C8051F91x-C8051F90x
1.6.
C8051F91x-C8051F90x devices include an on-chip programmable current reference (source or sink) with
two output current settings: low power mode and high current mode. The maximum current output in low
power mode is 63 µA (1 µA steps) and the maximum current output in high current mode is 504 µA (8 µA
steps).
1.7.
C8051F91x-C8051F90x devices include two on-chip programmable voltage comparators: Comparator 0
(CPT0) which is shown in Figure 1.9; Comparator 1 (CPT1) which is shown in Figure 1.10. The two
comparators operate identically but may differ in their ability to be used as reset or wake-up sources. See
Section “18. Reset Sources” on page 171 and the Section “14. Power Management” on page 143 for
details on reset sources and low power mode wake-up sources, respectively.
The Comparator offers programmable response time and hysteresis, an analog input multiplexer, and two
outputs that are optionally available at the Port pins: a synchronous “latched” output (CP0, CP1), or an
asynchronous “raw” output (CP0A, CP1A). The asynchronous CP0A signal is available even when the
system clock is not active. This allows the Comparator to operate and generate an output when the device
is in some low power modes.
The comparator inputs may be connected to Port I/O pins or to other internal signals. Port pins may also be
used to directly sense capacitive touch switches. See Application Note AN338 for details on Capacitive
Touch Switch sensing.
