1.2 56F8345 Description
The 56F8345 is a member of the 56800E 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 56F8345 is well-suited for many
applications. The 56F8345 includes many peripherals that are especially useful for 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 applications.
The 56800E 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 56F8345 supports program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. The 56F8345 also provides two
external dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines,
depending on peripheral configuration.
The 56F8345 hybrid controller includes 128KB of Program Flash and 8KB of Data Flash (each
programmable through the JTAG port) with 4KB of Program RAM and 8KB of Data RAM.
A total of 8KB of Boot Flash is incorporated for easy customer-inclusion of field-programmable
