ADSP-2115BS-66

Digital Signal Processor Dsp Overview

The ADSP-2115BS-66 is a 16-bit fixed-point DSP microprocessor from the Analog Devices ADSP-2100 family. It features an enhanced Harvard architecture with three independent buses for simultaneous instruction fetch and dual data operand access. The device integrates 1K words of program RAM and 512 words of data RAM, along with two synchronous serial ports (SPORTs) and a programmable interval timer. Operating at a maximum clock frequency of 25 MHz with a 40 ns instruction cycle time, it delivers 25 MIPS performance. Key architectural components include an ALU, multiplier/accumulator, shifter, and two data address generators supporting modulo and bit-reverse addressing.

Digital Signal Processor Dsp Feature Summary

• Enhanced Harvard Architecture: Three-bus system allowing single-cycle execution of instructions, data moves, and computations.
• Integrated Memory: On-chip 1K word Program RAM and 512 word Data RAM.
• High Performance: 25 MIPS throughput at 25 MHz clock speed (40 ns instruction cycle).
• Serial Communication: Dual double-buffered Serial Ports (SPORT0 and SPORT1) with hardware companding support.

Digital Signal Processor Dsp Applications

• Digital signal processing applications requiring high-speed numeric computation.
• Systems utilizing automatic booting from byte-wide external memory such as EPROM.
• Audio or telecommunications interfaces leveraging SPORT multichannel capabilities.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as this part may be discontinued. Ensure proper handling for moisture sensitivity if applicable. Validate package type against design requirements before procurement.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-2115BS-66 for applications needing 16-bit fixed-point processing with on-chip memory constraints. Compare against ADSP-2101 for similar features or ADSP-2111 if a host interface port is required. Consider the BS-66 suffix for specific speed grade and temperature range verification against the datasheet specifications.

Digital Signal Processor Dsp Part Context

This processor belongs to the ADSP-2100 Family, which shares a common core architecture. Variants like the ADSP-2101 and ADSP-2103 differ primarily in voltage and memory size. The ADSP-2115 specifically offers 1K program RAM and 512 data RAM, distinguishing it from the ADSP-2111 which includes a Host Interface Port instead of additional standard peripherals.
