1.5.
The C8051F000 MCU family has an on-board Programmable Counter/Timer Array (PCA) in addition to the four
16-bit general-purpose counter/timers. The PCA consists of a dedicated 16-bit counter/timer timebase with 5
programmable capture/compare modules. The timebase gets its clock from one of four sources: the system clock
divided by 12, the system clock divided by 4, Timer 0 overflow, or an External Clock Input (ECI).
Each capture/compare module can be configured to operate in one of four modes: Edge-Triggered Capture,
Software Timer, High Speed Output, or Pulse Width Modulator. The PCA Capture/Compare Module I/O and
External Clock Input are routed to the MCU Port I/O via the Digital Crossbar.
1.6.
The C8051F000 MCU Family includes a Full-Duplex UART, SPI Bus, and I2C/SMBus. Each of the serial buses is
fully implemented in hardware and makes extensive use of the CIP-51’s interrupts, thus requiring very little
intervention by the CPU. The serial buses do not “share” resources such as timers, interrupts, or Port I/O, so any or
all of the serial buses may be used together.
