ANALOG DEVICES Estimating Power for ADSP-BF534/BF536/BF537 Blackfin Processors (Rev 2 05/2007) Manual

About this manual

This document outlines the methodology for estimating the total average power consumption of ADSP-BF534, ADSP-BF536, and ADSP-BF537 Blackfin embedded processors. The estimation is based on characterization data measured over power supply voltage (VDDINT), core frequency (CCLK), and junction temperature (TJ). It assists board designers in estimating their power budget for power supply design and thermal relief designs.

Frequently asked questions

What is the difference between high-performance and low-power Blackfin processors in this document?

The ADSP-BF536 is a low-power derivative of the ADSP-BF537, while BF537s can run at faster internal clock speeds.

How is total power consumption calculated for these processors?

The total power consumption is the sum of the power consumed by both power supply domains, VDDINT and VDDEXT.
