PRODUCTION DATA
This device features one enhanced comparator. The enhanced comparator is an analog voltage comparator with a built-in 6-bit DAC as an internal voltage reference. The integrated 6-bit DAC can be set to 64 steps for the comparator reference voltage. This module has 4-level programmable hysteresis and configurable power modes: high-power and low-power modes.
The eCOMP0 supports a propagation delay up to 1 µs in high-power mode. In low-power mode, eCOMP0 supports 3.2-µs delay with 1.5-µA leakage at room temperature, which can be an ideal wake-up source in LPM3 for a voltage monitor.
eCOMP0 contains a programmable 6-bit DAC that can use the internal shared reference (1.5 V, 2.0 V, or 2.5 V) for a high-precision comparison threshold. In addition to the internal shared reference, a low-power 1.2‑V reference is fixed at channel 2 of both the inverting and noninverting paths and allows the DAC to be turned off to reduce power consumption.
The eCOMP0 supports external inputs and internal inputs (see Table 9-21) and outputs (see Table 9-22)
