Rochester Electronics Embedded - DSP (Digital Signal Processors) ADSP-2183BST-160

The ADSP-2183BST-160 is a digital signal processor optimized for high-speed numeric processing applications. It operates at a maximum frequency of 40 MHz with a 19 ns instruction cycle time, achieving a sustained performance of 52 MIPS. The processor features a 3-bus architecture that allows dual operand fetches in every instruction cycle and supports single-cycle instruction execution and context switching. This DSP integrates 80K bytes of on-chip memory, including 16K words of program memory and 16K words of data memory, and is compatible with the ADSP-2100 family instruction set. It includes two independent data address generators, a powerful program sequencer for zero overhead looping, and multifunction instructions for enhanced processing capabilities. The ADSP-2183BST-160 supports various system interfaces, including a 16-bit internal DMA port for high-speed access to on-chip memory and an 8-bit DMA port for transparent program and data memory transfers. It also features two double-buffered serial ports for synchronous communication, programmable flag pins for flexible signaling, and extensive interrupt capabilities. This processor is available in a 128-lead LQFP package and is suitable for applications requiring efficient digital signal processing with low power dissipation, making it a viable option for engineers looking to implement DSP solutions in their projects.
