Analog Devices Inc. ADSP-2181 Digital Signal Processor, part number ADSP-2181BST-133, is a 16-bit fixed-point DSP featuring 8192 words of on-chip data RAM and 24-bit external data bus width. Operating at a maximum clock frequency of 16.67 MHz, this CMOS device delivers sustained 33 MIPS performance with single-cycle instruction execution. The architecture supports multiple internal buses, a barrel shifter, and two DMA channels. It includes two serial I/O ports and four external interrupts, along with one timer. Designed for surface mounting, the ADSP-2181BST-133 is housed in a 128-terminal, rectangular, low-profile fine-pitch quad flat package (LFQFP). Operating within a temperature range of -40°C to 85°C, it requires a supply voltage of 4.5V to 5.5V. Applications include telecommunications, industrial control, and audio processing.
