Powered by GS/AI

The ADSP-2189MKST-300 is a high-performance digital signal processor optimized for various numeric processing applications. It features a 13.3 ns instruction cycle time and can achieve sustained performance of 75 MIPS, allowing for single-cycle instruction execution and context switching. The processor is built on a 3-bus architecture that supports dual operand fetches in every instruction cycle, enhancing computational efficiency. This DSP integrates 192K bytes of on-chip RAM, which includes 32K words of program memory and 48K words of data memory. It supports a range of multifunction instructions and includes independent computational units: an ALU, a multiplier/accumulator, and a barrel shifter. The device also features two independent data address generators and a powerful program sequencer that enables zero overhead looping and conditional instruction execution. The ADSP-2189MKST-300 supports flexible I/O operations with a 16-bit internal DMA port and an 8-bit DMA port for high-speed data transfers. It can interface with external memory and peripherals through a programmable memory strobe and supports multiple interrupt sources. The processor is packaged in a 100-lead LQFP and is suitable for applications requiring low power dissipation, making it ideal for battery-operated devices.
