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 PACKAGE TYPE NUMBER NAME P83C270AAR P83C370AAR P83C570AAR P83C770AAR P87C770AAR SDIP52 DESCRIPTION plastic shrink dual in-line package; 52 leads (600 mil) VERSION SOT247-1 24-kbyte 32-kbyte 48-kbyte 64-kbyte 64-kbyte (OTP) 512-byte 512-byte 1-kbyte 1-kbyte 1-kbyte ROM RAM 1999 Jun 11 3 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ... book, full pagewidth 1999 Jun 11 VDDA VSSD VDDP VSSA VDDC XI TWO 16-BIT TIMER/ COUNTERS (T0 AND T1) CPU ALE/PROG 8-BIT WATCHDOG TIMER (T3) ROM 64-KBYTES XO RESET PSEN VPP/EA 80C51 CORE EXCLUDING ROM/RAM PARALLEL I/O PORT FUNCTION COMBINED PARALLEL I/O PORTS 4 Philips Semiconductors Microcontrollers for NTSC TVs with On-Screen Display (OSD) and Closed Caption (CC) BLOCK DIAGRAM R FB G B VSYNC HSYNC AFT0(2) AFT2(2) AFT1(2) RAM 1-KBYTE ON-SCREEN DISPLAY (OSD) 3 × 4-BIT ADCS 8-bit internal bus 4 9 × 7-BIT DACS CC DATA SLICER I2C-BUS INTERFACE 2 8 8 5 8 REFH IREF CVBS SDA(3) SCL(3) MGR380 external interrupts P2 P0 P1 P3 PWM0 to PWM8(1) STN BLK P8xCx70 family Product specification (1) Alternative functions of Port 0 except PWM0 which is an alternative function of Port 1.
