DSP56301AG100

Digital Signal Processor Dsp Overview

The DSP56301AG100 is a 24-bit Digital Signal Processor from the DSP56300 core family, manufactured by NXP USA Inc. (formerly Freescale Semiconductor). It delivers 80 or 100 MIPS performance using an internal 80/100 MHz clock at a supply voltage of 3.0–3.6 V. The device features a fully pipelined 24x24-bit MAC with 56-bit accumulators and a barrel shifter. Internal memory includes up to 8 K x 24-bit 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 Procurement Notes

Verify the specific ordering suffix for package type (TQFP or MAP-BGA) and lead-free status against the official datasheet. Confirm that the AG100 designation corresponds to the 100 MHz speed grade. Ensure compatibility with the required 3.0–3.6 V supply domain and check for obsolete status as the product originates from legacy Freescale/NXP portfolios.

Digital Signal Processor Dsp Selection Notes

Select this component for general-purpose digital signal processing requiring high throughput in multimedia or telecommunications. The DSP56301 supports object code compatibility with the older DSP56000 core. Designers must account for multiple isolated power domains (VCCP, VCCQ, VCCA, etc.) and provide adequate decoupling. The choice between TQFP and MAP-BGA depends on pin count requirements and board space constraints.

Digital Signal Processor Dsp Part Context

The DSP56301 belongs to the DSP56300 core family, which also includes variants like the DSP56371 and DSP56374. These processors are designed for applications demanding significant computational horsepower in compact packages. The family utilizes programmable CMOS technology and offers low power dissipation through various standby modes.

Digital Signal Processor Dsp Replacement Considerations

The datasheet notes object code compatibility with the DSP56000 core. For higher performance imaging radar applications, NXP offers the S32R47 processor. However, direct pin-to-pin replacements within the same form factor are not explicitly listed in the provided documentation; migration typically requires architectural review.
