DSP56301PW80

Digital Signal Processor Dsp Overview

The DSP56301PW80 is a 24-bit fixed-point digital signal processor from the DSP56300 core family, manufactured by NXP USA Inc. It operates at clock rates of 66 MHz, 80 MHz, or 100 MHz, delivering corresponding performance of 66, 80, or 100 MIPS at a supply voltage of 3.0V to 3.6V. The device integrates an internal PLL, instruction cache, and six-channel DMA controller within a 208-LQFP surface-mount package. It supports object code compatibility with the legacy DSP56000 core.

Digital Signal Processor Dsp Feature Summary

• DSP56300 Core: Features a fully pipelined 24x24-bit parallel multiplier-accumulator, 56-bit barrel shifter, and nested hardware DO loops.
• Memory Architecture: Includes programmable on-chip Program RAM (up to 4096 x 24 bits), Instruction Cache (up to 1024 x 24 bits), and X/Y Data RAM (up to 3072 x 24 bits each).
• Peripheral Interfaces: Equipped with a 32-bit PCI/Universal Host Interface (HI32), two Enhanced Synchronous Serial Interfaces (ESSI), SCI, Triple Timer, and up to 42 GPIO pins.
• Power Management: Supports Wait and Stop low-power standby modes with fully-static logic allowing operation down to 0 Hz (DC).

Digital Signal Processor Dsp Applications

• Videoconferencing systems
• Cellular telephony baseband processing
• General-purpose multimedia applications

Digital Signal Processor Dsp Procurement Notes

Verify component status as the DSP56301PW80 is listed as Obsolete in distributor databases. Confirm RoHS compliance status, as specific listings indicate non-compliance for this part number. Ensure availability of the required datasheets (DSP56301 Technical Data) for design implementation.

Digital Signal Processor Dsp Selection Notes

Select the DSP56301PW80 when existing designs require migration from the DSP56000 core while maintaining object code compatibility. Choose the 80 MHz variant if the system requires 80 MIPS throughput. Verify that the host interface requirements align with the available HI32, ESSI, or SCI peripherals.

Digital Signal Processor Dsp Part Context

This component belongs to the DSP563xx series, specifically utilizing the DSP56300 architecture. It serves as a successor to the DSP56000 family, offering increased speed and integrated peripherals such as the OnCE emulation module and JTAG test access port.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacement with other DSP56300 family members is not supported due to pin function reorganization. Consider the DSP56303 for hardware migration projects requiring PBGA packaging and enhanced DMA capabilities.
