Analog Devices Inc. ADSP-2181BS-115 is a 16-bit fixed-point Digital Signal Processor from the ADSP2181 series. This CMOS device operates at a maximum clock frequency of 14.4 MHz, delivering 33 MIPS sustained performance with single-cycle instruction execution. It features a 14-bit address bus and a 24-bit extended data bus, complemented by multiple internal bus architectures. On-chip resources include 8192 RAM words for data, a barrel shifter, and 2 DMA channels. The processor supports 4 external interrupts and 2 serial I/O ports, along with one timer. Packaged in a 128-terminal PQFP (JESD-30 Code S-PQFP-G128) with a 0.80mm terminal pitch, it operates within a supply voltage range of 4.5V to 5.5V and an industrial temperature range of -40°C to 85°C. This component finds application in telecommunications, audio processing, and industrial control systems.
