3.4.3 CMPSS Module Variants

F280013x and F280015x devices contain two different variants of the CMPSS module: CMPSS (full module) and the CMPSS_LITE (reduced functionality and performance). The differences in features between the two variants are summarized in Table 3-6. CMPSS_LITE is the only comparator module available in F28E12x devices.
Table 3-6 CMPSS and CMPSS_LITE Feature Comparison
Feature CMPSS CMPSS_LITE
High and low comparators Yes Yes
Dual 12-bit reference DACs Yes Yes
DAC ramp generation Yes No
Low DAC output on external pin Yes (Some instances) No
Digital filters Yes Yes
Performance Full Performance (See CMPSS electrical characteristics in data manual) Some Reduced Performance (See CMPSS electrical characteristics in data manual)
