DSP56301VF80B1

Digital Signal Processor Dsp Overview

The DSP56301VF80B1 is a 24-bit Digital Signal Processor from the DSP56300 core family, manufactured by NXP USA Inc. It delivers processing performance of 80 or 100 MIPS using an internal 80 MHz or 100 MHz clock at supply voltages between 3.0 V and 3.6 V. The device features a fully pipelined architecture with a 24x24-bit MAC, two 56-bit accumulators, and a 56-bit barrel shifter. Internal memory includes up to 8 K x 24 bits of RAM and a 3 K x 24-bit bootstrap ROM. Key peripherals include a PCI-compliant Host Interface (HI32), two Enhanced Synchronous Serial Interfaces (ESSI), a Serial Communication Interface (SCI), and a Triple Timer module.

Digital Signal Processor Dsp Feature Summary

• DSP56300 Core: 80/100 MIPS performance at 80/100 MHz with 3.0–3.6 V operation.
• Memory Architecture: Configurable internal RAM (Program, X Data, Y Data) totaling 8 K x 24 bits and 3 K x 24-bit Bootstrap ROM.
• Peripherals: Includes HI32 (PCI Rev. 2.1 compliant), dual ESSI (six-channel audio support), SCI, and Triple Timer.
• Power Management: Fully static design operating down to 0 Hz, featuring Wait and Stop low-power modes.

Digital Signal Processor Dsp Applications

• Wireless and wireline infrastructure systems
• Multi-channel wireless local loop applications
• High-speed modem banks and packet telephony
• Video conferencing and cellular telephony

Digital Signal Processor Dsp Procurement Notes

Verify package type availability, as the DSP56301 is offered in 208-pin TQFP and 252-pin MAP-BGA configurations. Confirm lead-free status if required, as both packages are available in lead-bearing and lead-free versions. Ensure power supply decoupling meets the specific requirements for isolated VCC domains (VCCP, VCCQ, VCCA, etc.) described in the technical data.

Digital Signal Processor Dsp Selection Notes

Select based on required clock speed (80 MHz vs. 100 MHz) and package constraints (TQFP vs. BGA). Consider memory configuration needs, as Program RAM, Instruction Cache, and Data RAM sizes are programmable via hardware switches. Verify peripheral usage to ensure GPIO pin multiplexing does not conflict with required functions like ESSI or HI32.

Digital Signal Processor Dsp Part Context

The DSP56301 belongs to the DSP56300 core family, which maintains object code compatibility with the older DSP56000 core. This lineage ensures software portability while offering enhanced performance through a single-clock-cycle-per-instruction engine and integrated instruction cache. The device represents a high-performance CMOS solution for general-purpose digital signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should evaluate other members of the DSP56300 family or newer NXP DSP architectures for functional equivalence, ensuring instruction set compatibility and peripheral mapping alignment.
