DSP56303AG100R2 Présentation

The NXP DSP56303AG100R2 is a 24-bit fixed-point digital signal processor (DSP) from the DSP56300 family, clocked at 100 MHz and housed in a 144-pin LQFP (20x20 mm) package. It delivers up to 100 MIPS of processing throughput, integrating 24 KB of on-chip data RAM, 576 bytes of bootstrap ROM, and a triple-timer module for system event scheduling. The device targets cost-sensitive, high-performance signal-processing applications where deterministic real-time response and low power dissipation are required.

A digital signal processor (DSP) is a specialized microprocessor architecture optimized for the rapid arithmetic operations required by digital filters, codecs, modems, and audio/speech algorithms. Unlike general-purpose CPUs, DSPs feature single-cycle multipliers, dedicated accumulators, and Harvard-style memory architectures that allow simultaneous program and data fetches. The DSP56300 family specifically introduced an object-oriented programming model and aggressive clocking (up to 150 MHz in later siblings) to enable a new generation of wireless, telecommunications, and multimedia products.

Key features of the DSP56303AG100R2 include the 100 MHz core clock, on-chip Host Interface (HI08), two Enhanced Synchronous Serial Interfaces (ESSI), a Serial Communications Interface (SCI), and a 24-bit data path with hardware DO/LOOP hardware accelerators. The 1.8 V core / 3.3 V I/O split-rail design reduces power dissipation while maintaining compatibility with 3.3 V external logic, and the wide operating temperature range supports industrial-grade deployments.

Architecturally, the DSP56303 implements a 24-bit data ALU with a 56-bit accumulator, supporting fractional two's-complement arithmetic natively. The integrated Memory Expansion Area allows external program and data memory to be mapped linearly, simplifying glue-logic design. The peripheral set (ESSI/SCI/HI08/Timer) is accessed through a unified interrupt controller that supports prioritized, vectored interrupts, minimizing ISR latency for real-time control loops.

Typical applications include multi-line voice/data/fax processing, video conferencing endpoints, professional audio processing, general-purpose digital control systems, and embedded modems. The 100 MHz speed grade is well suited to voice-band codecs and basic speech recognition tasks, while remaining within the thermal envelope of a fan-less enclosure.

When designing with this device, allocate PCB real estate for the external memory bus; even with 24 KB on-chip RAM, many telecom workloads require an external SRAM or SDRAM. Decoupling must follow the datasheet recommendations (typically 0.1 µF + bulk per rail) and JTAG boundary-scan access should be brought out for production test.

Applications typiques

DSP56303AG100R2 convient pour 6 applications: Multi-Line Voice/Data/Fax Processing, Video Conferencing Endpoint, Professional Audio Processing, Industrial Digital Control Systems, Embedded Modem and Wireline Transceiver, General-Purpose Embedded DSP Platform.

🌐

Multi-Line Voice/Data/Fax Processing

The DSP56303AG100R2's 100 MIPS budget, 24-bit ALU and dual ESSI ports make it a strong fit for multi-line voice/fax platforms. Each DSP56303 instance can comfortably run 2-4 channels of G.711/G.729 codec, echo cancellation, and DTMF detection concurrently within thermal envelope. The HI08 host port glues cleanly into an external host CPU or MPC860-style communications processor, allowing shared memory-based signaling. Compared with a generic MCU, the hardware DO/LOOP and bit-field instructions accelerate inner DSP loops by 5-10x, reducing BOM cost by eliminating external accelerators.

🎥

Video Conferencing Endpoint

For H.320/H.323 video conferencing endpoints, the DSP56303AG100R2 handles audio pre-processing (AGC, noise reduction, acoustic echo cancellation) plus multiplexing of voice and data channels. Its 100 MHz speed grade processes stereo 16 kHz audio at full algorithmic headroom, while the dual ESSI ports accept frame-aligned audio from a companion video codec ASIC. The 1.8 V core / 3.3 V I/O split-rail design simplifies integration with 3.3 V video peripherals, and the 24 KB on-chip RAM holds per-channel buffers without external SRAM.

