Transformer Annunciation System

[tahoka]

Hi Everyone

I am basically designing a transformer control system monitoring the parameters:
Voltage, Current, Oil and Winding Temperature.
The output would consist of LEDs, and Alarms and I am Also Planning To add a LCD Display Segment.
Can anyone suggest to me the preferable options of the microcontrollers I can use for this project.
Essential Characteristics for the uc are:
1.in built ADC
2.LCD Driver Segment
3.Timer
4.>=2 ports
