[General] Need to Select a suitable microcontroller

[Revathysrini]

Hi friends,

I need to interface 10 sensors(analog), 2 stepper motors and 4 solenoid with a microcontroller.

For the above requirement, which microcontroller is more suitable..and what are the factor i need to consider for selecting a microcontroller.


Thanks,
Revathy

The micro should have 10 ADC channels and Vref+ and Vref- pins, 12 digital IO pins (8 for stepper motors and 4 for solenoids) If your code size is within 4 KB or 8 KB then choose a micro with 10 ADC channels, I2C port and 4 to 8 KB ROM and 1 KB RAM . You can use MCP23017 port expander. You will get 16 IO pins. You will also need ULN2003A for stepper motor. Is stepper Bi-polar or Uni-polar?
