描述 Description

GENERAL DESCRIPTION
The MTV012A micro controller is an 8051 CPU core-embedded device specially tailored to CRT monitor applications. It includes an 8051 CPU core, 256-byte SRAM, 14 built-in PWM DACs, DDC1/DDC2B interface, 24Cxx series EEPROM interface and an 8K-byte internal program ROM.FEATURES
   8051 core.
   256 bytes internal RAM.
   8K bytes program Mask ROM.
   14 channels 10V open drain PWM DAC, 10 dedicated channels
      and 4 channels shared with I/O pin.
   20 bi-direction I/O pin, 12 dedicated pin, 4 shared with DAC,
      4 shared with DDC/IIC interface.
   3 output pins shared with H/V sync output and self test output pins.
   SYNC processor for composite sync separation, polarity
      and frequency check, and polarity adjustment.
   Built-in monitor self test pattern generator.
   Built-in Low Power Reset circuit.
   IIC interface for DDC1/DDC2B and EEPROM, only one EEPROM needed to store
      DDC1/DDC2B and display mode information.
   Watch dog timer with programmable interval.
   40 pin PDIP package.
