DSP56301PW100 概要
A 24-bit fixed-point DSP (Digital Signal Processor) is a specialized microprocessor whose datapath, registers, and ALUs are sized to 24 bits, giving roughly 144 dB of dynamic range at full precision - a sweet spot for audio codecs, speech codecs, and modem baseband processing. Within the broader hierarchy, fixed-point DSPs sit beside general-purpose microcontrollers as a class of programmable logic that excels at streaming arithmetic. The DSP56300 family delivers this precision via a Harvard architecture with separate X and Y data memories and a program memory, enabling single-cycle multiply-accumulate operations.
Key features include 100 MHz / 100 MMACS sustained throughput, separate X-data and Y-data RAM each organized as 24-bit words, a 24-bit program memory space, programmable wait states for external memory, a JTAG/OnCE debug port, and low-power stop and wait modes. The Host Interface supports direct connection to a microcontroller bus (e.g., Motorola/Freescale legacy hosts), easing system partitioning. The triple timer module provides three independent timers for scheduling, sampling, or event capture.
The DSP56300 architecture uses a three-bus Harvard design (program memory, X-data, Y-data) plus an on-chip enhanced filter coprocessor on certain family members, allowing the core to execute control code while filters run in parallel. The 24-bit datapath and dual-memory addressing support complex IIR/FIR filters, V.90 modems, MPEG audio decoding, and echo cancellation without intermediate precision loss.
Typical applications include audio processing (equalizers, effects, mixing), speech codecs for VoIP and telephony, video conferencing front-ends, cellular base station channel cards, modems (V.32bis/V.34/V.90), and industrial control loops requiring deterministic DSP performance. The part is also seen in legacy telecom infrastructure and pro-audio equipment.
Designers should note that the DSP56301PW100 is mature/last-time-buy silicon, so production designs should evaluate current alternatives - including the DSP56311 and DSP56321 families - while keeping the DSP56301PW100 footprint for long-lifecycle maintenance of installed bases. Plan firmware compatibility around the same instruction set and memory map.

主な用途
DSP56301PW100 の用途: 6 件s: Audio Processing and Effects, Speech Codecs and VoIP Front-End, Telephony and Modem Baseband, Video Conferencing Front-End, Cellular Base Station Channel Card, Industrial Control Loops.
Audio Processing and Effects
The DSP56301PW100's 24-bit datapath (about 144 dB dynamic range) and 100 MMACS throughput make it ideal for pro-audio effects units, mixers, and equalisers where high dynamic range and deterministic DSP performance are mandatory. In a typical topology the SSI port streams audio I/O to codecs such as the AK4528 or CS4272 while the core executes biquad cascades and FIR filters using the dual X/Y memories without precision loss. Compared with a 16-bit DSP, the 24-bit path avoids intermediate overflow in long FIRs and FFTs, simplifying algorithm design. Heatsinking is not required at audio clock rates, and the industrial temperature grade supports installation in live-sound consoles and broadcast gear.
おすすめ
Speech Codecs and VoIP Front-End
For speech codecs (G.729, G.723.1, MELP) and VoIP front-end processing, the DSP56301PW100 delivers enough MIPS to handle multiple channels at 8 kHz sample rate alongside echo cancellation. Its SCI enables connection to a host Ethernet controller for packet I/O, while the Host Interface allows shared-memory hand-off with a microcontroller running the IP stack. The 24-bit datapath preserves precision for adaptive filters in echo cancellers, where coefficient drift on a 16-bit path causes audible artefacts. Channel density of 4-8 simultaneous voice channels per device is realistic at 100 MMACS, suiting small PBX and IP-phone designs.
おすすめ
Telephony and Modem Baseband
Originally designed into V.32bis/V.34/V.90 modems, the DSP56301PW100 still fits modem and telephony baseband cards where its deterministic instruction timing and Host Interface simplify PC-card or set-top box integration. The triple timer generates precise DTE rates and frame clocks without software jitter, while the SSI ports to the analogue front-end. Designers porting legacy modem code will find the DSP56301 instruction set identical across the family, easing migration to the DSP56311 at 150 MHz. The part is widely seen in legacy telecom infrastructure for protocol stack maintenance.
おすすめ
Video Conferencing Front-End
Video conferencing terminals require echo cancellation, noise suppression, and audio compression - exactly the workload the DSP56301PW100 was designed for in the late 1990s NXP/Freescale reference designs. Typically paired with a host codec ASIC or DSP, it runs the audio path while the host handles H.26x video. The Host Interface supports DMA-style double-buffering for low-latency audio, and the industrial temperature grade allows operation in conference room equipment. With 100 MMACS available, designers can run G.168-compliant echo cancellers at 32-48 ms tail length comfortably.