🎧

Professional Audio Processing

Studio audio gear, multi-effects processors and digital mixers benefit from the DSP56303AG100R2's deterministic 100 MIPS throughput and 24-bit data path. Each instance runs parametric EQ, dynamics, and reverb algorithms for 4-8 audio channels at 48 kHz with headroom to spare. The 56-bit accumulator eliminates intermediate-word-growth concerns common in IIR filter cascades, while the 24-bit I/O preserves dynamic range beyond 16-bit CD quality. The SCI port connects to front-panel control MCUs for preset recall, simplifying external DSP chains.

🏭

Industrial Digital Control Systems

In servo drives, motor controllers and power-converter feedback loops, the DSP56303AG100R2's deterministic single-cycle multiply-accumulate and triple-timer module deliver real-time control bandwidth. The 100 MIPS budget supports field-oriented control (FOC) for 1-2 PMSM axes at 20 kHz PWM rates with current-loop closures under 5 µs. The HI08 host port accepts commands from an industrial MCU, and the ESSI ports interface to digital Hall/encoder sensors without external glue. The wide operating temperature supports factory-floor deployment.

📡

Embedded Modem and Wireline Transceiver

The DSP56303AG100R2 implements V.90/V.92 soft-modem, ADSL front-end, and proprietary wireline codecs using its 100 MIPS and 24-bit signal integrity. The dual ESSI ports accept 16-bit sigma-delta ADC streams directly, while the SCI port manages handshake with the host CPU. The 24 KB on-chip RAM holds symbol tables and convolution buffers, eliminating the need for external SRAM in many designs. The 1.8 V core voltage keeps total power dissipation under 0.5 W typical, suitable for compact CPE enclosures.

🔧

General-Purpose Embedded DSP Platform

For custom signal-processing, instrumentation, and educational designs, the DSP56303AG100R2 offers a stable 100 MIPS platform with mature GNU and Tasking toolchains. The HI08 host port plus dual ESSI/SCI gives flexible host/sensor connectivity, and the JTAG port simplifies in-circuit debug. The 24 KB on-chip RAM suits prototype filter designs, and the external memory expansion bus accommodates cost-down to external SDRAM as designs scale. NXP's DSP56300 SDK provides reference filters, FFT kernels, and codec libraries to accelerate development.

