3.1 56F8300 Series Core Features
The 56F8300 Series of devices is the latest set of components using the highly successful 56800/E
hybrid 16-bit MCU/DSP core. The 56F8300 Series utilizes the enhanced 56800 core, 56800E, that has
a number of improvements over the 56800 and blurs the line between 16-bit and 32-bit architectures.
Figure 1-5 shows the 56800E core architecture.
Figure 1-5. 56800E Core Architecture
Key features of the 56800E core include:
• Fully source code-compatible with the 56800 core
• Efficient 16-bit engine with dual Harvard architecture
• Up to 200 Million Instructions Per Second (MIPS) at 200MHz core frequency
• Single-cycle 16
× 16-bit parallel Multiplier-Accumulator (MAC)
• Four (4) 36-bit accumulators, including extension bits
• Flexible bit manipulation unit with 16- & 32-bit bidirectional shifter
• Parallel instruction set with unique addressing modes
• Hardware DO and REP loops (zero overhead)
• Three (3) internal address buses and one (1) external address bus
• Four (4) internal data buses and one (1) external data bus
• Internal 32-bit data buses
