1.2 Device Description
The 56F8365 and 56F8165 are members of the 56800E core-based family of controllers. Each combines,
on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a
microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because
of their low cost, configuration flexibility, and compact program code, the 56F8365 and 56F8165 are
well-suited for many applications. The devices include many peripherals that are especially useful for
motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and
control, automotive control (56F8365 only), 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 56F8365 and 56F8165 support program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. These devices also provide two external
dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
1.2.1
The 56F8365 controller includes 512KB of Program Flash and 32KB of Data Flash (each programmable
through the JTAG port) with 4KB of Program RAM and 32KB of Data RAM. A total of 32KB of Boot
Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used
