3 / 80 page  1999 Jun 11 3 Philips Semiconductors Product specification Microcontrollers for NTSC TVs with On-Screen Display (OSD) and Closed Caption (CC) P8xCx70 family 1 FEATURES • Fully static 80C51 CPU • 64-kbyte programmable ROM • 1-kbyte RAM • On-chip 12 MHz crystal oscillator • Eight 7-bit PWM outputs for analog controls • Three input 4-bit software Analog-to-Digital Converters (ADC) • Power-on reset and Watchdog Timer • 29 I/O lines via individual addressable controls • Eight port lines (Port 2) with 10 mA LED sink (<1 V) capability • On-Screen Display (OSD) and Closed Caption (CC) with V-chip function • Byte-level I2C-bus interface up to 400 kHz • Three power reduction modes: Standby, Idle and Power-down • Power supply: 5.0 V ±10% • Operating temperature: −20 to +70 °C • 52-pin shrink dual in-line package (SDIP52). 2 GENERAL DESCRIPTION The P8xCx70 family consists of the following devices: • P83C270 • P83C370 • P83C570 • P83C770 • P87C770. The term P8xCx70 is used throughout this data sheet to refer to all family members; differences between devices are highlighted in the text. The P8xCx70 family of microcontrollers are 8-bit, 80C51-based microcontrollers specifically designed for the NTSC TV market. Each device has an On-Screen Display, control functions and Closed Caption that extracts, decodes (software) and displays caption signals from NTSC TV signals. Extended Data Service (XDS) is via the software command interpreter and the V-chip is also implemented. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE ROM RAM NAME DESCRIPTION VERSION P83C270AAR SDIP52 plastic shrink dual in-line package; 52 leads (600 mil) SOT247-1 24-kbyte 512-byte P83C370AAR 32-kbyte 512-byte P83C570AAR 48-kbyte 1-kbyte P83C770AAR 64-kbyte 1-kbyte P87C770AAR 64-kbyte (OTP) 1-kbyte |
