MC56F81xxx | Entry-level Digital Signal Controllers

Overview

The MC56F81xxx family is NXP’s new entry-level Digital Signal Controllers (DSC) product. This high efficiency family is based on the high performance 56800EX DSP core, with frequency up to 100MHz. This family extends the DSC products’ cost performance to the best, it’s NXP’s first DSC product to integrate a Digital Signature Algorithm Security Subsystem (DSASS) and high-speed low-power operational amplifier. Comparing with the MC56F82xxx family, the MC56F81xxx family extends the memory to 128KB Flash, 20KB RAM and 64KB boot ROM. In addition, MC56F81xxx family has lots of feature enhancements to the MC56F82xxx family include enhanced DMA function (eDMA), configurable logic Event Generator (EVTG), dual 1.6MSps 12-bit ADC and full PMBus support. The MC56F81xxx family offers extremely cost-effective solution for power conversion and motor control applications.

To develop any part of 56F81xxx series with Config Tool, please use the MC56F81xxx template. These template projects are extracted from related SDK packages and contain all the necessary drivers. Config tool provides GUI interface to easily configure pins, clock, peripherals and middleware such as FreeMASTER. Follow below steps to start the development:
1. Download and unzip the package
2. Import the project with desired part number to CodeWarrior workspace. Suggest copying the project into workspace during the importing by checking “Copy projects into workspace” checkbox in “Import Projects” dialogue
3. Go to the imported project folder and open the mex file with Config tool to start the development
