LPC55S6x
32-bit ARM Cortex-M33 microcontroller
• Fifteen command buffers allow independent options selection and channel sequence
scanning.
• Automatic compare for less-than, greater-than, within range, or out-of-range with
"store on true" and "repeat until true" options.
• Two independent result FIFOs each contains 16 entries. Each FIFO has configurable
watermark and overflow detection.
• Interrupt, DMA, or polled operation.
• Linearity and gain offset calibration logic.
7.29.2 Comparator
The analog comparator can compare voltage levels on external pins and internal voltages.
The comparator has five inputs multiplexed separately to its positive and negative inputs.
7.29.2.1 Features
• Selectable external inputs can be used as either the positive or negative input of the
comparator.
• Voltage ladder source selectable between the supply, multiplexing between internal
VBAT_PMU and ACMPVREF.
• 32-stage voltage ladder can be used as either the positive or negative input of the
comparator.
• Supports standard and low power modes
• Interrupt capability.
