B. MTV312M64
The MTV312M micro-controller is an 8051 CPU core embedded device especially tailored for CRT/LCD
Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in PWM DACs, VESA DDC interface, 4-channel A/D
converter, and a 64K-byte internal program Flash -ROM.
A "CMOS output pin" means it can sink and drive at least 4mA current. It is not recommended to use such
pin as input function.
A "open drain pin" means it can sink at least 4mA current but only drive 10~20uA to VDD. It can be used as input or output function and needs
