12 bit ADC low cost microcontroller

[Amod]

Iam searching for a low cost 12 bit ADC microcontroller (20 or 28 pin) with eeprom. Kindly suggest.

Take a look at the chart on the Microchip site and tick the 12-bit for the ADC resolution bits, and then the EEPROM amount, then the 20-pin or 28-pin for the pin count:

You will then see the price of the device. Even though the price given is for 5000 devices bought, you can still see the least expensive of them.

Don't forget to also check if the device has enough RAM and flash memory for your project.

I looked at the table, but I wonder how it's classify the flash size. It seems that kilobytes is half of the real available code size, which it will works with words.

Microchip have always done that type of thing with the flash memory size.

On an 18F device or a 16-bit device, a single byte can be read from flash memory, but 14-bit devices can only read a minimum of 14-bits, which Microchip classes as a "word"

So if looking at an 18F device or a 16-bit device, the Kbyte size value is the one to look at because not all flash memory holds program code, it can also hold lots of tables of data and String data.
