B. Megawin MPC82G516A
The MPC82G516A is compatible with the instruction set of 8051 microcontroller.
Idle mode and Power-Down Mode are the two power saving modes of MPC82G516A that reduce the power consumption. Another feature of this microcontroller to lessen the power consumption is that it can operate in a lower speed by using the 8-bit system clock
There is no need for external analog to digital converter (ADC) circuit because it has its own 10-bit ADC.
