Freescale Semiconductor Tower System Kit TWR-56F8400 TWR-56F8400-KIT TWR-56F8400-KIT Guia De Informação

The 56F844x/5x/7x is the initial family of 32-bit 56800EX
core–based Digital Signal Controllers (DSCs). Each device in
the family combines, on a single chip, the processing power of
a 32-bit DSP and the functionality of a microcontroller with a
flexible set of peripherals. Due to its cost-effectiveness,
configuration flexibility, and compact program code, the
56F844x/5x/7x is well-suited for many consumer and
industrial applications.

The 56800EX core is based on a dual 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. Additionally, memory
resource protection (MRP) is provided to protect supervisor
programs and resources from user programs.

The 56F844x/5x/7x supports up to 100 MHz program
execution from both internal flash memory and RAM. Both
on-chip flash memory and RAM can also be mapped into both
program and data memory spaces. Two data operands can be
accessed from the on-chip data RAM per instruction cycle.
