Overview
The ADSP-2186MBSTZ-266, produced by Analog Devices Inc., is a high-performance digital signal processor (DSP) optimized for digital signal processing and other high-speed numeric processing applications. This single-chip microcomputer integrates the ADSP-2100 family base architecture, which includes three computational units, data address generators, and a program sequencer. It also features two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, and extensive interrupt capabilities. The processor is designed to meet the low power needs of battery-operated portable equipment with its power-down circuitry and low CMOS standby power dissipation.
