1.2 56F807 Description
The 56F807 is a member of the 56800 core-based family of processors. It combines, on a single chip, the
processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to
create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact
program code, the 56F807 is well-suited for many applications. The 56F807 includes many peripherals
that are especially useful for applications such as motion control, smart appliances, steppers, encoders,
tachometers, limit switches, power supply and control, automotive control, engine management, noise
suppression, remote utility metering, industrial control for power, lighting, and automation.
The 56800 core is based on a Harvard-style architecture consisting of three execution units operating in
parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and
optimized instruction set allow straightforward generation of efficient, compact DSP and control code.
The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized
control applications.
The 56F807 supports program execution from either internal or external memories. Two data operands can
be accessed from the on-chip Data RAM per instruction cycle. The 56F807 also provides two external
dedicated interrupt lines and up to 32 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
The 56F807 controller includes 60K, 16-bit words of Program Flash and 8K words of Data Flash (each
programmable through the JTAG port) with 2K words of Program RAM and 4K words of Data RAM. It
also supports program execution from external memory.

External Crystal Oscillator Input—This input should be connected to
an 8MHz external crystal or ceramic resonator. For more information,
please refer to Section 3.4.

This pin can also be connected to an external clock source. For more
information, please refer to Section 3.4.2.
Clock Output—This pin outputs a buffered clock signal. By programming
the CLKOSEL[4:0] bits in the CLKO Select Register (CLKOSR), the user
can select between outputting a version of the signal applied to XTAL and
a version of the device’s master clock at the output of the PLL. The clock
frequency on this pin can also be disabled by programming the
CLKOSEL[4:0] bits in CLKOSR.
