C8051F50x/F51x
6. 12-Bit ADC (ADC0)
The ADC0 on the C8051F50x/F51x consists of an analog multiplexer (AMUX0) with 35/28 total input selec-
tions and a 200 ksps, 12-bit successive-approximation-register (SAR) ADC with integrated track-and-hold,
programmable window detector, programmable attenuation (1:2), and hardware accumulator. The ADC0
subsystem has a special Burst Mode which can automatically enable ADC0, capture and accumulate sam-
ples, then place ADC0 in a low power shutdown mode without CPU intervention. The AMUX0, data con-
version modes, and window detector are all configurable under software control via the Special Function
Registers shows in Figure 6.1. ADC0 inputs are single-ended and may be configured to measure P0.0-
P3.7, the Temperature Sensor output, V
is selected as described in Section “7. Temperature Sensor” on page 72. ADC0 is enabled when the
AD0EN bit in the ADC0 Control register (ADC0CN) is set to logic 1, or when performing conversions in
Burst Mode. ADC0 is in low power shutdown when AD0EN is logic 0 and no Burst Mode conversions are
taking place.
