Rochester Electronics Embedded - DSP (Digital Signal Processors) ADSP-2183KST-210

The ADSP-2183KST-210 is a digital signal processor optimized for high-speed numeric processing applications. It operates at a maximum frequency of 52 MHz with a 19 ns instruction cycle time, delivering a sustained performance of 52 MIPS. The processor features a 3-bus architecture that allows dual operand fetches in every instruction cycle, enabling efficient execution of single-cycle instructions and context switches. This DSP includes 80K bytes of on-chip RAM, configured as 16K words of program memory and 16K words of data memory, allowing for dual-purpose storage. It supports a comprehensive instruction set with extensions for bit manipulation and enhanced computational capabilities. The architecture includes independent computational units such as an ALU, a multiplier/accumulator, and a barrel shifter, along with two independent data address generators for efficient data handling. The ADSP-2183KST-210 provides extensive interfacing options, including a 16-bit internal DMA port for high-speed access to on-chip memory, a byte DMA port for external memory interfacing, and two double-buffered serial ports for synchronous communication. It also features a programmable timer, multiple external interrupts, and a power-down mode for low power dissipation, making it suitable for battery-operated devices. Available in a 128-lead LQFP package, the ADSP-2183KST-210 is compatible with the ADSP-2100 family, ensuring ease of integration into existing systems. This processor is ideal for applications requiring high-performance digital signal processing with flexible memory and interfacing capabilities.
