3 / 92 page 1999 Mar 10 3 Philips Semiconductors Product specification Microcontrollers for PAL/SECAM TV with OSD and VST P8xCx66 family 1 FEATURES 1.1 P80C51 CPU core • 80C51 8-bit CPU • 64-kbyte Multiple Programming ROM (MTP ROM) • Two 16-bit timer/event counters • Crystal oscillator for system clock (up to 12 MHz) • 12 source, 12 vector interrupt structure with two priority levels • Enhanced architecture with: – Non-page orientated instructions – Direct addressing – Four 8-byte RAM register banks – Stack depth up to 128 bytes – Multiply, divide, subtract and compare instructions. 1.2 P8xCx66 family • ROM/RAM: see Table 1 • Pulse Width Modulated (PWM) outputs: – One 14-bit PWM output for Voltage Synthesized Tuning (VST) – Eight 7-bit PWM outputs for analog controls. • 3 Analog-to-Digital (ADC) inputs with 4-bit DAC and comparator • LED driver port: – All I/O port lines with 10 mA LED drive capability (VO <1.0 V) – Up to 5 LEDs can be driven at any one time. • Serial I/O: – Multi-master I2C-bus interface – Maximum I2C-bus frequency 400 kHz. • Watchdog timer • Improved EMC measures and slope controlled I/Os • OSD functions: – Programmable VSYNC and HSYNC active levels – Display RAM: 192 × 12 bits – Display character fonts: 128 (126 customer fonts plus 2 reserved codes) – 63 vertical starting positions controlled by software – 110 horizontal starting positions controlled by software – Character size: 4 different character sizes on a line-by-line basis – Character matrix: 12 × 18 with no spacing between characters – Foreground colours: 8 on a character-by-character basis – Background/shadowing modes: two primary modes - TV mode and Frame mode on a frame basis. Each primary mode has four sub-modes on a line basis: Sub-mode 1: Superimpose (no background) Sub-mode 2: North-West shadowing Sub-mode 3: Box background Sub-mode 4: Border shadowing – Background colours: 8 on a word-by-word basis, available in all four sub-modes – Display RAM starting address is programmable; fast switching between banks of display (RAM) characters is possible through software control – HSYNC driven PLL for OSD clock (4 to 12 MHz) – Character blinking ratio: 1 : 1 – Character blinking frequency: programmable using fVSYNC divisors of 32 and 64, on a character basis – Flexible display format using the Carriage Return code and the Space codes – Display RAM address post incremented each time new data is written into RAM – Vertical jitter cancelling circuit to avoid unstable VSYNC leading edge mismatch with HSYNC signal – OSD meshing. • Power-on reset • Packages: SDIL42 (PLCC68 for piggy-back only) • Operating voltage: 4.5 to 5.5 V • Operating temperature: −20 to +70 °C • System clock frequency: 4 to 12 MHz • OSD clock frequency: 4 to 12 MHz. |