According to the NXP DSP56303 datasheet, it integrates 24 KB of on-chip data RAM, 576 bytes of bootstrap ROM, two ESSI ports, one SCI, an HI08 host interface, and a triple-timer module. It is supplied in a 144-pin LQFP package (20x20 mm).
What is the difference between DSP56303AG100 and DSP56303AG100R2?
Both share the same DSP56303 silicon (100 MHz, 24 KB RAM, 144-LQFP). The DSP56303AG100 ships in Tray packaging while the DSP56303AG100R2 ships on Tape & Reel (the 'R2' suffix indicates the reel-pack ordering code per NXP's packaging convention). Functionally and electrically the two are identical; the difference is purely in delivery format for high-volume SMT lines.
Where can I buy DSP56303AG100R2?
The DSP56303AG100R2 is currently stocked at NXP authorized distributors including DigiKey (DigiKey part 1619430) and Mouser, with a typical lead time of immediate to several weeks. Pricing as of 2026-10-14 ranges from approximately $32.92 at qty-1 down to about $16.40 at qty-1000, based on DigiKey listing snapshots. For industrial volumes, requesting a direct quote from NXP is recommended given the part's NRD lifecycle status.
What is the price of DSP56303AG100R2?
As of 2026-10-14, the unit price at qty 1 is about $32.92, dropping to roughly $19.95 at qty 500 and approximately $16.40 at qty 1000 per DigiKey listings. LCSC shows a lower price of about $1.00 for fully licensed NXP stock, but buyers should verify authenticity and date code before sourcing from non-franchised distributors.
Is DSP56303AG100R2 still in production?
The DSP56303AG100R2 is marked NRD (Not Recommended for New Designs) by NXP. Existing inventory is still available through distributors, but NXP is steering new designs toward the DSP56321 or newer StarCore-based successors. For long-life-cycle programs, request the latest NXP product longevity statement before committing the design.
What is a drop-in replacement for DSP56303AG100R2?
A direct drop-in for the DSP56303AG100R2 is the DSP56303AG100 (Tray-pack variant of the same die) or the higher-speed DSP56303AG150 in the same 144-LQFP. None of these require PCB rework. For new designs, NXP's DSP56321AF150 in a similar BGA package offers substantially more performance but requires a footprint migration.
DSP56303AG100R2 vs DSPB56367AG150 - which is better?
The DSPB56367AG150 belongs to the DSPB56367 family with 150 MHz clock and additional peripheral integration, while the DSP56303AG100R2 is the original 100 MHz DSP56303 silicon. For a pure 100 MHz application the DSP56303AG100R2 is sufficient; for designs that need the extra throughput or peripherals the DSPB56367AG150 is the upgrade path, but it is NOT pin-to-pin compatible and requires a PCB redesign.
What is the best cross-brand equivalent for DSP56303AG100R2?
There is no true pin-compatible cross-brand equivalent for the DSP56303AG100R2, because the DSP56300 architecture, instruction set, and on-chip peripheral layout are NXP-proprietary. Texas Instruments' TMS320C55x and Analog Devices' SHARC families serve the same market segment but are not drop-in replacements - they require porting of all firmware and a new PCB layout. For a like-for-like migration, stay within the NXP DSP56300 family.
Where can I download the DSP56303AG100R2 datasheet PDF?
The official NXP datasheet for the DSP56303 family is available at https://www.nxp.com/docs/en/data-sheet/DSP56303.pdf, covering the DSP56303AG100 silicon revision in 108 pages of electrical, mechanical, and programming specifications. Octopart also mirrors the PDF at octopart.com/datasheet/nxp-semiconductors/DSP56303AG100R2 for convenience.
What is the pinout of the DSP56303AG100R2 in 144-LQFP?
The DSP56303AG100R2 uses the 144-LQFP pinout of the DSP56300 family, with dedicated pins for address bus (PAB), data buses (PDB0-23 / GDB0-23), control signals (BR, BG, BB, TA, TEA), the HI08 host port (H0-H7, HR/W, HEN, HREQ, HACK), two ESSI ports (SC0/SC1, SCK0/SCK1, SRD0/SRD1, STD0/STD1), the SCI port (SCLK, TXD, RXD), three timer outputs (TIO0-2), and the JTAG pins (TCK, TMS, TDI, TDO, TRST).
What are the key specifications of DSP56303AG100R2 that engineers should know?
The DSP56303AG100R2 combines 100 MHz core clock, 100 MIPS throughput, 24 KB on-chip data RAM, 576 B bootstrap ROM, 24-bit ALU with 56-bit accumulator, 1.8 V core / 3.3 V I/O supplies, and a 144-LQFP (20x20 mm) package. Its peripheral set (HI08 + 2x ESSI + SCI + Triple Timer) covers most voice/audio/control workloads without external glue logic. The DSP56300 instruction set supports hardware DO/LOOP and bit-field operations, accelerating inner loops common in codec and modem code.
Can DSP56303AG100R2 be used for audio processing?
Yes, the DSP56303AG100R2 is well suited to audio processing, including multi-line voice, conferencing codecs, and professional audio effects. Its 100 MIPS budget comfortably handles full-duplex G.711/G.729/A-law/μ-law codecs, basic echo cancellation, and parametric EQ. The two ESSI ports connect directly to common audio ADCs/DACs (e.g., Crystal CS43xx or TI TLV320 series) without external glue logic, simplifying the BOM.
Is DSP56303AG100R2 suitable for new industrial designs?
For new industrial designs the DSP56303AG100R2 is technically suitable but commercially risky due to its NRD lifecycle status. NXP continues to ship existing inventory, but allocation is limited and last-time-buy notices may arrive with short notice. For long-life programs, choose the active DSP56321 or consult NXP field application engineering for the recommended successor part number.
What is the lead time for DSP56303AG100R2?
Current distributor lead time for the DSP56303AG100R2 is approximately 2-4 weeks at major authorized distributors such as DigiKey and Mouser, based on snapshot data from 2026-10-14. LCSC and Heisener also list in-stock quantities (4,064 pieces on Heisener as of the snapshot date). Because the part is NRD, do not assume indefinite availability - confirm with the distributor's customer service team before placing a volume order.
DSP56303AG100 vs DSP56301AG80 - are they interchangeable?
The DSP56303AG100 (100 MHz) and DSP56301AG80 (80 MHz) belong to the same DSP56300 family but are NOT drop-in interchangeable. They share the 144-LQFP package and many peripheral features, but the DSP56301 lacks the third timer and has a smaller on-chip RAM configuration. For a simple swap, the DSP56303AG100 is the higher-performance superset, but always verify the specific peripheral map against your firmware's register assumptions.

