1.2 56F807 Description
The 56F807 is a member of the 56800 core-based family of hybrid controllers. 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.
