This EE-Note discusses the methodology for estimating total average power consumption of ADSPBF561 Blackfin® embedded symmetric multiprocessors. Power estimates are based on characterization data measured over power supply voltage, core frequency (CCLK), and junction temperature (TJ). The intent of this document is to assist board designers in estimating their power budget for power supply design and thermal relief designs using Blackfin dual-core processors. These processors feature dynamic power management control, allowing the regulation of applied core voltage (VDDINT) from an external I/O source (VDDEXT). The ranges for these supplies differ depending on the part being used.
