概述

Description

DSP56321VF275 is Freescale/NXP’s DSP56k family fixed‑point digital signal processor. It combines a 24-bit fixed‑point core with a Harvard architecture (separate program and data memory) and a fast MAC-based engine for real‑time DSP tasks.
Key features (typical):
- 24-bit fixed‑point math with MAC (multiply-accumulate) support
- DSP-oriented instructions and addressing: modulo/circular addressing, zero‑overhead loops, bit‑reversed addressing for FFT
- On‑chip RAM/ROM and flexible memory map
- Peripherals: serial interfaces (SCI/SPI), timers, PWM, I/O, and other DSP-friendly peripherals
- Packaging/variant indicated by VF275 suffix (package and temperature/variant spec)
Designed for automotive, motor control, audio, communications, and other real‑time DSP applications requiring deterministic processing and efficient DSP workflows. Development is via Freescale/NXP toolchains with C/C++ and DSP library support.

Features

DSP56321VF275 is a Freescale/NXP fixed-point DSP in the DSP56K family. Key features (concise):
- 32-bit fixed-point DSP core with Harvard architecture
- Dual 24×24-bit multiply-accumulate with a high-precision (40-bit) accumulator
- Pipelined core for high throughput
- Separate program and data memories (on-chip RAM; external memory interface)
- Rich serial/peripheral set: McBSP, SCI, SPI, I2C, timers, PWM, GPIO
- DMA controller and interrupt controller
- On-chip debugging support (JTAG/BDM)
- 275-pin VFQFP package (VF275)
Typical use: signal processing, telecom, audio, and motor-control applications requiring high MAC throughput in a large-pin package. For exact specs (clock speed, memory sizes, voltage, temp range), consult the official datasheet.

Package

It uses a plastic 208‑pin LQFP (Quad Flat Pack) package.
