1.5.
C8051F91x-C8051F90x devices have a 300 ksps, 10-bit or 75 ksps 12-bit successive-approximation-
register (SAR) ADC with integrated track-and-hold and programmable window detector. ADC0 also has an
autonomous low power Burst Mode which can automatically enable ADC0, capture and accumulate
samples, then place ADC0 in a low power shutdown mode without CPU intervention. It also has a 16-bit
accumulator that can automatically average the ADC results, providing an effective 11, 12, or 13 bit ADC
result without any additional CPU intervention.
The ADC can sample the voltage at any of the GPIO pins (with the exception of P2.7) and has an on-chip
attenuator that allows it to measure voltages up to twice the voltage reference. Additional ADC inputs
include an on-chip temperature sensor, the VDD/DC+ supply voltage, the VBAT supply voltage, and the
internal digital supply voltage.
