The ADSP-2185NKSTZ-320 is a high-performance 16-bit fixed-point digital signal processor from the ADSP-218xN series by Analog Devices. It delivers 80 MIPS sustained performance with a 12.5 ns instruction cycle time at 1.8V core voltage. The device features a 3-bus architecture enabling dual operand fetches per cycle, single-cycle instruction execution, and single-cycle context switch.
Key integrated features include 80 kB of on-chip RAM configurable as program and data memory, an external memory interface supporting up to 4 Mbyte, and a 16-bit internal DMA port for high-speed memory access. The processor includes independent ALU, multiplier/accumulator, and barrel shifter computational units, along with two data address generators and a programmable sequencer with zero-overhead looping.
The ADSP-2185NKSTZ-320 operates from 1.8V, 2.5V, or 3.3V supplies with all inputs tolerant to 3.6V. It is housed in a 100-lead LQFP package (14x14 mm) and supports surface mount assembly. The device includes a host interface, two serial ports, six external interrupts, 13 programmable I/O lines, and an internal 16-bit interval timer.
The ADSP-2185NKSTZ-320 operates at a clock rate of 80 MHz.
