With the CIP-51's maximum system clock at 25 MHz, it has a peak throughput of 25 MIPS. Figure 1.5
shows a comparison of peak throughputs of various 8-bit microcontroller cores with their maximum system
clocks.

1.1.3. Additional Features
The C8051F206, C8051F220/1/6 and C8051F230/1/6 have several key enhancements both inside and
outside the CIP-51 core to improve overall performance and ease of use in end applications.
The extended interrupt handler provides 22 interrupt sources into the CIP-51 (as opposed to 7 for the stan-
dard 8051), allowing the numerous analog and digital peripherals to interrupt the controller. (An interrupt
driven system requires less intervention by the MCU, giving it more effective throughput.) The extra inter-
rupt sources are very useful when building multi-tasking, real-time systems.
There are up to six reset sources for the MCU: an on-board
VDD monitor, a Watchdog Timer, a missing
clock detector, a voltage level detection from Comparator 0, a forced software reset, and an external reset
pin. The RST pin is bi-directional, accommodating an external reset, or allowing the internally generated
reset to be output on the RST pin. The on-board
VDD monitor is enabled by pulling the MONEN pin high
(digital 1). The user may disable each reset source except for the
VDD monitor and Reset Input Pin from
software. The watchdog timer may be permanently enabled in software after a power-on reset during
MCU initialization.
The MCU has an internal, stand-alone clock generator that is used by default as the system clock after
reset. If desired, the clock source may be switched "on the fly" to the external oscillator, which can use a
crystal, ceramic resonator, capacitor, RC, or external clock source to generate the system clock. This can
be extremely useful in low power applications, allowing the MCU to run from a slow (power saving) exter-
nal crystal source, while periodically switching to the fast (up to 16MHz) internal oscillator as needed.
