Product Overview
The DSP56303AG100 is a high‑performance 24‑bit fixed‑point DSP from NXP (Freescale) DSP56300 family. It runs up to 100 MHz / 100 MIPS, for audio, telecom and industrial signal processing. Harvard architecture with program/data RAM and boot ROM, packaged in 144‑LQFP(20mm×20mm). Note: This device is obsolete / NRND, no new production.
Core Advantages
High‑precision 24‑bit Processing Engine
24‑bit data path with 56‑bit accumulator, higher dynamic range than 16‑bit fixed‑point DSP.
100 MIPS High‑throughput Performance
100 MHz core clock, single‑cycle MAC for intensive signal‑computing tasks.
Complete Peripheral Set
HDI08 host port, dual ESSI, SCI, multi‑channel timer and OnCE on‑chip debug interface.
Low‑power Operation
Supports Wait / Stop power‑saving modes, independent core and I/O power domains.

Frequently Asked Questions
Q1: What is lifecycle status of DSP56303AG100?
A: Obsolete / NRND. Original manufacturer discontinued production, only surplus stock available, not recommended for new‑design projects.
Q2: What do suffix letters and numbers mean for DSP56303 series?
A:
- A = Industrial temperature grade
- G = Pb‑free package
- 100 / 80 = Maximum core frequency(MHz)
- Commercial‑grade version has narrower temperature range, cannot direct drop‑in without firmware verification.
Q3: What is maximum operating clock speed of DSP56303AG100?
A: Max core clock 100 MHz, provides 100 MIPS signal‑processing performance.
Q4: Are there pin‑to‑pin compatible replacement parts?
A: No true pin‑to‑pin drop‑in alternative. DSP56302 / DSP56301 in same family have smaller on‑chip memory, hardware & firmware modification required. For new design, choose modern ARM‑based DSP.
Q5: What is package dimension for DSP56303AG100?
A: 144‑LQFP, body size 20mm×20mm, pin pitch 0.5mm.
Q6: What is difference between ambient temperature and junction temperature?
A: Industrial ambient operating range: -40℃ ~ +85℃. +100℃ is absolute maximum junction temperature, not normal working ambient parameter.
Q7: How to get datasheet and quotation?
A: Submit quick‑inquiry form for original datasheet, pinout table, real‑time stock and volume price.
