C8051F350/1/2/3
1.6.
C8051F350/1/2/3 devices include a software-configurable voltage comparator with an input multiplexer.
The Comparator offers programmable response time and hysteresis and two outputs that are optionally
available at the Port pins: a synchronous “latched” output (CP0), or an asynchronous “raw” output (CP0A).
Comparator interrupts may be generated on rising, falling, or both edges. When in IDLE mode, these inter-
rupts may be used as a “wake-up” source for the processor. Comparator0 may also be configured as a
reset source. A block diagram of the Comparator is shown in Figure 1.9.
1.7.
The C8051F350/1/2/3 Family includes an SMBus/I2C interface, a full-duplex UART with enhanced baud
rate configuration, and an Enhanced SPI interface. Each of the serial buses is fully implemented in hard-
ware and makes extensive use of the CIP-51's interrupts, thus requiring very little CPU intervention.