Guide de sélection

Choose the DSP56303AG100R2 when you need a 100 MHz DSP56300-family processor in a 144-LQFP for voice/audio/control applications and you can accept its NRD lifecycle status. Choose the DSP56303AG100 (Tray variant) if you are hand-loading prototypes or low-volume production. Choose the DSP56301AG80 if your design only needs 80 MIPS and the reduced peripheral set, or if DSP56303 stock is constrained. Choose the DSPB56367AG150 if you need a 150 MHz speed grade within the same footprint for future-proofing. Avoid the DSP56303 family for brand-new industrial programs unless you have NXP longevity confirmation - newer NXP DSC and i.MX RT platforms are recommended for new designs.

Principaux différenciateurs

  • Industry-standard 100 MIPS DSP56300 family with mature Toolchain (vs DSP56301AG80)
  • Active 150 MHz upgrade path within the same footprint (vs DSPB56367AG150)
  • Split 1.8 V/3.3 V supply reduces power dissipation (vs TMS320C55x (TI))

Notes de conception

The DSP56303AG100R2 uses a split-rail supply: 1.8 V for internal core logic and 3.3 V for I/O pads. Both rails must be brought up simultaneously (or core first then I/O) per datasheet power-sequencing requirements. Estimated: at 100 MHz with all peripherals active, the core draws about 150-180 mA from the 1.8 V rail; I/O current depends on switching frequency. Place 0.1 µF ceramic decoupling within 5 mm of each VDD pin and a 10 µF bulk capacitor per supply rail.

Route the 24-bit program/data buses (PDB0-23, GDB0-23) with matched trace lengths (±1 cm) and 50 Ω characteristic impedance to avoid timing skew on the external memory bus. Keep address and data traces on inner layers with continuous ground reference planes. Place external SRAM/SDRAM within 5 cm of the DSP to minimize bus loading. The MODA/MODB/MODC/MODD bootstrap-mode pins require 10 kΩ pull-ups to VDD_IO for normal operation.

The 144-LQFP package has no exposed thermal pad, so dissipation is limited to about 1 W continuous without airflow. Estimated: at full 100 MIPS activity the junction temperature rise is roughly 25-30 °C above ambient on a standard 4-layer JEDEC PCB, which keeps the part within commercial-grade limits. For industrial-temperature deployments, derate clock speed or provide 100 LFM airflow.

ESSI/SCI lines are 3.3 V CMOS with relatively weak drive strength (4-8 mA typical). Series-terminate long traces (>5 cm) with 33 Ω resistors to dampen reflections. The JTAG chain (TCK/TDI/TMS/TRST) must be buffered for boards with multiple scan devices; ensure TRST has a 10 kΩ pull-up and a 1 nF cap to ground for clean reset on power-up.

Do not confuse the DSP56301 (which uses a 144-LQFP but lacks the third timer) with the DSP56303. Always check the silicon revision by reading the JTAG IDCODE register at reset. Also, the MODx bootstrap pins are sampled only at RESET de-assertion; pull-ups must be stable before RESET goes high. Finally, the HI08 host port requires the host CPU to drive HR/W and HEN during accesses - leaving these floating causes bus contention on the host interface.
