In the part selector in LPC4300 Series: High-Performance Microcontrollers (MCUs) based on Arm® Cortex®-M4/M0 Cores|NXP , I find in the 'ADC(bits)' column, LPC4370FET100 shows 12, and LPC4370FET256 shows 10. But I can't find any other special description of this in the their datasheet. Is it just a 'typo', or this ADC bits of FET256 is really can only achieve 10bits?

Hi Hua,

     No, the web selection is not correct, LPC4370FET256 can support both 10 bit ADC(ADC0,1) and 12bit ADC, but LPC4370FET100 just can support 12-bit ADC, it doesn't have the 10 bit ADC.

   You can find this information in the LPC43xx user manual:
