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 an external pull up resistor. A “8051 standard pin” is a pseudo open drain pin. It can sink at least 4mA current when output is at low level, and drives at least 4mA current for 160nS when output transits from low to high, then keeps driving at 100uA to maintain the pin at high level. It can be used as input or output function. It needs an external pull up resistor when driving heavy load device. 4mA 10uA 120uA 2 OSC period delay 4mA Output Data Input Data 8051 Standard Pin Pin 4mA No Current Output Data 4mA Pin Input Data 4mA Output Data Pin CMOS Output Pin Open Drain Pin POWER CONFIGURATION The MTV312M can work on 5V or 3.3V power supply system. In 5V power system, the VDD pin is connected to 5V power and the VDD3 needs an external capacitor, all output pins can swing from 0~5V, input pins can accept 0~5V input range. However OSC1, OSC2 and ADC input (if selected) pins must be kept below 3.3V. In 3.3V power system, the VDD and VDD3 are connected to 3.3V power, all output pins swing from 0~3.3V, HSYNC, VSYNC and open drain pin can accept 0~5V input range, other pins must be kept below 3.3V. 5V VDD VDD3 10u 3.3V VDD VDD3 MTV312M in 5V System MTV312M in 3.3V System Revision 0.95 -3- 2001/07/03 MYSON TECHNOLOGY PIN DESCRIPTION Name VDD3 VDD VSS X2 X1 RST DA0/P5.0 DA1/P5.1 DA2/P5.2 DA3/P5.3 DA4/P5.4 DA5/P5.5 DA6/P5.6 DA7/HCLAMP DA.