おすすめ
Cellular Base Station Channel Card
Although superseded for greenfield 3G/4G designs, the DSP56301PW100 remains viable for maintenance and expansion of legacy GSM channel cards where timing determinism and DSP56300 codebases are already deployed. Its 100 MMACS of throughput channels 8-16 full-rate GSM traffic channels per device with voice-band processing, signalling demodulation, and channel equalisation. The Host Interface eases hand-off to a backplane controller, and the triple timer generates the TDMA frame clock. Designers of maintenance spares should verify NXP last-time-buy dates and stock at distributors before committing to extended support.
おすすめ
Industrial Control Loops
The deterministic timing and rich timer resources of the DSP56301PW100 make it a strong fit for industrial control loops running PID, state-space, or Kalman filters at fixed sample rates. Three independent timers let the DSP handle multiple control loops simultaneously - common in multi-axis motor control and process control - while the SSI ports to ADC and DAC peripherals. The industrial temperature grade suits factory-floor enclosures, and the JTAG/OnCE port simplifies in-circuit debug during commissioning. Real-time closed-loop periods under 10 microseconds are achievable thanks to single-cycle MAC operation.

設計ノート
Estimated: the DSP56301PW100 requires separate core (VDD) and I/O (VDDIO=3.3V) supplies; place 0.1uF ceramic decoupling capacitors within 5mm of each VDD/VDDIO pin pair, plus a bulk 10-47uF tantalum or polymer capacitor on each rail. The 208-LQFP has approximately 25 VDD pins and 35 GND pins distributed around the perimeter - tie ALL of them to their respective planes with at least 0.5mm-wide traces or vias directly to internal power/ground planes. Power sequencing: bring up the I/O supply before the core supply, or use a supply supervisor to avoid latch-up during hot-plug events.
The 208-LQFP package at 28x28 mm has a 0.5 mm lead pitch. Use 4-layer PCB with continuous ground and power planes beneath the device for low-impedance return paths and SSI/SCI signal integrity. Route the 24-bit external data bus D[23:0] and address bus A[23:0] with matched length matching within approximately 10 mm to preserve bus timing at 100 MHz. Place SSI, SCI, JTAG, and Host Interface signals on inner layers adjacent to the device to avoid stubs. Include a 4-layer impedance-controlled stack-up for reliable 100 MHz operation - estimated: microstrip impedance of 50 ohms requires approximately 0.20 mm trace width on 0.20 mm prepreg over a solid ground plane (verify with your stack-up manufacturer).
The DSP56301PW100 has separate X-data and Y-data memory buses - leaving the Y memory under-utilised wastes up to half the available memory bandwidth. A frequent issue is incorrect JTAG connection: TCK, TMS, TDI, TDO, and TRST must each be tied through a 10-100k pull-up to VDDIO if unused, otherwise the device may enter unknown states on reset. The PLL filter capacitor on PCAP must be a low-leakage NP0/C0G part - using X7R or Y5V will cause PLL jitter and increased cycle-to-cycle timing variation. Always assert RESET for at least 100 ms after both supplies are stable to guarantee proper initialisation.
Estimated: at 100 MHz in a 208-LQFP package, the DSP56301PW100 dissipates approximately 0.5-1.0W depending on peripheral activity. Use the package theta_JA figure of approximately 25-30 C/W (with adequate copper planes and airflow) to estimate junction temperature. Derate by at least 50% for industrial temperature grade designs to ensure margin at the upper end (-40C to +85C). Add thermal vias under the exposed pad area (and within the ground/power plane grid) to spread heat into inner planes. For sealed enclosures, verify worst-case temperature rise with a thermocouple on the package top during characterisation.
コンプライアンス情報
RoHS, REACH, lead-free and conflict-mineral status for the DSP56301PW100 were not present in the verified distributor listings. The Vyrian listing identifies the package as LFQFP with gull-wing terminals, suggesting a fine-pitch QFP construction, but does not state a material finish. Confirm RoHS compliance and the lead-free (Pb-free) finish with NXP's product change notification or a current manufacturer material declaration before placing orders for RoHS-required designs. AEC-Q100 does not apply: this is a digital signal processor for industrial/commercial DSP, not an automotive-qualified part. The part is listed as obsolete by Octopart but remains stocked at multiple distributors as of October 2026.
