSD) engine, closed captioning support, and various power-saving modes.
The datasheet details the device features, including a programmable I/O port structure, software ADC, pulse width modulators for tuning, and memory organization. It provides quick reference data on supply voltages (3.0V to 3.6V) and operating temperatures (-20°C to +70°C), along with ordering information for different ROM sizes ranging from 16 to 64 kbytes.
| Supply Voltage Range | 3.0 to 3.6 V |
|---|---|
| Operating Temperature | -20 to +70°C |
| Storage Temperature | -55 to +125°C |
| I/O Port Count | 29 I/O ports |
| I?C-bus Speed (Master) | up to 200 kHz |
The device operates on a single power supply ranging from 3.0 to 3.6 V.
Yes, these microcontrollers include integrated Closed Captioning (CC) functionality.
The device can operate at ambient temperatures up to +70°C.
