The 56F8122, a member of the 56800E core-based family of Digital Signal Controllers, combines the processing power of a DSP and the functionality of a microcontoller. Inside a compact 48-pin LQFP, this device features 40 MIPS performance (at 40 MHz), along with 40 KB of on-chip Flash memory and a comprehensive set of peripherals.
56F8122 Features
- On-chip memory includes high-speed volatile and nonvolatile components:
- 32 KB of Program Flash
- 8 KB of Data RAM
- 8 KB of Boot Flash
- Up to 40 MIPS at 40 MHz execution frequency
- DSP and MCU functionality in a unified, C-efficient architecture
- JTAG/EOnCE for unobtrusive, real-time debugging
- Four 36-bit accumulators
- 16- and 32-bit bidirectional barrel shifter
- Parallel instruction set with unique addressing modes
- Hardware DO and REP loops available
- Three internal address buses
- Four internal data buses
- Architectural support for 8-, 16- and 32-bit single-cycle data fetches
- MCU-style software stack support
- Controller-style addressing modes and instructions
- Single-cycle 16 x 16-bit parallel multiplier-accumulator (MAC)
- Proven to deliver more control functionality with a smaller memory footprint than competing architectures
