2.3.6 Analog modules

The following analog modules are available on this device:

Table 2-7. Analog modules

Module Description

16-bit analog-to-digital converters (ADC)

and programmable-gain amplifiers

(PGA)

16-bit successive-approximation ADC designed with integrated programmable

gain amplifiers (PGA)

Analog comparators Compares two analog input voltages across the full range of the supply voltage.

6-bit digital-to-analog converters (DAC) 64-tap resistor ladder network which provides a selectable voltage reference for

applications where voltage reference is needed.

12-bit digital-to-analog converters (DAC) Low-power general-purpose DAC, whose output can be placed on an external pin

or set as one of the inputs to the analog comparator or ADC.

Voltage reference (VREF) Supplies an accurate voltage output that is trimmable in 0.5 mV steps. The VREF

can be used in medical applications, such as glucose meters, to provide a

reference voltage to biosensors or as a reference to analog peripherals, such as

the ADC, DAC, or CMP.

2.3.7 Timer modules

The following timer modules are available on this device:

Table 2-8. Timer modules

Module Description

Programmable delay block (PDB) • 16-bit resolution

• 3-bit prescaler

• Positive transition of trigger event signal initiates the counter

• Supports two triggered delay output signals, each with an independently-

controlled delay from the trigger event

• Outputs can be OR'd together to schedule two conversions from one input

trigger event and can schedule precise edge placement for a pulsed output.

This feature is used to generate the control signal for the CMP windowing

feature and output to a package pin if needed for applications, such as

critical conductive mode power factor correction.

• Continuous-pulse output or single-shot mode supported, each output is

independently enabled, with possible trigger events

• Supports bypass mode

• Supports DMA
