1.7.
The C8051F310/1/2/3/6 devices include an on-chip 10-bit SAR ADC with a 25-channel differential input
multiplexer. With a maximum throughput of 200 ksps, the ADC offers true 10-bit accuracy with an INL of
±1LSB. The ADC system includes a configurable analog multiplexer that selects both positive and nega-
tive ADC inputs. Ports1-3 are available as an ADC inputs; additionally, the on-chip Temperature Sensor
output and the power supply voltage (V
ADC to save power.
Conversions can be started in six ways: a software command, an overflow of Timer 0, 1, 2, or 3, or an
external convert start signal. This flexibility allows the start of conversion to be triggered by software
events, a periodic signal (timer overflows), or external HW signals. Conversion completions are indicated
by a status bit and an interrupt (if enabled). The resulting 10-bit data word is latched into the ADC data
SFRs upon completion of a conversion.
Window compare registers for the ADC data can be configured to interrupt the controller when ADC data is
either within or outside of a specified range. The ADC can monitor a key voltage continuously in back-
ground mode, but not interrupt the controller unless the converted data is within/outside the specified
range.
