Digital Signal Controller
The MC56F825x/MC56F824x is a member of the 56800E
core-based family of digital signal controllers (DSCs). 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 a cost-effective solution. Because of its
low cost, configuration flexibility, and compact program
code, it is well-suited for many applications. The
MC56F825x/MC56F824x includes many peripherals that are
especially useful for cost-sensitive applications, including:
• Industrial control
• Home appliances
• Smart sensors
• Fire and security systems
• Solar inverters
• Battery chargers and management
• Switched-mode power supplies and power management
• Power metering
• Motor control (ACIM, BLDC, PMSM, SR, and stepper)
• Handheld power tools
• Arc detection
• Medical devices/equipment
• Instrumentation
• Lighting ballast
The 56800E core is based on a modified 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 compilers to enable rapid development
of optimized control applications.
The MC56F825x/MC56F824x supports program execution
from internal memories. Two data operands per instruction
cycle can be accessed from the on-chip data RAM. A full set
of programmable peripherals supports various applications.
Each peripheral can be independently shut down to save
power. Any pin, except Power pins and the Reset pin, can also
be configured as General Purpose Input/Outputs (GPIOs).
